Paper Abstract

In this project, shape memory polystyrene foam was fabricated from shape memory polystyrene and ethyl acetate/n-hexane as physical foaming agent based on suspension polymerization method. The foam of uniform pore structure with porosity ranging from 36%~45% have been made successfully. Both shape memory properties and physical properties were characterized. Shape memory polystyrene foam exhibited good shape memory properties-- completely recovery the initial undeformed shape after multiple cycles. The higher thermal stability was achieved compared with pure shape memory polystyrene. The glassy state property of the foam was increased from 75°C to 85°C as the content of filler increased from 0 to 30%.
