In this work, a distinguished hydrothermal treatment succeeded in modifying aramid nanofibers (ANFs) with the help of mixed acid, and the hydrothermal-treated ANFs (hANFs) were regarded as a reinforcement agent to be introduced into styrene-butadiene rubber (SBR) via latex co-agglutination treatment. The enhanced comprehensive behaviour of SBR/hANFs composites induced by π-π stacking interaction between hANFs and polymer chains were investigated in details. With respect to virgin SBR, it was found that the temperature at maximum rate of degradation, tear strength and tensile strength of composites with adding 7 phr (parts per hundred rubber) hANFs significantly improved by 14 °C, 148 % and 215 %, respectively. The incorporation of hANFs also endowed SBR with greatly enhanced solvent resistance.

在这项工作中，杰出的水热处理成功地通过混合酸对芳纶纳米纤维（ANFs）进行了改性，水热处理的ANF（hANFs）被认为是一种增强剂，可通过以下方法引入丁苯橡胶（SBR）中乳胶共凝集治疗。详细研究了由hANFs和聚合物链之间的π-π堆积相互作用引起的SBR / hANFs复合材料增强的综合性能。对于纯SBR，发现添加7 phr（每百份橡胶的份数）hANF的复合材料在最大降解速率，撕裂强度和拉伸强度下的温度分别显着提高了14°C，148％和215％。 。hANF的加入也使SBR的耐溶剂性大大提高。
