以二苯醚、对苯二甲酰氯、间苯二甲酰氯为原料，制备了聚芳醚酮（PAEK），并以云母为填料，制备了PAEK/云母复合材料。采用聚对苯二甲酰对苯二胺（PPTA）改善云母与聚对苯二甲酰对苯二胺（PAEK）的界面粘结性能。这些材料的机械性能和表面摩擦行为进行了检查作为云母含量的函数。随着云母含量的增加，材料的拉伸模量增加，极限伸长率下降，而拉伸强度在特定组成下出现最大值。用PPTA处理云母后，云母酸与PAEK之间的界面结合力得到改善，表现为机械强度的提高，但不影响聚合物的玻璃化转变行为。这些材料的摩擦系数和磨损率受云母用量的影响。(C)2001爱思唯尔科技有限公司版权所有。
A composite material of a poly(aryl ether ketone) (PAEK), which was prepared from diphenyl ether, terephthaloyl and isophthaloyl chloride, was developed using mica as a filler. Poly(p-phenylene terephthalamide) (PPTA) was employed for the purpose of improving the interfacial adhesion between mica and PAEK. Mechanical properties and surface frictional behavior of these materials were examined as a function of mica content used. With increasing content of mica in the materials, the tensile modulus increased and the ultimate elongation decreased while the tensile strength exhibited a maximum value at a particular composition. Treatment of mica by PPTA improved the interfacial adhesion between mica acid PAEK as shown by improved mechanical strength, but did not affect the glass transition behavior of the polymer. Coefficient of friction and wearing rate of these materials were affected by the amount of mica used. (C) 2001 Elsevier Science Ltd. All rights reserved.
