摘要

用电子束引发预辐照接枝的方法，在高密度聚乙烯（High density polyethylene，HDPE）薄膜上接枝甲基丙烯酸缩水甘油酯（Glycidyl methacrylate，GMA），制备了含有高活性环氧基团的聚合物膜。详细研究了单体浓度、反应温度和时间以及吸收剂量等因素对接枝率的影响规律。应用傅立叶变换红外光谱（FT–IR）、差示扫描量热仪（DSC）、原子力显微镜（AFM）研究了接枝物的组成、热性能和表面形貌。FT–IR测试表明接枝物为HDPE–g–GMA共聚物；接枝膜的熔融温度,T,m,以及修正后HDPE组分Δ,H,f (HDPE), 均随着接枝率的增大而降低，原因归结于HDPE接枝后结晶度降低。HDPE–g–GMA膜的AFM图像显示其表面粗糙度增加，进一步证明膜表面发生了接枝反应。

Abstract

Glycidyl methacrylate (GMA) was grafted onto HDPE membranes by pre-irradiation method with 1.8 MeV E-beams, and a kind of membranes having reactive epoxy groups was successfully synthesized. Effects of monomer concentration, reaction temperature and time and irradiation dose on the grafting yield were studied. Composition, thermo-property and surface morphology of the grafted membranes were studied by FTIR, DSC and Tapping-mode AFM, respectively. The FTIR measurements proved the synthesized copolymer is HDPE-g-GMA. The DSC results indicated the grafted HDPE’s melting temperature (,T,m,) and the heat of fusion (Δ,H,f (HDPE),) which was reduced with increasing grafting yield. The AFM images indicated that surface of the HDPE-g-GMA membranes was rougher than the virgin HDPE.
