In this work, a distinguished hydrothermal treatment succeeded in modifying aramid nanofibers (ANFs) with thehelp of mixed acid, and the hydrothermal-treated ANFs (hANFs) were regarded as a reinforcement agent to be introducedinto 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 tensilestrength of composites with adding 7 phr (parts per hundred rubber) hANFs significantly improved by 14 oC, 148 % and215 %, respectively. The incorporation of hANFs also endowed SBR with greatly enhanced solvent resistance.
