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 T_g. The results show that under NR studies CO₂ can enhance the chain mobility at the polymer surfaces below the polymer bulk T_g.
