摘要

Abstract

The effects of film thickness and composition ratio on the morphology evolution of polystyrene (PS)/poly(vinyl methyl ether) (PVME) blend thin films were investigated. Diverse morphology evolutions including droplet-matrix structure

hole emergence

bicontinuous structure formation

percolation-to-droplet transition could be observed under annealing in two-phase region

depending on film thickness and composition ratio. The mechanism for these morphology variations was related to the complex effects of phase separation

dewetting and preferential wetting. The comparison between the thickness of bottom PVME layer and the twice of gyration radius 2

(PVME) played a dominant role in morphology control. Only when the PS/PVME film had specific film thickness and compositional symmetry

phase separation and dewetting could happen in sequence.
