Preparation of a HDPE/Carbon Nanotube Composite

Abstract

This experiment adopted mixed acid (H 2 SO 4 :HNO 3 ¼ 3:1) to purify multi-walled carbon nanotubes, and used a silane coupling agent n-octyltriethoxysilane (OTES) to modify carbon nanotubes, respectively. Then we mixed OTES-modified carbon nanotubes (CNTs) with high-density polyethylene (HDPE) resin to make a composite. TGA analysis results revealed that as the CNTs'content increased, the Td 10 tended to rise. The amount of composite residual at 500 C also increased, as well as the composite electrical conductivity. When a concentration of 5% OTES was used to modify the CNT, the resultant composite exhibited better electrical conductivity.

Effects of (conductive polypyrrole)‐modified tire dust on the mechanical, electrical, and morphology properties of (low‐density polyethylene)/(tire dust) composites

“…However, LDPE/TD T composites showed lower capacitance than LDPE/TD composites because the presence of PPy lowered their charge‐discharge tendency. A similar observation has been reported by Yu et al ; the addition of carbon nanotubes to low‐density polyethylene significantly reduced the capacitance of the resultant composites, owing to the excellent electrical conductivity of such composites. In addition, a good dispersion of TD T in the LDPE phases was observed by SEM, which resulted in a better conducting network.…”

Properties of (Low‐density polyethylene)/(natural rubber)/(water hyacinth fiber) composites: The effect of polyaniline

“…The modified WHF PANI in the LDPE/NR/WHF PANI composites acted as a charge carrier; therefore, the composites tended to have higher conductivity than the LDPE/NR/WHF composites. A similar observation was reported by Yu et al . The addition of carbon nanotubes to high‐density polyethylene significantly reduced the capacitance of the composites owing to the excellent electrical conductivity of the (high‐density polyethylene)/(carbon nanotube) composites.…”

The Friction and Wear Properties of Short Carbon/CNT/PA6 Hybrid Composites Under Dry Sliding Conditions

“…Most industrial areas require the reinforced polyamide composites. Generally, the used reinforcing fillers involve glass fibers [3], wollastonite [4], magnesium salt (M-HOS) whisker [5], carbon fiber (CF), PET fiber, carbon nanotubes (CNT) [6], and Kevlar fiber [7]. Industrially, CF is the filler that is mostly utilized in reinforcing polyamide materials (PA6 and PA66) due to its high strength, good availability, and simple filling process.…”
