聚醚砚(PES)的化学结构为:。可以看出,PES分子链中同时具有苯环的刚性、醚基的柔性及砜基与整个结构单元形成的大共扼体系,因此PES具有强度高、耐温(可在180℃以上使用)、耐燃、耐辐射、抗酸、抗氧化、抗溶剂、生物相容、物理机械性能和绝缘性能优良等特点,是一种综合性能优异
The chemical structure of Polyether Inkstone (PES) is:. It can be seen that the PES has both rigidity of the benzene ring, flexibility of the ether group and a large conjugated system formed by the sulfone group and the entire structural unit in the molecular chain of the PES. Therefore, the PES has the advantages of high strength and temperature resistance (can be used above 180 ° C) Flame resistance, radiation resistance, acid resistance, oxidation resistance, solvent resistance, biocompatibility, physical and mechanical properties and excellent insulation properties and so on, is a comprehensive excellent performance
