Synthesis and characterization of HDPE/N-MWNT nanocomposite films

Abstract

In this work, a series of nitrogen-doped multi-walled carbon nanotubes (N-MWCNTs) with several weight percentages (0.1, 0.4, 0.8, and 1.0 wt.%) were synthesized by catalytic chemical vapor deposition (CCVD) technique. The N-MWCNTs were first characterized and then dispersed in high-density polyethylene (HDPE) polymer matrix to form a nanocomposite. The HDPE/N-MWCNT nanocomposite films were prepared by melt mixing and hot pressing; a good dispersion in the matrix and a good N-MWCNT-polymer interfacial adhesion have been verified by scanning electron microscopy (SEM). Raman spectroscopy measurements have been performed on prepared samples to confirm the presence and nature of N-MWNTs in HDPE matrix. The X-ray diffraction (XRD) analysis demonstrated that the crystalline structure of HDPE matrix was not affected by the incorporation of the N-MWNTs.

Dependence of Z Parameter for Tensile Strength of Multi-Layered Interphase in Polymer Nanocomposites to Material and Interphase Properties

“…The different types of nanofillers have been used to strengthen and toughen the polymers. The most interesting aspect related to nanofiller is that they can improve the properties of polymers at very low filler concentrations compared to micro-particles and fibers [7–9]. This phenomenon can be described as nanoeffect which is the interactions at the atomic scale.…”

Photoluminescence and electronic interaction of multi-walled carbon nanotubes conjugated with oxadiazole materials

“…The proton resonances of anchored APND in MWCNTs-APND were broader and weaker than those of the APND. The signal from protons of MWCNTs-APND is not split and shifted up-field, which is likely attributed to the interaction between MWCNTs and APND, as well as magnetic-field induced partial orientation of MWCNTs [20,21], indicating that APND is attached on the surfaces of MWCNTs via amide linkages.…”

Comparative study of dielectric and mechanical properties of HDPE-MWCNT-SiO 2 nanocomposites

“…Chrissafis et al [4] have observed that addition of SiO 2 nanoparticles enhances the mechanical and thermal properties. It is also reported that the addition of modified MWCNT to HDPE results in the formation of nanocomposite films without loss of crystallinity [5]. Jiang et al [6] have studied the electrical conductivity and mechanical properties of HDPE reinforced with coated graphene platelets and MWCNT.…”
