[0036] refer to figure 1 , according to an embodiment of the present invention, the preparation method of the composite material includes the following steps:
[0037] Surface laser treatment of liquid metal substrates to form tiny holes;
[0038] Surface treatment of liquid metal substrates with fine pores with liquid metal wetting agents;
[0039] Injection-molding the liquid metal base material and plastic treated with the liquid metal wetting agent to obtain a composite material integrating liquid metal and plastic;
[0040] Wherein, the liquid metal wetting agent contains an organic modifier for improving the difference in surface tension coefficient between the liquid metal substrate and the plastic.
[0041] The materials involved in the practice of the method of the present invention are as follows.
[0042] 1. Liquid metal: It can be a shaped liquid metal substrate prepared by copper mold suction casting method, liquid quenching method, sputtering method, spray gun...
