Polypropylene (PP)/glass fiber (GF) composites showing excellent antistatic performance were prepared by a simple melt process blending PP with GF and a small amount of organic salts (OSs). Two types of OSs, tribuyl(octyl)phosphonium bis(trifloromethanesulfonyl)imide (TBOP-TFSI) and lithium bis(trifloromethanesulfonyl)imide (Li-TFSI), with equivalent anions were used as antistatic agents for the composites. It was found that the GF and OSs exhibited significant synergistic effects on the antistatic performance as well as the mechanical properties of the composites. On the one hand, the incorporation of GF significantly enhanced the electric conductivity of the composites at a constant OS loading. On the other hand, the two types of OSs improved the interfacial adhesion between the GF and the PP matrix, which led to an enhancement of the mechanical properties. This study showed that OSs had specific interactions with GFs and were absorbed exclusively on the GF surface. The GF network in the PP matrix provided perfect orbits for the movement of ions, inducing the excellent antistatic performance exhibited by the PP/GF composites at an OS loading of as low as 0.25 wt % when the GF formed a network in the PP matrix.

玻璃纤维网络作为离子的轨道：具有极低有机盐含量的优异抗静电PP / GF复合材料的制造
通过将PP与GF和少量有机盐（OSs）混合的简单熔融工艺，即可制备出具有优异抗静电性能的聚丙烯（PP）/玻璃纤维（GF）复合材料。两种类型的OS，三（三氟甲磺酰基）酰亚胺三丁基（辛基）phosph（TBOP-TFSI）和双（三氟甲磺酰基）酰亚胺锂（Li-TFSI），具有相同的阴离子，被用作复合材料的抗静电剂。发现GF和OS对复合材料的抗静电性能和机械性能表现出显着的协同作用。一方面，在恒定的OS负荷下，GF的加入显着增强了复合材料的电导率。另一方面，两种类型的OS改善了GF和PP基体之间的界面附着力，从而提高了机械性能。这项研究表明，OS与GF具有特定的相互作用，并且仅在GF表面被吸收。PP基体中的GF网络为离子的运动提供了完美的轨道，当GF在PP基体中形成网络时，在OS负载低至0.25 wt％时，诱导了PP / GF复合材料表现出的优异的抗静电性能。
