Wettability of the morphologically and compositionally varied surfaces prepared from blends of well ordered comb-like polymer and polystyrene

Tuning Surface Properties of Poly(methyl methacrylate) Film Using Poly(perfluoromethyl methacrylate)s with Short Perfluorinated Side Chains

“…It has been reported that the phase-separated structure of blends can be determined by various factors, such as the surface energy, solvent selection, and polymer–substrate interaction. , During spin coating, the polymer with lower surface energy and good solubility tends to aggregate at the air–polymer interface. , The vertical phase separation observed in the blend films, such as PPFPMA-50, PHFIPMA-50, and PHFBMA-50, composed of PFMMA in the upper part and PMMA in the lower part, might arise from the extremely large difference in their surface energies. The surface energies of the PFMMAs ranged from 10.1 to 12.6 mN/m, whereas that of PMMA was reported to be approximately 44.0 mN/m .…”

Polymer films with surfaces unmodified and modified by non-thermal plasma as new substrates for cell adhesion

“…Furthermore, because of the immiscibility of most polymers, the surface of polymeric blends usually presents segregated structures with domains predominantly composed of each individual polymer [24,25]. Recently, polymeric films of PS, PMMA and a 1:1 PS/PMMA blend were evaluated for cell adhesion using L929 mouse fibroblasts.…”

Surface phase separation, dewetting feature size, and crystal morphology in thin films of polystyrene/poly(ε-caprolactone) blend

“…Different factors such as film thickness [6,15], solvent [16,17], molecular weight [18], substrate [19][20][21], and blend composition [22][23][24] have also been examined extensively for amorphous polymer blends that involve only phase separation and dewetting process. If a crystalline polymer is introduced, unique structure may be constructed in the blend films due to the coupling of the phase separation, dewetting, and crystallization processes during spincoating.…”
