High strength Polypropylene (PP)/glass fiber (GF) composites with excellent antistatic performance were prepared by binary incorporation of maleic anhydride grafted polypropylene (MAPP) and lithium bis(trifloromethanesulfonyl)imide (Li-TFSI) into PP/GF composites. Li-TFSI was used as antistatic agents and MAPP was added as the interfacial binder between GF and PP matrix. It was found that the interface between PP and GF can be tuned by the binary addition of MAPP and Li-TFSI. The mechanical properties of PP/GF composites are enhanced drastically with the addition of MAPP. However, Li-TFSI induces the decreasing of the mechanical properties with enhanced antistatic performance of the composites. The investigation showed that Li-TFSI, as a high polar agent, breaks the physisorbed silane on the glass fiber, which induces the deterioration in the strengthening effects of MAPP. At the same time, the Li-TFSI is absorbed on the surface of GF and the ions are ready to move along the GF, so the antistatic performance is achieved. The specific interactions between Li-TFSI, GF and MAPP make it possible to design the interface of PP/GF composites by the binary incorporation of MAPP and Li-TFSI. Therefore, high performance PP/GF composites with both excellent antistaticity and high strength can be achieved.

通过将马来酸酐接枝聚丙烯（MAPP）和双（三氟甲磺酰基）酰亚胺锂（Li-TFSI）二元掺入PP / GF复合材料中，制备了具有优异抗静电性能的高强度聚丙烯（PP）/玻璃纤维（GF）复合材料。使用Li-TFSI作为抗静电剂，并添加MAPP作为GF与PP基体之间的界面粘合剂。发现可以通过二进制添加MAPP和Li-TFSI来调节PP和GF之间的界面。添加MAPP可以大大提高PP / GF复合材料的机械性能。然而，Li-TFSI导致机械性能下降，同时增强了复合材料的抗静电性能。调查显示，Li-TFSI作为高极性试剂，会破坏玻璃纤维上的物理吸附硅烷，这会导致MAPP的强化效果下降。同时，Li-TFSI被GF吸收，离子准备沿GF移动，从而实现了抗静电性能。Li-TFSI，GF和MAPP之间的特定相互作用使得通过MAPP和Li-TFSI的二元结合来设计PP / GF复合材料的界面成为可能。因此，可以获得兼具优异的抗静电性和高强度的高性能PP / GF复合材料。
