摘要
制备了四针状氧化锌晶须(T-ZnOw)/聚丙烯复合材料,研究了不同偶联剂处理的T-ZnOw及其用量对复合材料力学性能的影响,并对偶联机理做了初步探讨。研究结果表明,当添加T-ZnOw质量分数为20%时,复合材料的力学性能最好;与处理前相比,处理后的T-ZnOw复合材料的拉伸强度和冲击强度有不同程度的提高;不同偶联剂处理的T-ZnOw对复合材料力学性能的影响不同。
A series of tetrapod zinc oxide whisker/polypropylene (T-ZnOw/PP) composites were prepared. The effects of T-ZnOw modified by different coupling agents and its dosage on properties of T-ZnOw/PP composites were studied. The interaction mechanism between the coupling agents and the PP matrix was also explored briefly. The results show that when mass fraction of T-ZnOw is 20%, the mechanical properties of the composites reach their optimum values. The tensile strength and impact strength of the composites after treatment by coupling agent are improved to a given extent compared with those before treatment. T-ZnOw modified by different coupling agents exerts different influences on the mechanical properties of the composite materials.
