摘要: 利用韶声波分散法将纳米_氧化认(TiO2)均匀分散到聚乙烯醇(PVA)水溶液中,通过原位法制备了一系列
不同TiO2含量的聚乙烯醇缩丁醛(PVB)纳米TiO2复合材料。采用FT-IR, UV-VIS, DSC和TG,AFM等平段对所
制得的原位复合材料的结构、微观形貌和性能讲行了研究。结果表明,在合成PVB讨程中引入纳米Ti( )>粒子,能更均匀地分散在PVB笨质中,PVB对TiU粒子具有很奸的位理效果,形成了以纳米TiO2粒子为核心的网络结构。该原位复合材料的力学性能尤其是韧性得到了明显捍高,在TiO2相对PVB含量较低时其断裂伸长率就达到纯PVB的6倍左右,同时该复合材料具有良奸的紫外屏蔽性能及耐热性能,而且材料溶解后的诱明度良奸。

Abstract: Through dispersion of nano-Ti()z in an aqueous PVA solution with supersonic vibration,PVB/nano-TiO2 composites were prepared. The microstructure,morphology,and properties of the composites were studied using FT-IR, UV-VIS, DSC, TG, and AFM. The nano-TiO2 was well dispersed in PVB. The mechanical properties were improved obviously by nano-TiO2,the elongation at break was increased by 6 times based on neat resin.Mcanwhilc,the composites showed excellent shielding to the ultraviolet ray. The heat-resistance of the composites was also improved.
