摘　　要：采用γ-(2,3-环氧丙氧)丙基三甲氧基硅烷(KH-560)对针状纤维素(CP)、片状滑石粉(Talc)和类球形二氧化硅(SiO_(2))进行改性,然后分别与可降解聚合物聚对苯二甲酸共己二酸丁二醇酯(PBAT)进行共混,研究了填料形貌对PBAT复合材料模量和抗蠕变性能的影响。结果表明:3种填料的加入均大幅提升了PBAT的拉伸模量和弯曲模量,其中,CP对PBAT复合材料的提升幅度最大,Talc次之,SiO_(2)最小。CP对PBAT的抗蠕变性能的提升幅度最大,Talc次之,SiO_(2)最差。The needle shaped cellulose(CP),flake like talc powder(Talc)and spherical silica(SiO_(2))were modified usingγ-(2,3-epoxypropanoxy)propyltrimethoxysilane(KH-560)and then blended with degradable polymer poly(butylene adipate-co-terephthalate)(PBAT)to investigate the effect of filler morphology on the modulus and creep resistance of PBAT composite materials.The results show that the addition of three types of fillers significantly increases the tensile modulus and bending modulus of PBAT.CP has the largest reinforcement amplitude on PBAT composite materials,followed by Talc,and SiO_(2) has the smallest.CP has the greatest improvement in the creep resistance of PBAT,followed by Talc,and SiO_(2) has the worst effect.
