“…Some novel designs of nanomaterials also were applied in developing the UV shielding composite films, such as hybrid organic‐inorganic films . In addition, polymers, such as poly (vinyl chloride) (PVC), Poly(vinyl alcohol) (PVA), Poly(ethylene terephthalate) (PET), Poly(ethylene glycol‐co‐1,4‐cyclohexanedimethanol terephthalate) (PETG), poly(lactic acid), has been used widely as UV shielding substrates. Whereas the above‐mentioned polymers are generally refined from the nonrenewable petroleum resource.…”
