▎ 摘　　要

NOVELTY - The method involves modifying surface graphene by polyvinylpyrrolidone (PVP), ultrasonic dispersion to form a stable dispersion in water. The graphene dispersion is placed under 2.5MeV, 40mA electron accelerator irradiation and subjected to irradiation treatment to obtain a high-performance graphene dispersion. The high-performance graphene dispersion is dispersed into the latex, after curing, the high-performance graphene dispersion is formed by mold impregnation process, and then the far-infrared graphene condom is made after drying and curing. USE - Method for preparing far-infrared graphene condom used for preventing combination of sperm and eggs of human being during sexual intercourse. ADVANTAGE - The far infrared graphene condom has a unique far infrared function, the average far infrared emissivity is as high as 0.943 within the wavelength range of 5-14 microns, and the emitted far infrared rays are almost completely absorbed by a human body, so that microcirculation of reproductive organs of the human body is promoted, cells are activated, and local metabolism and immune functions are improved.
