A Preparation Method of Aluminum Matrix Composites' Hydrophobic Wire

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.
