Glass-Fiber Networks as an Orbit for Ions: Fabrication of Excellent Antistatic PP/GF Composites with Extremely Low Organic Salt Loadings

Abstract

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.

Ionic Liquids Incorporating Polyamide 6: Miscibility and Physical Properties

“…Our group has previously investigated the cooperation of RTIL to different polymer matrices. One of the authors [29] prepared polypropylene (PP)/glass fiber (GF) composites with excellent antistatic performance by blending with a small amount of ionic liquid, in which GF networks offered an orbit for ions to transfer. In another work, antistatic nanofibers based on poly (vinylidene fluoride) (PVDF) and a RTIL, 1-butyl-3-methylimidazolium hexafluorophosphate [BMIM][PF 6 ], were fabricated via electrospinning [30].…”

A Facile Modifier-free Approach to Fabricate Antistatic Superhydrophobic Composite Coatings with Remarkable Thermal Stability and Corrosion Resistance

“…Surface Resistivity (SR) can be applied to measure the antistatic properties of coatings [58] . Table S2 shows the surface resistivity and logarithmic values of the superhydrophobic coating with different carbon contents (g and wt%).…”

Self‐assembly and antistatic property of ionic liquid crystalline polymers

“…Ionic LC materials have been widely used in soft materials, 14,15 ion‐conducting materials, 16–19 and antimicrobial finishing materials 20 up to now. Furthermore, they will provide infinite possibilities for more applications in permanent antistatic agents similar to polymerized ionic liquid that are considered to be promising additives 21–24 . Inspired by previous strategies to prepared antistatic materials, we endeavor to utilize isophthaloyl chloride, bromo‐alkane‐dioyl dichloride, 4,4′‐biphenol, isosorbide, and 4,4′‐bipyridine as polymeric raw material with the aim of preparing ionic liquid crystalline polymers (ILCPs) containing quaternary ammonium salt groups with excellent ionic conductivity and competent antistatic performance.…”
