In order to develop environmentally friendly conductive polymer composites, polylactic acid (PLA) was melt blended with natural rubber (NR), with addition of carbon black (CB) as the conductive filler. It was found that the PLA/NR blends were immiscible, and the sea-island and co-continuous morphological structures were observed at PLA/NR with ratio of 80/20 vol% and 60/40 vol% respectively. Addition of CB to 60/40 PLA/NR matrix, brought the composites to become electrically conductive at CB content of 2 phr. It was also found that the impact strength of PLA/NR/CB composite is better than that of the neat PLA.

The main objective of this work is to develop conductive yarns to be used as electrical wiring in e-textiles with the typical mechanical properties of a textile yarn. Present work deals with the study of conductive polymer composites filaments of PP (polypropylene) with CB (carbon black), carbon black of high conductivity (CBHC) and CF (carbon fibers) .The novelty of this work resides in creating oriented filaments using traditional fiber processing techniques together with a specially designed drafting machine. In the authors’ opinion, the composite conductivity could be improved with the orientation of the (nano)carbon-based fillers by melt drawing after extrusion in order to facilitate the flow channels creation.

Conductive Polymer Composites

ABSTRACTIn an effort to determine the optimal balance of electrical and mechanical performance for electrically conductive polymer composites, three figures of merit were evaluated. All three figures of merit displayed peaks and/or discontinuities at a particular filler loading. These loadings appear to correspond to the critical pigment volume concentration for a given system. Composite systems based upon latex as the matrix starting material showed peaks in the figures of merit at very low carbon black concentrations (10 vol%), while composites prepared with polymer solutions or melts had peaks above 20 vol% carbon black. These differences in behavior are attributed to differences in microstructural evolution that occur with filler loading.

Electrical Percolation Threshold

The effect of annealing on the electrical and rheological properties of polymer (poly (methyl methacrylate) (PMMA) and polystyrene (PS)) composites filled with carbon black (CB) was investigated. For a composite with CB content near the electrical percolation threshold, the formation of conductive pathways during annealing has a significant impact on electrical conductivity, complex viscosity, storage modulus and loss modulus. For the annealed samples, a reduction in the electrical and rheological percolation threshold was observed. Moreover, a simple model is proposed to explain these behaviors. This finding emphasizes the differences in network formation with respect to electrical or rheological properties as both properties belong to different physical origins.
