【摘要】 试验采用溶胶-凝胶法制备纳米TiO2 并将其进行表面改性,加入到PVC 树脂中制得PVC/纳米TiO2膜,并研究其相关性能。结果表明:在每100 份PVC 中加入3 份纳米TiO2时,能较大地提高膜的拉伸强度和撕裂强度,而且不会对断裂伸长率有太大的破坏,膜的综合性能有所提高。
【Abstract】 The Nano-TiO2 particle has been prepared by Sol-Gel method and then modified. The PVC/Nano-TiO2 film has been prepared by adding Nano-TiO2 into S-1000 PVC resin, and its properties have been studied too. The results showed that tension strength and tear strength of PVC/ Nano-TiO2 film have been enhanced and elongation at break has been reduced a little by adding 3 doses of Nano-TiO2 to 100 doses of PVC resin.
