【Abstract】 The effect of electron beam irradiation conditions on the structure of HDPE and its hydrophilicity were studied. The experimental results show that polar groups (mainly carbonyl group) are introduced into the molecular chains of HDPE during electron beam irradiation, the polarity of HDPE is thus increased. Irradiation also causes the degradation of HDPE, its molecular weight is decreased, and molecular weight distribution becomes narrow.更多还原
