▎ 摘　　要

NOVELTY - Molybdenum diselenide-graphene co-modified poly(methyl methacrylate) photovoltaic module packaging film comprises 100 pts. wt. poly(methyl methacrylate) resin, 2-10 pts. wt. molybdenum diselenide nanoparticles, 1-5 pts. wt. graphene, 0.5-1 pts. wt. UV light absorber, 0.1-0.5 pts. wt. light stabilizer, 0.2-1.2 pts. wt. antioxidant, 0.2-3 pts. wt. tackifier, 0.01-6 pts. wt. crosslinking agent, 0.05-1 pts. wt. initiator, and 0.1-0.5 pts. wt. silane coupling agent. USE - Used as packaging film. ADVANTAGE - The packaging film has high insulating property, weather resistance property, and low light attenuation rate. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing molybdenum diselenide-graphene co-modified poly(methyl methacrylate)photovoltaic module packaging film comprising (i) taking poly(methyl methacrylate) resin, molybdenum diselenide nanoparticles, graphene, UV absorbers, light stabilizer, antioxidant, thickener, crosslinking agent, initiator, and silane coupling agent, allowing to stand; and (ii) adding step (i) taken raw materials to high-speed mixer, premixing, to obtain premix, feeding premix to a single screw castor, casting, to obtain packaging film, where the speed of high speed mixer is 500-1500 revolutions/minute, and mixing time is 10-50 minutes.
