Preparation of high antistatic HDPE/polyaniline encapsulated graphene nanoplatelet composites by solution blending

Abstract

High antistatic HDPE composites were firstly prepared by solution blending with polyaniline encapsulated graphene nanoplatelets nanocomposites.

Preparation of antistatic high‐density polyethylene composites based on synergistic effect of graphene nanoplatelets and multi‐walled carbon nanotubes

“…Using a synergistic effect between 2 fillers can be an efficient way to tackle these problems, as reported in other systems, such as nanomagnetite and carbon nanofiber, CNTs and graphene, and carbon black and CNTs . A compatibilizer has usually been used to improve the compatibility between nanofillers and the polymer matrix, including maleic anhydride grafted HDPE, ethylene‐vinyl acetate (EVA) copolymer, and ethyl oleate . EVA is suitable as a compatibilizer because it is a kind of thermoplastic material that consists of vinyl monomer and vinyl acetate (VA) monomer.…”

Effectiveness of PANI/Cu/TiO2ternary nanocomposite on antibacterial and antistatic behaviors in polyurethane coatings

“…In other words, content of the ternary nanocomposite at the percolation threshold leads to the formation of an infinite three dimensional conductive network throughout the polymer matrix which thereby renders the coating samples a reliable antistatic behavior. Based on the definition of the industry standards of ANSI/EIA‐541‐1988 (USA), and ANSI/ESD S541‐200 (USA), electrostatic dissipative (ESD) material having the electrical surface resistivity at 10 5 –10 12 and 10 4 –10 11 Ω/sq, respectively . Also, the military handbook DOD‐HDBK‐263 defines charge dissipative as a material which has an electrical surface resistivity between 10 5 and 10 9 Ω/sq .…”

Recent progress on nanostructured conducting polymers and composites: synthesis, application and future aspects

“…The results also indicated that composite fiber with low PANI content had satisfactory values of decay time and good antistatic properties. Wang et al [395] reported high-density polyethylene (HDPE) nanocomposites with graphene nanoplatelets (GNP) coated PANI as filler synthesized by in situ polymerization. The surface resistivity and volume resistivity (ρ v ) decreased sharply with addition of 10 wt.% GNP@PANI.…”

“…The most used methods for improving the antistatic performance are to reduce the surface resistivity or increase conductivity of the surface and to reduce the generation of triboelectric charge. For antistatic materials, the surface resistivity (ρ s ) should remain between 10 9 and 10 14 Ω sq −1 defined by military handbook and 10 5 to 10 12 Ω sq −1 defined by industry standards [394,395]. Another method to determine antistatic materials is to record the antistatic charge decay time, where a voltage is applied on the surface of the material (usually 5 kV) and the time required to decay to 10% of its initial strength is recorded.…”
