The phase separation of PMMA/PUA blend was well-driven via solvent evaporation during spin-coating. Solvent parameters, including Lewis basicity, solubility parameters, and a hydrophobicity parameter, were used to discuss the change in the PMMA solubility … However, no apparent domains were left on the noncured film after dissolving in THF as shown in Figure 2(c), which implies that the noncured PUA domains are removed with PMMA together during the THF treatment. 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 compound is classified as heterocyclic compound, specifically a cyclic ether.It is a colorless, water-miscible organic liquid with low viscosity.It is mainly used as a precursor to polymers. In addition, theHildebrand solubility parameter, perhaps the most widely applicableof all the systems, includes such variations as the Hildebrandnumber, hydrogen bonding value, Hansen parameter, and fractionalparameter, to name a few… O 15 wt-% H. 2. Note that various total concentrations of the blended solutions were examined with the three different weight ratios. Cyanoacrylate and acrylic [PMMA, MMA, etc] based polymers can get good bonding at the molecular level. 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: A miscibility gap occurs when the substances being mixed exist at more than one phase and as a result experience a gap in miscibility.

Being polar and having a wide liquid range, THF is a versatile solvent RESEARCH FRONT. The water solubility of THF is complex. (THF) has been investigated by viscosity, density, refractive index, and ultrasonic velocity studies. As the solvent evaporates during spin-coating, PGMEA in PMMA drains away prior to the PUA domains which are still swollen with PGMEA. We anticipate that these controllable structures originating from the phase separation will be applied to various engineering fields such as soft lithography. The solvents that dissolve PMMA are dimethylformamide (DMF) and Diethyl carbonate (DEC). 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. Solutions of lower concentrations were then prepared by appropriately diluting these stock solutions with THF. The polymer-blended solutions with different concentrations were prepared to evaluate the effects. 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.

Instant access to the full article PDF. However, various interactions, such as polymer-polymer and polymer-surface interactions, cause complexity and difficulty in control of the selective dissolution and fabrication of desired structures. The densities of the polymer solutions in THF … Particularly, it is well known that domain structures and surface topography strongly depend on various polymer interactions (i.e., polymer-polymer and polymer-surface interactions) in the blended films, and the relative solubility of polymers in a common solvent can play a crucial role in determination of surface morphology [6]. See: Pubchem; T = 20 °C unless specified otherwise. O * * n O O H H O Transmittance [%] The study also revealed that variation in the temperature does not affect the miscibility of PMMA and PEG blends in THF significantly. 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. After the THF treatments, the heights of the cured PUA were found to be ~61 nm (for 10 wt%), ~119 nm (for 15 wt%), and ~170 nm (for 20 wt%), respectively (Figures 3(d)–3(f)). Phase separation in spin-coated films is normally explained by various mechanisms, such as polymer-surface interactions, surface energy differences between polymers, and fast solvent evaporation of one component in polymer blends [20, 21]. The cross-linked PUA in the polymer-blended films provides strong chemical stability in the solvents such as THF, and thus target materials for dissolution can be selectively available via a simple curing process. It is concluded that the product PMMA particles, derived from the PMMA-acetone dilute solution, have a smaller particle size than those from the PMMA-THF dilute solution. Spin casting the PMMA/PUA blends in propylene glycol monomethyl ether acetate (PGMEA) was accompanied with phase separation, and PUA was subsequently cross-linked under UV radiation.

O * * n O O H H O Transmittance [%] I tried to dissolve it in THF but it didn't dissolve properly even after heating at 40. 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. 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 Consequently, the solvent in PMMA is quickly depleted in the spin-coating process, which leads to elevation of the PMMA domains onto the PUA-rich domains. This work was supported by a research grant of Pukyong National University (Year 2014). checked visually for a qualitative determination of solubility and scored “0” – “2” to indicate no dissolution (0), partial dissolution (1), and full dissolution (2). 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. The presence of hydrogen bonding in the blends in the solid state has also been indicated by FTIR studies.". Although the solubility of PUA in THF is relatively low, the noncured PUA can be dissolved in THF due to the polymer interactions between PUA and PMMA . 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. Although the solubility of PUA in THF is relatively low, the noncured PUA can be dissolved in THF due to the polymer interactions between PUA and PMMA [12].
