Plastic Parts

In the near future, carbon nanotubes containing plastic parts are likely to enter the environment in large quantities and, due to their resistance to degradation, the environmental impact may be even more important than that of similarly shaped plastic products. Thus, there is an immediate need to examine and understand the effect of recycling on the properties of polymer/carbon nanotube composites in order to develop sustainable recycling technologies. In this paper, polypropylene filled with different levels of multi-walled carbon nanotubes (MWCNTs) manufactured by injection molding was closed-loop recycled in order to investigate the effect of recycling and reprocessing on its rheological, electrical and mechanical properties. Preliminary results show that the PP/MWCNT composites keep the flow performance after mechanical recycling. Moreover, the stress and strain at break increase after one reprocessing cycle (mechanical recycling coupled with injection molding) whereas no statistically significant changes in electrical conductivity, Young modulus and tensile strength of the PP/MWCNT composites filled with 1, 3 and 5 wt.% were observed.

Concentration Series

In the last ten years carbon nanotube composites are in the focus of the researchers. Different composition of carbon nanotubes and polymers were produced by IDMX mixer. In the experiments polypropylene, polycarbonate and ABS polymers were used as matrix materials. Nanotube master batches were used to prepare different compositions. Concentration series were manufactured by the dynamic mixer. The prepared materials were characterised by scanning electron microscopy. The carbon nanotubes can be seen on the fractured surfaces. We did not find any sign of agglomerates in the materials. During the investigation of isothermal and nonisothermal crystallization of polypropylene nanocomposites it was shown that the carbon nanotube has nucleating effect on polypropylene. Mechanical properties were determined. It was found that the mechanical properties of the nanocomposites decreased. The flammability of the composites is significantly smaller than the original polymers. Polypropylene nanotube composites above 4% nanotube content were not dripping. It is most probable due to some kind of network structure of the material. We assume that the carbon nanotube creates a physical network in the polymers.

The Impact

Abstract In this paper, the impact of recycling and remanufacturing on the behavior of low-density polyethylene/multi-walled carbon nanotube (LDPE/MWCNT) composites is investigated. LDPE/MWCNT composites with 0.1–5 wt.%, previously manufactured by injection molding, were mechanically recycled and remanufactured by injection molding and 3D filament extrusion, and the rheological, electrical, and mechanical properties were analyzed and compared with those of virgin composites under the same conditions. Experimental results demonstrate that the recycled LDPE/MWCNT composites have similar rheological, electrical, and mechanical properties to virgin composites, if not better. Therefore, the recycled LDPE/MWCNT composites have a great potential for being used in engineering applications, while reducing the environmental impact.
