An extrusion melt fiber spinner is proposed for the fabrication of Multiwall Carbon Nanotube (MWNT) Polylactide (PLA) fiber composites. The melt fiber drawing system includes only feed rollers and a draw roller to allow the investigation of as-spun properties of the PLA fibers without the conventional heat treatment. The influence of the drawing parameters on the fiber quality is characterized by measuring the fiber diameters and draw ratios. Preliminary studies demonstrate that orientation and dispersion of MWNTs is feasible with this melt spinner design with improvements on the mechanical and thermal properties. Differential scanning calorimetry (DSC) results show an increase in the rate of cold-crystallization with increasing MWNT loading and tensile tests show that there is an optimal Young’s modulus for 0.5 wt% MWNT loading.

In this paper, multiwall carbon nanotube-ZnO (MWCNT/ZnO) was melt-blended with polyethylene (PE) by a Haake-Buchler Rheomixer. The mechanical properties, thermal stability and dispersion degree of the composite materials was characterized. Differential scanning calorimetry, X-ray diffraction analysis, thermogravimetry, tensile test and SEM were carried out. The results showed that with the addition of MWCNT/ZnO, the crystallinity and thermal degradation temperature of PE changed. 0.2phr MWCNT/ZnO/PE exhibited crystallinity that was 10% higher than PE. With the addition of MWCNT/ZnO, the tensile strength of PE decreased gradually, but the elongation at break increased first and then decreased. When MWCNT/ZnO content is 0.2phr, the elongation at break of the composite is close to 532.21%, which is 116% higher than that of pure PE.
