The invention discloses a
graphene modified natural
emulsion preparation method and a high barrier
condom. The
graphene modified natural
emulsion preparation method and the high barrier
condom have the beneficial effects that firstly
graphene and a dispersing agent mixed liquor are mixed, ground and stirred and then the product is mixed in a natural
emulsion aqueous solution, so that graphene can be uniformly dispersed in emulsion and the strength of a natural emulsion
composite material is improved; meanwhile, the number of micropores is smaller due to the graphene / emulsion composite action, thus greatly reducing the
virus penetration probability; the thickness of the graphene
condom can be 5-80mu m, so that the use requirements of the condom can be met; dense high barrier packing
layers are formed by the composite crosslinked nano-packing technology, so that the natural gaps among molecules are reduced; therefore not only can HIVs be blocked but also
hepatitis B viruses,
hepatitis C viruses, human
papilloma viruses, and the like, and most harmful
bacteria, which are smaller than the HIVs, can not pass through the micropores.
