摘　　要：以多羟基结构的茶多酚作界面改性剂,制备了埃洛石纳米管/天然胶乳复合材料及二氧化硅/天然胶乳复合材料,研究了茶多酚对复合材料界面作用及力学性能的影响。结果表明,茶多酚分别能与埃洛石纳米管和二氧化硅形成氢键,改善了填料与橡胶基体间的界面作用。茶多酚改性天然胶乳复合材料的力学性能显著提高,其原因归因于复合材料界面状态的改善。Natural Rubber Latex （NRL）/halloysite nanotubes （HNT） composites and NRL/SiO2 composites were prepared by using tea polyphenols （TP） with multiple phenolic hydroxyls as novel in- terracial modier, respectively, and the effect of TP on interface and mechanical properties of the com- posites was investigated. FTIR results showed that the hydrogen bondings were formed between TP and HNT and SiO2, respectively, and interface between rubber and filler was modified. The mechanical properties of the composites modified with TP were significantly improved because of modification of the composites surface condition.
