Abstract

original image

A novel ultrahigh-molecular-weight polyethylene/polymethacrylate semi- interpenetrating network is prepared using supercritical CO2. The mechanical properties of the UHMWPE material are vastly superior to the unmodified material and are related to the microstructure of these novel materials.
