| 英文摘要 | Novel biodegradable three-dimensional (3d) composites with good mechanical properties have been prepared by coagulation of a chitosan/polyvinyl pyrrolidone (cs/pvp) solution in naoh. for example, the strength and modulus of cs/pvp (1/1) were 82.5 mpa and 1.86 gpa, increasing 237% and 644% compared with cs, respectively. scanning electron microscopy and fourier transform infrared analysis suggest that the pvp component did not dissolve during the preparation process. the nonsolution of the composites is attributed to the extremely strong hydrogen bonding formed between the cs and pvp macromolecules. it was also found that there are synergistic effects between the formation of hydrogen bonding with pvp and cross-linking with glutaraldehyde (ga) for the improvement in the mechanical properties of cs. the mechanism of strength improvement has been discussed thoroughly from the aspects of free volume. |
