    Abstract
  • The surface of HDPE and PC samples undergone transient shock pressure were investigated with ESCA and FT-IR, which show high oxygen/carbon ratio of 0.195∶1 and 0.266 ∶1 respectively, suggest that oxygen-containing groups are rich on the surface. The high pressure and temperature induced by shock are responsible for the chemical reaction directly. Large quantity of reactive sites and macromolecular radicals are formed while carbonization and oxydehydrogenation occurring. They then react with ambient oxygen on the spot, resulting in graft or substitution of the surface material.
