摘要

1)在壳聚糖(CS)中加入poss型磷氮阻燃剂(后简称NH2-POSS)和银纳米粒子(Ag NPs)，制备了一种新型木材表面阻燃抗菌复合膜涂层。研究了NH2-POSS含量(CS质量分数为0%、0.5%、1%、3%、5%和7%)对木材复合膜涂层结构和性能的影响。采用共混-传导法制备了复合薄膜。测定了复合膜的接触角、拉伸性能和抗菌效果，并用红外光谱技术对其进行了表征。结果表明，NH2-POSS的加入不仅可以提高膜的韧性，还可以提高膜的阻燃性，从而提高膜在木制品中的应用。然而，随着NH2-POSS的加入，复合膜的透明度被削弱。复合膜对大肠杆菌生长的抑制作用随着Ag NPs的增加而增强。本研究为功能性木材的应用奠定了基础。

Preparation of Flame Retardant and Antibacterial Wood with Composite Membrane Coating

1) A novel flame retardant and antibacterial composite membrane coating for wood surfaces was prepared by adding POSS-based phosphorous nitrogen flame retardant (later referred to as NH2-POSS) and silver nanoparticles (Ag NPs) to chitosan (CS). The effects of NH2-POSS content (mass fractions of CS 0%, 0.5%, 1%, 3%, 5%, and 7%) on the structure and properties of the composite membrane coating on wood were investigated. The composite film was prepared by the method of blending and ducting. Contact angle, tensile property and antibacterial effects of the composite film were measured, and infrared spectroscopy was used. The results show that the addition of NH2-POSS can not only improve the toughness of the membrane, but also the flame retardancy of the membrane, which improves the application of the membrane in wood products. However, with the addition of NH2-POSS, the transparency of the composite membrane was weakened. The inhibitory effect of the composite membrane on the growth of Escherichia coli was enhanced with the increase in Ag NPs. This research provides a foundation for the application of functional wood.

期刊介绍： The Journal of the Korean Wood Science and Technology (JKWST) launched in 1973 as an official publication of the Korean Society of Wood Science and Technology has been served as a core of knowledges on wood science and technology. The Journal acts as a medium for the exchange of research in the area of science and technology related to wood, and publishes results on the biology, chemistry, physics and technology of wood and wood-based products. Research results about applied sciences of wood-based materials are also welcome. The Journal is published bimonthly, and printing six issues per year. Supplemental or special issues are published occasionally. The abbreviated and official title of the journal is ''J. Korean Wood Sci. Technol.''. All submitted manuscripts written in Korean or English are peer-reviewed by more than two reviewers. The title, abstract, acknowledgement, references, and captions of figures and tables should be provided in English for all submitted manuscripts.
