Abstract

Summary: Nanostructured thermosetting materials were prepared by modification of an epoxy resin with 30 wt.-% epoxidized polystyrene-block-polybutadiene copolymer (PS-b-PepB). The copolymer self-assembles into a well-defined hexagonal nanoordered structure, of around 30-nm diameter, thus establishing its use as structure-directing agent to generate nanostructured thermosetting materials. The study confirms pathways towards tailoring interactions between thermosetting matrices and immiscible block copolymers by using the concept of functionalization to build nanostructured polymer matrices.
