This study used fused deposition modelling to develop high-density polyethylene (HDPE) and its composites reinforced with carbon nanotubes (CNTs). The effect of varying the CNT content from 0.5% to 2% on microstructure and thermal behaviour was investigated. The thermal behaviour of developed HDPE composites was studied using thermogravimetric analysis and differential scanning calorimetry, while the phase analysis and chemical functionality were studied using X-ray diffraction and Fourier transform infrared spectroscopy. The XRD results showed that CNTs had no effect on the intensity or position of the peak for HDPE, whereas the FTIR results showed a decrease in the intensity of HDPE bands after the addition of CNTs due to physical interaction between them. The thermogravimetric analysis revealed no discernible change in the temperature of maximum weight loss following CNT addition. The DSC thermograms of HDPE composites revealed a small increase of up to 7% and 3% in glass transition and melting temperatures, respectively. The thermal conductivity as a function of CNT content was investigated, and it was discovered that as CNT content increased, the conductivity increased to an extent of 16% for 2% CNT content. |
