摘要

摘要: 采用水热合成法制备拟薄水铝石(AlOOH)纳米棒，以3-氨基丙基三乙氧基硅烷(APTES)为表面改性剂，制得mAlOOH，以环氧树脂(Epoxy，EP)为基体，制备AlOOH/EP和mAlOOH/EP复合材料。研究AlOOH和mAlOOH的填充量对AlOOH/EP及mAlOOH/EP复合材料性能的影响。结果表明，mAlOOH明显提高了mAlOOH/EP复合材料的力学性能。mAlOOH的填充量为4wt%时，mAlOOH/EP复合材料的冲击强度和弯曲强度分别比聚合物基体分别提高了259%和44%；填充量不超过5wt%时，mAlOOH/EP的介电常数与介电损耗均略低于纯环氧树脂。当添加量为3wt%时，mAlOOH/EP具有最低的介电常数和介电损耗及最高的玻璃化转变温度(123℃)。

Abstract: Boehmite (AlOOH) nanorods were prepared by hydrothermal method and modified by 3-aminopropyltriethoxysilane (APTES) to obtain modified boehmite (mAlOOH). Then, AlOOH/epoxy (EP) and mAlOOH/EP composites were fabricated by using the EP as the matrix. The effects of the contents of AlOOH and mAlOOH on the properties of the AlOOH/EP and mAlOOH/EP composites were systematically studied. The results show that the mechanics properties of mAlOOH/EP composites are obviously improved by mAlOOH. The impact strength and flexural strength of 4wt% mAlOOH/EP composites are increased by 259% and 44% than that of neat EP, respectively. Both dielectric constant and dielectric loss of mAlOOH/EP composites are slightly lower than those of the pure EP with mAlOOH no more than 5wt%. The mAlOOH/EP composites with 3wt% mAlOOH exhibit excellent global properties with the lowest dielectric constant and the lowest dielectric loss, as well as the highest glass transition temperature (123℃).
