| 摘 要： | 研究了在空气中电子束辐照所引起的ＨＤＰＥ分子结构变化以及辐照对ＨＤＰＥ亲水性的影响”。结果表明,通过电子束辐照可在ＨＤＰＥ分子链上引入含氧极性基团,使的表面自由能增大,极性增强,与水的接触角减小。辐照ＨＤＰＥ的分子量降低,分子量分布变窄。

| 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. |

| Keywords: | electron beam irradiation high density polyethylene hydrophilicity |
