摘要
本文通过红外光谱、与水的接触角以及力学性能测试等研究了空气中紫外辐照ＨＤＰＥ 官能化及其增容作用。结果表明，紫外辐照能有效地在ＨＤＰＥ 分子链上引入 Ｃ Ｏ 基团，随辐照时间增加，ｕＨＤＰＥ 的 Ｃ Ｏ 基团含量提高，与水的接触角下降；在一定条件下制得的ｕ ＨＤＰＥ 对ＨＤＰＥ／ＰＣ 共混体系有增容作用，其共混物的拉伸强度、断裂伸长率和缺口冲击强度比未增容的都有提高。
s HDPE could be functionalized by ultraviolet irradiation in air.The compatibility of uHDPE was evaluated with measurements of its mechanical properties and contact angle with water.It was found that c=0 group could be introduced on to the chain effectively.The longer irradiation time,the more c=0 and the smaller contact angle.Proper treated uHDPE behaved as compatibilizer in HDPE/PC blend and enhanced its tensile strength,elongation at break and Izod notched impact strength.
