Novel condom based on graphene modification technology and production method thereof

Abstract

The invention belongs to the technical field of general medical and sanitary products, and particularly relates to a novel condom based on a graphene modification technology and a production method thereof. The novel condom is added with graphene oxide and functionalized graphene by 0.1-25%. The graphene oxide or the chemically-modified functionalized graphene is dispersed into a condom material with natural latex as a base material through an aqueous phase or an emulsion according to demand, thereby producing the condom according to processes in the prior art. The condom holds a high toughness even if the minimum thickness reaches 15 [mu]m, so that use requirement of the condom is satisfied. The condom is increased by 15-40% in strength when compared with original natural latex materials. Because that the graphene is low in breathability and has material composition effects, the condom is less in micro-pores so that virus penetrating probability is greatly reduced. The heat conductivity coefficient of the composite material is increased by 10-20 and the condom is improved in body feel.

Description

technical field [0001] The invention belongs to the technical field of common medical and sanitary products, and in particular relates to a novel condom based on graphene modification technology and a manufacturing method. Background technique [0002] Condoms have two functions, one is to effectively prevent pregnancy, and the other is to prevent the spread of diseases. Most of the existing condoms are made of natural latex. Natural latex has intrinsic pores of 5 μm, which can effectively block sperm, and can also effectively block most bacteria and some viruses. However, due to the contradiction between the effect of contraception and virus isolation and the physical sensation, the thicker the condom is, the better the barrier against bacteria and viruses is, but the physical sensation becomes worse. When the thickness is thinner, the body feels better, but the condom is easy to break, and bacteria and viruses are easy to spread through the micropores, resulting in poor p...

AI Technical Summary

Problems solved by technology

However, due to the contradiction between the effect of contraception and virus isolation and the physical sensation, the thicker the condom is, the better the barrier against bacteria and viruses is, but the physical sensation becomes worse.

When the thickness is thinner, the body feels better, but the condom is easy to break, and bacteria and viruses are easy to spread through the micropores, resulting in poor protection against sperm and diseases.

When the thickness becomes thinner, some viruses with smaller diameters, such as HIV, hepatitis B virus, human papillomavirus, genital herpes simplex virus, etc., have unsatisfactory blocking effect
