Influence of Ionomer and Cyanuric Acid on Antistatic, Mechanical, Thermal, and Rheological Properties of Extruded Carbon Nanotube (CNT)/Polyoxymethylene (POM) Nanocomposites

Abstract

The electrical properties of carbon-based filler-embedded polymer nanocomposites are essential for various applications such as antistatic and electromagnetic interference (EMI) applications. In this study, the impact of additives (i.e., ethylene-co-acid-co-sodium acid copolymer-based ionomer and cyanuric acid) on the antistatic, mechanical, thermal, and rheological properties of extruded multiwalled carbon nanotube (MWCNT)/polyoxymethylene (POM) nanocomposites were systematically investigated. The effects of each additive and the combination of additives were examined. Despite a slight reduction in mechanical properties, the incorporation of ionomer (coating on CNTs) and/or cyanuric acid (π‐π interaction between CNTs and cyanuric acid) into the POM/CNT nanocomposites improved the CNT dispersity in the POM matrix, thereby enhancing electrical properties such as the electrical conductivity (and surface resistance) and electrical conductivity monodispersity. The optimum composition for the highest electrical properties was determined to be POM/1.5 wt% CNT/3.0 wt% ionomer/0.5 wt% cyanuric acid. The nanocomposites with tunable electrical properties are sought after, especially for antistatic and EMI applications such as electronic device-fixing jigs.

Hygroscopic Behavior of Polypropylene Nanocomposites Filled with Graphene Functionalized by Alkylated Chains

“…The mechanical properties of polymer nanocomposites generally depend on the particle size, degree of dispersion, interfacial characteristics, and additive content [ 7 ]. Incorporation of nanofiller has a significant effect on the melt flow and viscosity of composite and parts processing [ 8 ]. The surface treatment of nanofillers is being actively researched as uniform dispersion and interface characteristics are crucial to achieving superior physical properties compared to general polymer composites [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 ].…”

Enhancing the Electrical Conductivity and Strength of PET by Single-Wall Carbon Nanotube Film Coating

“…The square resistance of the SWCNT/PET films was measured with a four-point probe meter. The obtained sheet resistances together with the results for CNT-based polymer antistatic packaging materials in the literature ,,− are shown in Figure a and supplement Table S2. We further measured the surface square resistance distribution of a SWCNT/PET composite film in an area range of 40 × 40 mm 2 (Figure S10a), showing an averaged square resistance of ∼128 Ω/□ with a relative standard deviation of 4.2% (Figure S10b).…”

Synthesis and application properties ofpolyaniline‐amino‐carbonnanotube antistatic agents

“…However, surface‐active agent‐type antistatic agents' performance is susceptible to environmental humidity, and polymer‐type antistatic agents can achieve antistatic effects only when added in higher amounts 5,12,13 . Therefore, conductive filler‐based antistatic agents such as carbon black (CB), 14,15 carbon nanotubes (CNTs), 16–18 graphene, 19,20 and so on that are carbon‐based are better choices for preparing antistatic polymers. Yang et al prepared CB/Ag‐Ms/PP composites with a CB loading of 30 wt% and a surface resistance of 10 8 Ω 21 .…”
