摘要 利用超声和三辊研磨机进行共混处理,然后浇注制备了含有不同质量分数纳米二氧化铈的不饱和聚酯树脂复合材料。用场发射扫描电镜(FE-SEM)和X射线能谱仪(EDS)对纳米CeO2在基体中的分散性进行表征,结果表明,共混处理时间对于分散性有显著影响。力学性能测试表明,纳米CeO2的引入可显著提高材料的拉伸强度和冲击强度;在研究的纳米粒子含量范围内,纳米CeO2含量在2%时,拉伸强度和冲击强度分别提高了69.5%和87.8%,在质量分数超过2%后,随着纳米粒子含量的增加力学性能开始降低。 CeO2 nanoparticles were dispersed in the unsaturated polyester resin(UPR) solution using ultrasonication and three-roll muller,and the CeO2/UPR composites specimens comprising different CeO2 content were prepared by casting technology.The dispersion behavior of CeO2 nanoparticles in the UPR matrix was characterized by field-emission scanning electron microscopy(FE-SEM) and energy dispersive X-ray spectrometer(EDS).The results showed that the dispersion was markedly impacted by mixed time.The mechanical properties tests indicated that the tensile strength and impact strength of the composites were reinforced with the addition of CeO2 nanoparticles.The tensile strength and impact strength reach a maximum respectively at 2% mass fraction,which is 69.5% and 87.8% higher than that of the pure UPR.The mechanical property turned to a decreasing tendency with the further supplement of the nanoparticles content(more than 2%).
