〈p〉The needle-like TiO〈sub〉2〈/sub〉 obtained by hydrothermal treatment combines with Graphene by adding cetyltrimethylammonium bromide (CTAB) as auxiliary dispersant. On this basis, the needle-like TiO〈sub〉2〈/sub〉/Graphene composite conductive material was prepared which is increasing the compatibility of conductive Graphene. The growth mechanism of the needle-like TiO〈sub〉2〈/sub〉/Graphene was discussed and supported by scanning electron microscopy, transmission electron microscopy and other test methods. Experimental results show that hydrothermal temperature has a great influence on the formation of needle-like TiO〈sub〉2〈/sub〉. The quick electron transportation properties between TiO〈sub〉2〈/sub〉 and Graphene make the TiO〈sub〉2〈/sub〉/Graphene have excellent conductive ability. Needle-like TiO〈sub〉2〈/sub〉 can facilitate electron transport on the layer of Graphene. The three-dimensional mesh structure formed by crisscross of needle-like TiO〈sub〉2〈/sub〉 is attached to the Graphene surface by the auxiliary effect of CTAB, is forming a conductive network to increase the transmission rate of electrons, so that the TiO〈sub〉2〈/sub〉/Graphene is endowed with good electrical conductivity. Finally, the resistivity of TiO〈sub〉2〈/sub〉/Graphene is as low as 1.655 × 10〈sup〉−3〈/sup〉 Ω m at 7 wt% Graphene, which conforms to the electrical conductive standard of the materials prepared by the factory.〈/p〉
