Hydroxy-Methylated Lignin for the Preparation of UV Shielding PVA/Lignin Films.

ABSTRACT: Traditional plastic films have caused serious environmental issues due to "white pollution". This study isolates lignin from cottonseed hulls to explore alternatives to plastic films. Using both cottonseed hull lignin and commercially sourced white lignin as raw materials, we performed hydroxy-methylation modification via physical and chemical cross-linking to obtain hydroxy-methylated cottonseed hull lignin and hydroxy-methylated white lignin, resulting in hydroxy-methylated lignin with improved hydrophilicity. Additionally, we prepared a hydroxy-methylated lignin/poly-(vinyl alcohol) composite film loaded with sorbitol and incorporated glycerol as a plasticizer to further enhance the mechanical properties of the composite material. The results indicate that the performances of both cotto
