POLYMER DISPERSED LIQUID CRYSTALS : LIQUID CRYSTAL / POLYMER COMPOSITES AS ELECTRO ACTIVE MATERIALS

摘要

In spite of the role of gelation on the phase separation, our experiments highlight the effect of the N-I transition compared to the cure temperature.rnFor cure temperatures higher than T_(N-I)i (neat LC), phase separation proceeds by a thermal process. For cure temperatufes quite lower than T_(N-I) (neat LC), phase separation may proceed by a chemical quench. In the former case, morphology depends on the cooling rates ; in the latter case, morphology may be fixed by gelation.
