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.

Using KOH and WO3 as raw materials, K10[H2W12O42] · 10H2O nanorod was successfully synthesized via controlling the pH value and the K/W mole ratio of hydrothermal system. The structure and morphology of the samples were characterized by XRD, SEM, TEM, HRTEM and selected area electron diffraction (SAED). The size of K10[H2W12O42] · 10H2O nanorod was about 300 nm in width and 3–10 µm in length. The nanorod consisted of self-assembly nanowires with about 10 nm in width. Moreover, the electrochemical performance of K10[H2W12O42] · 10H2O as anode material was investigated, indicating that the as-prepared sample electrode possessed a certain ability of lithium ion insertion/extraction, and exhibited a high initial discharge capacity of 310 mAh g-1.
