NOVELTY - A radiation-proof computer film comprises 60-80 pts. wt. polyethylene terephthalate film, 10-30 pts. wt. graphene oxide-barium-silver nanocomposite, 1-5 pts. wt. gamma -aminopropyltrimethoxysilane, 1-5 pts. wt. gamma -mercaptopropyltriethoxysilane, 3-10 pts. wt. plasticizer, 2-10 pts. wt. antifoaming agent, 1-5 pts. wt. film forming agent and 30-60 pts. wt. deionized water. The plasticizer is di(2-ethylhexyl)phthalate, dioctyl phthalate, di-n-octyl phthalate, butyl phthalate, di-octyl phthalate, dicyclohexyl phthalate, dibutyl phthalate, diisobutyl phthalate, dimethyl phthalate, diethyl phthalate and/or diisononyl phthalate. The antifoaming agent is emulsified silicone oil, high carbon alcohol fatty acid ester complex, polyoxyethylene polyoxypropylene pentaerythritol ether, polyoxyethylene polyoxypropanolamine, polyoxypropylene glyceryl ether, polyoxypropylene polyoxyethylene glyceryl ether or polydimethylsiloxane. The film forming agent is double bond-containing silane film forming agent. USE - Radiation-proof computer film. ADVANTAGE - The radiation-proof computer film has excellent antibacterial performance. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of radiation-proof computer film, which involves placing polyethylene terephthalate film in acetone solution of gamma -aminopropyltrimethoxysilane, irradiating with ultraviolet light for 1 hour, placing polyethylene terephthalate film in anhydrous xylene solution of gamma -mercaptopropyltriethoxysilane, removing, washing, drying, dissolving graphene oxide-yttrium silver nanocomposite in anhydrous ethanol, ultrasonically dispersing, adding film forming agent and defoaming agent, stirring constantly, obtaining stable transparent sol, immersing surface-modified polyethylene terephthalate film in transparent sol for 3-5 hours, adding plasticizer and deionized water, continuously soaking for 5-10 hours, removing, drying and cutting.
