Abstract
POSS is a class of unique building blocks for preparation of organic-inorganic nanocomposites. In this work, we investigated the influence of POSS microdomains on the properties of homogenous thermosetting blends of epoxy with poly(ethylene oxide). Herein, we first synthesized POSS-terminated poly (ethylene oxide) (PEO-POSS) and then incorporated it into epoxy to afford epoxy/PEO-POSS nanocomposites. Incorporation of PEO-POSS resulted in a microphase separation in the materials due to the self-assembly of PEO-POSS in the epoxy matrix. The influence of POSS microdomains on thermomechanical, surface and shape memory properties of nanocomposites were investigated in detail. Epoxy/PEO-POSS nanocomposites displayed higher glass transition temperature and surface hydrophobicity than epoxy/PEO blends with the same PEO content. Moreover, the formation of POSS microdomains could accelerate the shape recovery rate of the materials.
