Example Embodiment
[0042] Example 1
[0043] A preparation process of graphene nano composite material includes the following steps:
[0044] In the first step, weigh the raw materials according to the following parts by weight: 50 parts of bisphenol A diglycidyl ether, 11 parts of diethyl toluene diamine, 2 parts of modified graphene oxide, and 100 parts of absolute ethanol;
[0045] In the second step, after mixing bisphenol A diglycidyl ether and diethyltoluenediamine, stir vigorously at 100°C for 15 minutes to obtain a light yellow liquid epoxy resin pre-compound;
[0046] The third step is to add the epoxy resin pre-composite to absolute ethanol, stir and mix at 300r / min for 26 minutes at room temperature, and then degas it in a vacuum oven at 110°C for 30-40 minutes to obtain the epoxy resin pre-composite Mixture with ethanol;
[0047] The fourth step is to add the modified graphene oxide to the mixture of the epoxy resin pre-composite and ethanol, sonicate at room temperature for 40 minutes to for...
