The nuances of particle solubility in a given solvent should ultimately be investigated by the experimenter during assay optimization and this guide is not a substitute for bench top evaluation.Adapted from: Brandrup, J., and When the value of increased up to ~0.4, the island-like PMMA features were finally connected to each other and formed larger domains (Figure 4(b)). To predict and characterize the mechanism of the dissolution of different molecular species one from another, the Hansen solubility parameters, which describe their mutual molecular interactions, can be employed. The presence of hydrogen bonding in the blends in the solid state has also been indicated by FTIR studies. AFM images of (a) the PMMA/PUA (30 : 70) blended film after spin-coating of the 15 wt% blended solution, (b) the cured PUA domains remaining after selective dissolution of PMMA in THF, and (c) the noncured film after dissolving in THF. Solubility exists on a spectrum. As illustrated in Figure 1, the cross-linked PUA domains remain even after dissolving the blended film in THF, whereas the PMMA domains are completely dissolved in THF. Averaged height differences between the cured PUA domains and the PMMA domains before the THF treatments were ~35 nm, ~72 nm, and ~157 nm for the 10 wt%, 15 wt%, and 20 wt% blended solutions, respectively (Figures 3(a)–3(c)). Phase separation and selective dissolution in the PMMA/PUA blend are schematically illustrated in Figure 1. Note that the substrate exposure induced from the selective dissolution without additional etching process can be applied to further applications, such as antireflection layers. In a simpler approach valid for slightly polar solvents, the capacity of a solvent to dissolve a polymer can be estimated by means of the Hildebrand solubility parameter (see regular solution theory in Section 6.3.3) defined as the square root of the cohesive energy: The densities of the polymer solutions in THF … @article{ee4718f3e9094d13a3e4b41dc08c1b6a.

Spin-coating is a simple method for fabricating thin polymer films, which facilitates precise and easy control of film thickness by rotational velocity and concentration of polymer solution [8, 9]. author = "M. Selvakumar and Bhat, {D. Krishna} and Renganathan, {N. G.}". Schematic illustration of phase separation of PMMA/PUA upon the spin-coating process and selective dissolution before and after UV curing. The phase separation of PMMA/PUA blend was well-driven via solvent evaporation during spin-coating. The effect of various solvents on the morphology of polymethyl methacrylate (PMMA) particles synthesized by spray drying is examined. Morphology of phase-separated structure, including domain size and height, could be controlled by varying total concentration of the blended solution, and various nanoscale features such as island-like and hole-like structures were achieved by changing weight ratio of the two immiscible polymers. The polymer-blended solutions were then individually spin-coated at 3000 rpm for 30 s onto the prepared Si substrates. Conclusions • Solvent-selective solubility of PLGA with different LA:GA ratio holds promise to separate PLGAs with varying LA:GA ratios. Prior to spin-coating of the solutions, silicon (Si) wafer substrates were cleaned by successive sonication in trichloroethylene, acetone, and isopropyl alcohol for 5 min each.

The UV curable PUA mixture consists of functionalized prepolymer with acrylate group, photoinitiator, and releasing agent for the surface activity, and the UV curing process induces cross-linking in the PUA mixture [17, 18]. However, in this work, PUA mostly remains at the polymer-substrate interface, which possibly originates from spinodal decomposition due to the differences of solvent evaporation rate for each polymer and polymer solubility in the common solvent. In addition, morphology of the PMMA/PUA blends can be easily controlled by changing composition (i.e., total concentration and weight ratio) of the blends. From academic labs to industrial applications users have been able to formulate … The molecular weight of PUA could be altered by adjusting a molecular weight of a functionalized prepolymer with acrylate group, and PUA with a similar molecular weight to PMMA (Mn = 11,500 g/mol) was used for this work. PMMA samples were solubilized at 0.1% (w/w) in THF and injected into the chromatograph (100 μL). For more than 50 years Hansen Solubility Parameters, HSP, have proven to be a powerful, practical way to understand issues of solubility, dispersion, diffusion, chromatography and more.

The study also revealed that variation in the temperature does not affect the miscibility of PMMA and PEG blends in THF significantly. 2.2.2 Preparation of PMMA solutions for spin-coating and plasma PMMA films PMMA (Mn = 11,500 g/mol, Mw/Mn = 1.08, Polymer Source Inc.) was used as received, and the UV curable PUA mixture was synthesized in accordance with the previous reports [17]. The effects of total concentration with the same weight ratio of PMMA : PUA (35 : 65) were examined using three solutions: (i) 7 g of 10 wt% PMMA mixed with 13 g of 10 wt% PUA, (ii) 7 g of 15 wt% PMMA mixed with 13 g of 15 wt% PUA, and (iii) 7 g of 20 wt% PMMA mixed with 13 g of 20 wt% PUA, respectively. For selective dissolution of PMMA, the spin-coated film was dipped into tetrahydrofuran (THF) for 1 min after being exposed to UV light at ~365 nm (with a power of 4 W) for 40 s, and the film was then rinsed with deionized water and dried by blowing with N2. Review articles are excluded from this waiver policy. THF (Merck) was distilled before use. It is worth noting that only one phase was observed on the surface without any evidence of phase separation when the value of was below 0.2 or above 0.8, due to the excess amount of one component in the blends. 1 Departamento de Ciencias Químicas, Facultad de Ciencias Exactas, Universidad Andrés Bello, Quillota 980, Viña del Mar, Chile. In addition, the PMMA/PUA blends with different weight ratios of PMMA : PUA were also examined for further evaluation of the mixing effects (see Section 2). The molecular weight was determined using the ... good solubility parameter for PMMA - 17.2 (J1/2 cm-3/2), which provides a difference greater than 1.5. Miscibility Gap. Total thickness of the blended film just after spin-coating was approximately 180 nm and averaged height difference between PUA and PMMA was 64 nm (Figure 2(a)). Various interaction parameters such as polymer-solvent and blend-solvent interaction parameters and heat of mixing have been calculated using the viscosity, density, and ultrasonic velocity data. Solubility of Potassium Acetate in Water, 2,2,2-Trifluoroethanol, Ethanol and Their Binary Mixtures at 288.15–333.15 K.

Island-like features completely disappeared at , and hole-like features with the diameter of ~500 nm were rather found as shown in Figure 4(c). After selective PMMA dissolution, the remaining film thickness was ~106 nm (Figure 2(b)). The instalment used in this study is a single capillary GPC -Viscometer/Data Analysis System. As the solvent evaporates during spin-coating, PGMEA in PMMA drains away prior to the PUA domains which are still swollen with PGMEA. Cyanoacrylate and acrylic [PMMA, MMA, etc] based polymers can get good bonding at the molecular level. The study also revealed that variation in the temperature does not affect the miscibility of PMMA and PEG blends in THF significantly. Various interaction parameters such as polymer-solvent and blend-solvent interaction parameters and heat of mixing have been calculated using the viscosity, density, and ultrasonic velocity data. PMMA samples were solubilized at 0.1% (w/w) in THF and injected into the chromatograph (100 μL). We are committed to sharing findings related to COVID-19 as quickly as possible. Note that the UV curing process was performed in the argon purged glove box, because oxygen plays a role as an inhibitor to photoinitiators. The results indicated the existence of positive interactions in the blend polymer solutions and that they are miscible in THF in the entire composition range. Padmanabhan P(1), Chavis M, Ober CK, Escobedo FA. Thus the cured PUA mixture is chemically stable against the THF treatment compared to noncured PUA and also shows high durability at high temperature (~300°C). Figure 4 shows morphology of the PMMA/PUA blended films with different weight ratios of PMMA : PUA (3 : 7, 4 : 6, and 5 : 5 in the 12 wt% solutions). The substrate exposure after film deposition also can be achieved by the selective dissolution without additional etching process, which may lead to further applications such as antireflection layers. Contact angles and surface tension data were measured to obtain the surface tension components of polyacrylamide (PAM).
