中文摘要：
采用纳米TiO2对壳聚糖进行改性，制备了一种新型抗菌防霉剂，并将新型抗菌防霉剂喷涂于纸张表面，考察日常光照环境下其对纸张的防霉性能。实验结果表明，经新型抗菌防霉剂处理后的纸张具有很好的防霉特性，对黑曲霉菌的24h杀菌率均达到99.99%，且持续有效。此外，采用AATCC-100法研究了纸张表面霉菌生长情况，结果表明霉菌在抗菌防霉剂处理后的纸张表面不能存活。
英文摘要：
A novel antibacterial and anti-mildew agent （APt） was prepared using chitosan modified by nano- TiO2, and the anti-mildew behavior of paper treated with this material was studied under natural illumination. The paper treated with the novel antibacterial and anti-mildew agent showed excellent anti-mildew activity, with the bactericidal ratio of Aspergillus niger reaching 99.99 96 after 24 h. In addition, the livability of Aspergillus niger on the surface of paper treated with the AAA was studied by the AATCC-100 method, and it was found that Aspergillus niger could not survive on the surface of paper treated with the agent.
