摘要

Polymer surface engineering under subcritical CO2 at low temperature was discussed. Neutron reflectivity (NR) and atomic force microscopy (AFM) were used to investigate the surface dynamics of polymer under CO 2. It was found that there is a rubbery layer of up to a hundred nanometers thick at the surface where the glass transition temperature (T g) was lower than that in the bulk and CO2 dramatically reduced the surface Tg. The results show that under NR studies CO2 can enhance the chain mobility at the polymer surfaces below the polymer bulk Tg.
