Polyaniline was synthesized by chemical oxidation polymerization, and polyaniline-silica (PANI-SiO2) nanocomposites were prepared by precipitation method. A reinforced PANI-SiO2/HNBR was obtained by filling the PANI-SiO2 composites into hydrogenated nitrile rubber (HNBR). The amino cations contained in acid-doped PANI can electrostatically attract SiO32−, so that SiO2 can grow directly on the surface of PANI, thus reducing the agglomeration of silica and improving the mechanical properties of reinforced rubber. The effect of PANI and PANI-SiO2 composites on mechanical properties of hydrogenated nitrile butadiene rubber was studied. The results show that PANI improves the dispersion of SiO2 in HNBR. When the PANI-SiO2 composite (PANI content of 2%) in PANI-SiO2/HNBR is 30 phr, the filler network is the weakest, and the dispersion of filler is the best in rubber, the maximum tensile strength of PANI-SiO2/HNBR is 30.31 MPa, which is 1.87 times that of SiO2/HNBR, the tear strength is 27.7 MPa, which is 129.4% of that of SiO2 reinforced packing with the same number of components. The hardness and elongation at break both increase. In addition, the permanent tensile deformation of PANI-SiO2/HNBR is also reduced.

聚苯胺复合二氧化硅填充氢化丁腈橡胶性能研究
采用化学氧化聚合法合成聚苯胺，采用沉淀法制备聚苯胺-二氧化硅(PANI-SiO 2 )纳米复合材料。将PANI-SiO 2复合材料填充到氢化丁腈橡胶(HNBR)中得到增强的PANI-SiO 2 /HNBR。掺酸聚苯胺中所含的氨基阳离子可以静电吸引SiO 3 2-，使SiO 2直接在聚苯胺表面生长，从而减少二氧化硅的团聚，提高补强橡胶的力学性能。PANI和PANI-SiO 2的作用研究了复合材料对氢化丁腈橡胶力学性能的影响。结果表明，PANI改善了SiO 2在HNBR中的分散。当PANI -SiO 2 /HNBR中的PANI-SiO 2复合材料（PANI含量为2%）为30份时，填料网络最弱，填料在橡胶中的分散性最好，PANI-的最大拉伸强度SiO 2 /HNBR为30.31 MPa，是SiO 2 /HNBR的1.87倍，撕裂强度为27.7 MPa，是相同组分SiO 2增强盘根的129.4%。硬度和断裂伸长率均增加。此外，PANI-SiO 2的永久拉伸变形/HNBR 也减少了。
