Phase Segregation in Polystyrene—Polylactide Blends
Spun-cast hlms ot polystyiene (PS) blended with polylactide (PLA) weie visualized and chaiacten/ed using atomic foice micioscopy (AFM) and synchtoti on-based X-iay photoemission election micioscopy (X-PEEM) The composition ot the two polymets in these systems was deteimined by quantitative chemical analysis ot neat-edge X-tay absorption signals lecoided with X-PEEM The surface morphology depend...
متن کاملSurface segregation amplification in miscible polymer blends near criticality
– In atomic, small molecule or polymeric multicomponent materials, surface compositions naturally differ from the bulk because one component (or phase) will generally favor the surface region. Binary polymer blends represent a model system to investigate surface enrichment because segregation is enhanced by the small combinatorial entropy of mixing and amplified by chain connectivity (relative ...
متن کاملSurface Segregation Phenomena in Blends of Cellulose Esters
The principle of surface segregation and subsequent self-assembly of mixtures of molecules has been utilized to create cellulosic films that have properties characteristic of smart materials. This has been achieved by solventcasting a blend of cellulose propionate and an fluorine (F)-containing cellulose ester derivative. Evidence suggests that surface segregation of the F-containing species ta...
متن کاملSolubility and interfacial segregation of salts in ternary polyelectrolyte blends.
Solid Polymer Electrolytes (SPEs) consisting of ternary blends of charged polymer, neutral polymer, and plasticizer or salt have received much interest for their low volatility and high flexibility of polymers with ion-selective conductivity of the charge-carrying backbone. It has been shown that in these polyelectrolyte blends, where the dielectric constant is relatively low, ionic correlation...
متن کاملInterfacial segregation in polymer blends driven by acid-base interactions.
Infrared-visible sum frequency generation spectroscopy (SFG) was used to measure the interfacial concentrations of poly(methyl methacrylate) (PMMA)/polystyrene (PS) blends next to a sapphire substrate. The acid-base interactions of carbonyl groups of PMMA with the hydroxyl groups on the sapphire drive the interfacial segregation of PMMA next to the sapphire substrate. Using the shift of sapphir...
