Nanostructured organic/inorganic materials based on sol-gel processes in sulfonated poly[styrene-co-(ethylene-butylene)-co-styrene] (SEBS) block copolymers

摘要

The phase separated morphologies of hard/soft block copolymers (BCPs) allow for tailoring organic/inorganic hybrid materials having well-defined nanostructures. Mauritz et al. have used poly(styrene-b-isobutylene-b-styrene) block copolymers (BCP) as morphological templates in the sense of sol-gel polymerizations of hydrolyzed tetraethylorthosilicate (TEOS) exclusively within sulfonated polystyrene (sPS) block domains. A condensed silicate network can be formed that conforms to the geometry of the PS domains. We are concerned with influence of silicate nanophases on the thermal, mechanical and molecular transport properties of the BCP.
