Abstract

Summary: Inorganic-organic nanostructured thermosetting composites based on poly(styrene-block-ethylene oxide) (SEO) block copolymer used as templating agent and titanium dioxide (TiO2) nanoparticles synthesized via sol-gel were prepared. The morphologies generated in the binary and ternary epoxy-based systems were studied using atomic force microscopy (AFM). Ternary systems showed good dispersion of synthesized nanoparticles and simultaneously maintained nanostructure order of the cured block copolymer/epoxy-based system due to self-assembly of SEO block copolymer. Transparent multifunctional advanced thermosetting materials with tuneable properties controlled varying the ratio between inorganic and organic components was successfully designed.
