摘　　要：利用等离子体引发的接枝反应对低密度聚乙烯(LDPE)薄膜进行表面改性处理,通过对接枝单体后LDPE薄膜表面单体接枝率的计算和表面接触角以及表面自由能的测量,系统地研究了单体浓度、反应温度、处理时间等对等离子体引发接枝反应的影响,并利用红外光谱、扫描电镜对接枝单体后薄膜表面的化学组成及表面结构进行了表征分析。The surface of LDPE film is modified by plasma-induced graft reaction. Treating effect grafting principle of hydrophilic monomer grafting induced by plasma onto the LDPE film is studied. Through the measurement of surface contact angle, grafting rate and surface free energy of LDPE film after grafting, the effect of monomer concentration, reaction temperature and treating time etc on the graft reaction are studied systematically. Moreover, IR and SEM are used to characterize the surface＇s chemical composition and morphological structure of the grafted samples.
