Abstract:In this study, chitosan (CS) and maleic anhydride (MA) were used as the main raw materials to prepare maleoyl chitosan (MAAC)via TEMPO oxidation. The dialysis paper was prepared with the MAAC as the additives. The effects of the mass ratio of CS and MA on the substitution degree and solubility of the MAAC were studied, and the effects of MAAC dosage on the physical properties, air permeability and antibacterial properties of dialysis paper were also investigated. The results showed that the substitution degree of MAAC was higher and the solubility was better when the mass ratio of CS, MA and TEMPO was 1∶1.0∶0.08, and the light transmittance of the solution was greater than 80% under neutral and alkaline conditions. The dry and wet tensile index and tear index of dialysis paper after adding 2.0% MAAC were increased by 10.0%, 96.8% and 20.3%, respectively. The air permeability of dialysis paper after adding 2.0% MAAC reached 8.98 μm/(Pa·s), with a good antibacterial property. |
