| 中文摘要: |
| 目的 研究羧甲基壳聚糖纳米颗粒的制备以及抗菌纸的力学性能。方法 以CaCl2为离子交联剂，通过离子交换反应， 将羧甲基壳聚糖制成纳米颗粒， 然后将纳米羧甲基壳聚糖水溶液涂布在纸张表面，制备成抗菌纸并检测其力学性能。结果 随着羧甲基壳聚糖溶液浓度的升高， 所需的交联剂钙离子浓度也有所升高， 抗菌纸的环压强度、 耐破度及撕裂度随着涂布纳米羧甲基壳聚糖浓度的增加均有所增加，厚度没有明显变化， 能满足包装需求。结论 经过纳米羧甲基壳聚糖的涂布， 抗菌纸的机械强度均有所增加， 能满足抗菌纸的力学性能要求。 |
| 英文摘要: |
| The aim of this work was to study the preparation of carboxymethyl-chitosan nanoparticles and the mechanical performance of antibacterial paper. Carboxymethyl-chitosan nanoparticles were prepared using CaCl2 as ion crosslinking agent with ion-exchanging method, then antibacterial paper was prepared by coating the paper surface with nano-carboxymethyl-chitosan solution and its mechanical performance was studied. With increasing concentration of carboxymethyl-chitosan solution, the required concentration of the crosslinking agent calcium ion was also increased. The mechanical performance of antibacterial paper such as ring crush strength, bursting strength and tearing strength increased with the increasing nano-carboxymethyl-chitosan concentration coated, while the thickness showed no obvious difference, meeting the packaging requirement.By the coating of nano-carboxymethyl chitosan,some mechanical performance of antibacterial paper is better than the control paper， and it can meet the requirements of the mechanical properties of the antibacterial paper. |
