2、聚偏氟乙烯(PVDF)/聚醚型热塑性聚氨酯弹性体(PUR–T)复合材料,初步探讨了单一增容剂(KH–560或ATBN)含量、复配增容剂含量与比例及成膜温度等条件对PVDF/PUR–T复合材料力学性能的影响,深入研究了复合材料的结晶性能、热稳定性能和亲/疏水性能。结果表明,与单一增容剂相比,复配增容剂的引入明显提高了复合材料的力学性能,并且当复配增容剂添加量为10%,复配比KH–560/ATBN=3/1,成膜温度为50℃时,其与PVDF/PUR–T基体间的界面粘结性明显得到改善,改性后复合材料断裂伸长率达到273%。PUR
3、–T与复配增容剂的加入抑制了PVDF的结晶,复合材料的结晶度降低,但仍具有良好的热稳定性能,且疏水性得到提高。关键词:聚偏氟乙烯;热塑性聚氨酯弹性体;增容剂;复合材料;力学性能中图分类号:TQ323.8文献标识码:A文章编号:1001-3539(2016)04-0102-05InfluenceofCompatilizeronPropertiesofPVDF/PUR-TComposites11112ZhangMin,YanFei,ZhangLu,LiChengtao,GaoWei(1.KeyLaboratoryofAuxi
