摘要
聚丙烯是一种性能优良的热塑性通用树脂,具有透明、质轻、耐热、电绝缘和良好的加工性能,广泛应用于纤维制品、汽车零部件、输送管道和包装材料等领域.与环氧树脂等极性材料相比,共混法制备的复合材料界面相容性差,因此研究聚丙烯复合材料的界面增强尤为重要.文章分析近十年有关聚丙烯复合材料界面增强研究,概述了五种界面黏接机理,包括化学键合理论、机械互锁理论、界面扩散理论、界面浸润理论和界面结晶理论,对施胶剂/涂层处理、纳米材料"多尺度"修饰填料表面,通过分子自组装作用、诱导界面结晶的聚丙烯基体改性等界面增强方法进行评述,最后展望了聚丙烯复合材料界面研究的未来机遇和挑战.
Abstract
Polypropylene is a kind of excellent thermoplastic general purpose resin,which has transparent,light weight,heat resistance,electrical insulation,and good processing properties,and is widely used in fiber products,auto parts,pipeline,packaging materials,and other fields.Compared with epoxy resin and other polar materials,the interfacial compatibility of polypropylene composites is poor,so the study of interfacial strengthening of polypropylene composites is particularly important.This paper analyzes the research on interface strengthening of polypropylene composites in ten years,and summarizes five interface bonding mechanisms,including chemical bonding theory,mechanical interlock theory,interface diffusion theory,interface infiltration theory,and interface crystallization theory.The interfacial enhancement methods such as sizing agent/coating treatment,'multi-scale'modification of filler surface by nano-materials,molecular self-assembly,and polypropylene matrix modification that induces interfacial crystallization are reviewed.Finally,the future opportunities and challenges of interfacial research on polypropylene composites are prospected.
