摘　　要：采用原位聚合法,用经表面处理的纳米TiO_2对钼酚醛树脂进行填充改性,制备了钼酚醛树脂/TiO_2纳米复合材料,研究了纳米TiO_2用量对复合材料耐热性和力学性能的影响。结果表明,TiO_2用量为1％时,纳米复合材料的玻璃化温度和冲击强度达到最大值;TiO_2用量为3％时,纳米复合材料的拉伸弹性模量和拉伸强度达到最大值。The nano-composites of molybdenum-modifying phenolic resin filled with the treated nano-titanium dioxide were prepared by in-situ polymerization. The effect of Ti02 nano-particles on the heat resistance and mechanical properties of nano-composites were studied. The results show that the heat resistance and impact strength of the nano-composites are maximum when the content of Ti02 nano-particles is 1 % , the tensile modulus and tensile strength of the nano-composites are maximum when the content of Ti02 nano-particles is 3%.
