| 摘 要： | 通过FT-IR、凝胶分析、水接触角和力学性能测定，研究了空气中不同环境温度下紫外辐照官能化HDPE的结构变化、亲水性和紫外辐照官能化HDPE对HDPE／PVA共混体系的增容作用。在相同的紫外辐照时间下，随环境温度提高，引入HDPE分子链的C=O和C--O含氧基团的含量增加，其HDPE的亲水性变好，但它的凝胶含量也有所增加。与HDPE／PVA体系相比，经过紫外辐照官能化HDPE增容的HDPE／PVA体系的拉伸强度和缺口冲击强度均得到提高。

| Abstract: | The structure, hydrophilicity of high density polyethylene (HDPE) functionalized by ultraviolet irradiation at different environmental temperature in air, and compatibilization of the functionalized HDPE in HDPE/polyvinyl alcohol (PVA) blends were studied through FT-IR, gel analysis, water contact angle and mechanical properties measurements. Oxygen-containing groups such as C-O and C=O were introduced onto HDPE chains after the ultraviolet irradiation in air. The oxygen-containing groups content, gel content and hydrophilicity increase with increasing the environmental temperature. The compatibilization of the functionalized HDPE increases with the environmental temperature; Compared with HDPE/PVA blend, the tensile yield strength and notch impact strength of HDPE/PVA blends compatibilized functionalized HDPE are increased. |
