Abstract

Abstract A new chitosan derivative (CS-CHO) was successfully synthesized based on chitosan (CS) and cyclohexene oxide (CHO). It proved that CHO was successfully grafted onto the amino group of CS by N-alkylation reaction through the characterization of FTIR, XRD and DSC-TGA. The mechanical properties (tensile strength, folding endurance, tearing strength), optical properties (whiteness, glossiness) of the CS-CHO coated paper sample were tested. The results showed that the mechanical properties of the paper treated with 10 % CS-CHO increased significantly without changing the appearance of the paper. The paper permanence (tensile strength, folding endurance, tearing strength and pH) of the treated paper samples tested by dry-heat aging test. The results showed that the permanence of the treated paper samples was significantly improved compared with the blank aged paper samples, which indicated that CS-CHO had the function of deacidification while reinforcing the paper samples, providing the possibility for deacidification and reinforcement in one-step method and playing a positive role in the paper preservation.
