摘要: Controlled phase separation in a polymer film, with subsequent morphology rearrangement on the micro-scale, provides novel perspectives smart materials. Based our experience supramolecularly compatibilised blends consisting of polystyrene and poly(butyl methacrylate), we demonstrate here physical segregation blend solid state by application an electrochemical stimulus. The thereby occurring changes film morphology, namely appearance voids grains, have been characterised atomic force microscopy spin coated Langmuir-Schaefer deposited films.
