Abstract

The invention relates to the field of composite materials and medical appliances, and particularly provides a method of producing a stable and light-colored high-heat-conductive and high-isolating condom from graphene laminating hexagonal nano-lamella boron nitride compounded latex. The method includes the steps of: a) laminating and compounding graphene treated in an electric field and modified hexagonal nano-lamella boron nitride to form a stable dispersion liquid, pH being 4.5-7; b) dispersing the stable dispersion liquid in latex to compound the components with solid mass ratio being 0.005-1 wt%, thereby finally producing the condom. Being different from common graphene condoms, the condom in the invention has a stable transparent color and is not liable to have defects, such as graying, darkening, and poor weather-resistant stability, due to deterioration of graphene. The graphene is laminated with the nano-lamella boron nitride which is also called white graphene, so that tensile strength, flexibility and heat conductivity of latex are improved and permeation of virus liquid is effectively isolated, thereby producing ultrathin, high-heat-conductive and high-isolating condoms.

Description

technical field [0001] The invention relates to the field of composite materials and medical devices, in particular to a method for preparing stable light-colored condoms with high thermal conductivity and high insulation by bonding graphene to hexagonal nano-sheet boron nitride composite latex. Background technique [0002] The vast majority of condoms are made of natural latex, which has many advantages and some disadvantages, such as: latex naturally forms micropores with diameters ranging from hundreds to thousands of nanometers. [1] , Some AIDS (maximum diameter: 120nm), hepatitis B (maximum diameter 42nm), human papilloma (maximum diameter 55nm), etc. may have the chance of spreading through micropores. [0003] Both graphene and hexagonal nanosheet boron nitride are two-dimensional nanomaterials with extremely high sheet diameter / thickness ratio, good toughness and impermeability [2] . On the one hand, all modified graphene, graphene oxide and reduced graphene will ...
