摘要: 以环糊精修饰的二氧化钛纳米粒子作为光屏蔽剂,利用环糊精与金刚烷的包合作用作为自修复作用力制备了一种具有自愈合性能的光屏蔽涂料,并研究了其光屏蔽性能和自愈合性能.研究结果表明,该涂料能够与电缆护套软质基材牢固结合,具有较好的疏水性和较低的吸湿率(在相对湿度75%的环境中放置48 h后水接触角>90°;在相对湿度54%的环境中吸湿率<2%);该材料对紫外光具有较好的光屏蔽性能(紫外光屏蔽率>90%),并表现出良好的自愈合性能,在遭受损伤时,裂痕能反复多次恢复,拉伸性能可恢复80%以上.

Abstract: Self-healing light-shielding paints can not only reduce the photo-aging on the cable cover by ultro-violet, but also recover the micro-damage and hallrcuts on the surface of cable cover, improve the life of cable. In this paper, using nano particle of TiO2 decorated by β-cyclodextrin(β-CD) as light-shielding agents, we developed a new light-shielding paint, the self-healing function of which was realized by inclusion interaction between β-CD and adamantane. This paint can stick on the PVC sample tightly and demonstrate a good hydrophobicity and low hydroscopicity. It has an excellent light-shielding ability on ultraviolet(>90%). Moreover, this paints had a good self-healing ability, the crack made by knife can recover at least three times and its tensile property can recover beyond 80%.
