▎ 摘　　要

NOVELTY - UV-resistant nanocomposite coating comprises a polyaniline (PANI)/graphene oxide (GO) nanocomposite comprising GO nanosheets coated with PANI, where the PANI/GO nanocomposite dispersed into a binding matrix. USE - The coating is useful for preparing weathering-resistant nanocomposite coating for cladding panels. ADVANTAGE - The coating: is eco-friendly, cost-effective and have a longer service life; and that may be anti-scratch, easy to clean and long-lasting. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing the coating comprising: either obtaining a binder mixture by mixing at least one of an epoxy acrylate resin and a urethane acrylate resin with at least one of dibasic esters and siloxane, obtaining a nanocomposite/binder dispersion by mixing a PANI/GO nanocomposite with the binder mixture, obtaining a first mixture by adding at least one of fumed silica and bentonite and at least one of silica and polyolefin waxes to the nanocomposite/binder dispersion under constant stirring and reaching an average particle size of less than 10 microm by constantly stirring the fumed silica and bentonite, the silica and polyolefin waxes and the nanocomposite/binder dispersion and obtaining coating by adding at least one of azobisisobutyronitrile, trimethylolpropane triacrylate and trimethyl benzoyl diphenyl phosphine oxide to the first mixture at room temperature in the absence of sunlight; or obtaining a binder mixture by mixing a resin with a dispersant, obtaining a nanocomposite/binder dispersion by mixing a PANI/GO nanocomposite with the binder mixture, obtaining a first mixture by adding a rheology modifier and a matting agent to the nanocomposite/binder dispersion under constant stirring and reaching an average particle size of less than 10 microm by constantly stirring the rheology modifier, the matting agent and the nanocomposite/binder dispersion and obtaining the coating by adding an initiator to the first mixture at room temperature in the absence of sunlight.
