Preparation method of transparent and colorless composite latex condom with high insulating property and high strength

The invention relates to the fields of composites and medical instruments and specifically relates to a preparation method of a transparent and colorless composite latex condom with high insulating property and high strength. The preparation method comprises the steps: connecting a panel covering transparent graphene with an electrode holder, spraying a polyvinylpyrrolidone glue solution on the panel, and then, placing the panel into an insulated vessel holding water; electrifying for electrolysis, meanwhile, shattering and stripping graphene adsorbed by polyvinylpyrrolidone under the assistance of ultrasound, and finally, uniformly dispersing graphene into water; and concentrating the solution to form composite gel, then, circulating the former processes, finally, stirring and dispersingthe composite gel into vulcanized natural latex to obtain a composite latex emulsion, and then, preparing a pure transparent graphene composite condom. The graphene composite condom prepared by usingthe preparation method is
