| 摘 要： | 对纳米二氧化钛粒子改性聚甲基丙烯酸甲酯(PMMA)透光复合材料的性能进行研究.通过将二氧化钛纳米粒子分别加在同轴共纺复合纳米纤维的壳/芯结构中,分析了相同含量二氧化钛粒子在不同结构中的分布状况以及对纳米纤维增强透光复合材料透光性和紫外光吸收性的影响.研究结果表明:分布在芯层中的纳米二氧化钛粒子对纳米纤维增强透光复合材料的透光性能影响较小,且能在200～400nm-1的紫外光区域产生明显的吸收峰.

| Abstract: | Development of nanofiber reinforced transparent composites added with nano-titanium dioxide(TiO2) particles was made in this paper,in which poly(methyl methacrylate)(PMMA) acted as the matrix material.Applying the same amount of TiO2 particles either in core or in shell part of co-axially electrospun composite nanofibers,their distribution status in different parts and their influence on optical properties of the transparent composites such as visible light transparency and ultraviolet light absorbency was ... |
