PPS 的结晶形态与其树脂的处理、结晶条件及成型条件有关。在 PPS/PTFE 共混物中,PTFE 的织态结构及其热力学性质与其是否预烧结有关。表面张力及结晶动力学测定结果表明,PPS 与 PTFE 的界面存在一定的相互作用。在界面上两者相互向对方表面转移,使对方表面能发生变化。PPS 的存在对 PTFE 结晶有一定的成核作用,而 PTFE 的存在对 PPS 的结晶并无促进作用。 The crystalline morphology of PPS is related to its resin processing, crystallization conditions and molding conditions. In PPS / PTFE blends, the weave structure and the thermodynamic properties of PTFE are related to whether it is pre-sintered or not. The results of surface tension and crystallization kinetics show that the interface between PPS and PTFE has some interaction. In the interface between the two mutually transfer each other’s surface, so that the other surface can change. The existence of PPS has a certain nucleation effect on the crystallization of PTFE, while the presence of PTFE does not promote the crystallization of PPS.
