一种制备铝基复合材料疏水导线的方法

A Preparation Method of Aluminum Matrix Composites’ Hydrophobic Wire

利用累积复合轧制法(ARB方法)制作出不同混合比例的4043铝/石墨烯纳米复合材料(累积复合轧制法可被看作是若干个单道次压下量为50%的轧制复合的往复循环),测试得到了不同比例的4043铝/石墨烯复合材料的电导率和静态接触角,发现随着石墨烯掺杂的比例增大,石墨烯/铝复合材料的静态接触角明显提高,电导率略有降低。

We have made grapheme sheets/4043 aluminum nanocomposites of different mixing ratios by using accumulative roll bonding (ARB) method. ARB method can be regarded as a number of single channel reductions of 50 percent reciprocating cycle. The electrical conductivity and the static contact angle of the different proportions of graphene sheets/4043 aluminum composites were obtained by testing. We have found that as the proportion of graphene doping increases, the static contact angle of graphene sheets/aluminum composites significantly increases, and conductivity slightly decreases.
