摘要
Abstract
In this article,TiO2 was surface modified by macromolecular polybasic acid(BA)and lauric acid(LA)and then used to whiten the PA6/GF composites through extrusion molding.The effect of modified TiO2 on the crystalliza-tion behavior and interfacial and mechanical properties of the composites were investigated.The results indicated that there was no significant influence on the improvement of mechanical properties of PA6/GF composites at an LA-modi-fied TiO2 content of 3 wt.%.However,the composites with BA-modified TiO2 obtained tensile strength,flexural strength and notched impact strength of 109 MPa,155 MPa,and 12.3 kJ/m2,respectively,which were higher than those of the composites with pure TiO2 by 11.1%,10.7%,and 68.5%,respectively.All parameters reached 85%or more of the results for the composite systems with the same amount of ZnS.关键词
