Thermo-mechanical properties of polystyrene-based shape memory nanocomposites

Author affiliations

Abstract

Shape memory nanocomposites were fabricated using chemically cross-linked polystyrene (PS) copolymer as a matrix and different nanofillers (including alumina, silica and clay) as the reinforcing agents. Their thermo-mechanical properties and shape memory effects were characterized. Experimental results revealed that the nanofillers provide significant reinforcement of the PS, and the nanocomposites exhibit better thermal and mechanical properties, including shape memory properties, than unreinforced PS. Both experimental and theoretical analyses have shown that the rod-shaped clay nanofillers offer better reinforcement than spherical nanoparticles, because of their high aspect ratio and ability to reinforce in multiple directions.
