Chitosan (CTS) exhibits notable moisturizing and film-forming capabilities, whereas nano selenium (SeNPs) demonstrates antioxidant and antibacterial properties. In the present study, a CTS/Se film-forming agent was prepared by dissolving CTS, glycerol, and SeNPs in 1% (v/v) glacial acetic acid through heating and ultrasonic treatment. The results revealed that SeNPs fused with CTS via intermolecular forces, thereby enhancing the tensile strength of the CTS film. The water contact angle of the CTS film increased with an increase in SeNPs concentration. The thermal stability and water retention ...
