PAEK简介；

PAEK聚芳醚酮是一类主链含有醚键和羰基的芳杂环聚合物，醚键和羰基通过亚苯基以不同序列相连，从而构成了各种类型的PAEK。分子链中存在的芳环、杂环，形成“螺形”、“片状”和“梯形”结构，因而化学键能高,链段刚性大，从而具有很高的玻璃化温度Tg、较高的热分解温度和较低的可燃性；其分子主链上的共轭双键,使分子的规整性好, 因而其力学性能优异;刚性较强的分子链间作用力(如氢键) 及结晶性等结构特点,使得分子链紧密堆砌, 溶剂分子不易渗入,因而又具有良好的耐溶剂性和耐化学药品性。同时大分子含有大量的醚键又赋予其韧性，醚键越多，其韧性越好。通过增大分子量还可以提高其韧性和耐疲劳性，并可将其熔融粘度调整到适合于注塑成型。
