以自制改性纳米TiO2为填料,聚氨酯(PU)作为基体,充分反应后,通过红外光谱和扫描电镜图分析,证实制得改性纳米TiO2/PU复合材料。测试结果表明,当纳米TiO2含量分别为3%、6%和2%时,复合材料的冲击强度、拉伸强度和体积电阻率达到最大值,分别为16.63kJ/m2、45.68MPa和4.8×1016Ω·cm。
The modified nano-TiO2/polyurethane(PU) composite was prepared by taking the modified nano-TiO2 as the filler and PU as the matrix.After full reaction,it was confirmed by infrared spectrum and SEM analysis.The results shown that when the content of nano-TiO2 was 3%,6% and 2%,the impact strength,tensile strength and volume resistivity of the composite reached the maximum,which were 16.63kJ/m2,45.68mPa and 4.8×1016Ω·cm,respectively.
