PHOTOINDUCED PHASE SEPARATION IN TERNARY POLYMER BLENDS

摘要：

Introduction Photoinduced phase separation was studied for ternary polymer blends. Photocrosslink was combined with photopolymerization to generate and control the blend morphology by changing the irradiation intensity and blend composition. The resulting spinodal structure was frozen by chemical reaction, giving stationary periodic morphology.1) In this study, photoinduced phase separation was applied to ternary polymer blends without crosslink. As a result, various morphologies, particularly tricontinuous structure, were obtained by changing the mixture composition. Two polymers among the three components of the blend were labeled with different fluorescent probes. 3D morphology were observed and analyzed by using a laser scanning confocal microscopy (LSCM).
