| Abstract: | Solution blending used chemical cross-linking and physical cross-linking(Heat)to prepare chitosanpolyethylene glycol-negative oxygen ion(CS-PEG-NOI)composites,in which chemical cross-linking used glycerol(Gly),glutaraldehyde(Glu),graphene oxide(GO).The results show that cross-linking can effectively improve the performance of the composite coating agent.Physical cross-linking has a lower degree of cross-linking than chemical cross-linking and has a lower effect on its performance.Glycerol cross-linking can improve the dispersibility and hydrophilicity,however the stability decreased significantly.After cross-linking glutaraldehyde,its stability is improved,and its dispersibility and hydrophilicity are reduced.The graphene oxide can greatly improve the dispersion and stability,but the hydrophilicity is greatly reduced.The physical mechanical performance is increased and the moisture permeability of leather is decreased.Physical cross-linking can slightly improve the dispersion and the hydrophilicity becomes slightly lower. |
