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 Fibers

In this study, electrical conductive yarns were prepared by wet-spinning technique and a physically coating process. Carbon black (CB) was used to make the fiber gaining electrical conductivity. The electrical conductivity and morphological characteristics of the developed conductive fibres were studied and compared. The results show that linear resistivity of the produced conductive yarns ranges from 1 to a few hundred kΩ per centimeter, mainly depending on processing technique and substrate fibers. It is also shown that the physically coating processes will not significantly affect the mechanical properties of the fibers and yarns. These conductive yarns are lightweight, durable, flexible, and cost competitive; and able to be crimped and subjected to textile processing without any difficulty.

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.

In this paper conductive yarns were made by coating the yarns with a solution having carbon black nanoparticles (CB) with an average diameter of 18 nm, polyvinyl alcohol (PVA) and water. For a continuous coating deposition it is necessary to obtain a solution of a certain consistency; for this reason, carbon black nanoparticles are mixed with the ingredients so that the resulting film deposited as a thin layer on the yarn to be conductive, and at the same time flexible. The carbon black nanoparticles tend to form aggregates; this is why the solution should be stirred continuously. The yarns used as support are different from the nature, fineness and structure point of view. Several variants of yarns were chosen in order to decide which ones are appropriate for obtaining conductive yarns that keep their specific initial properties. The variants of conductive yarns obtained were tested in terms of physical and mechanical properties (tensile strength, elongation), and from the viewpoint of electrical properties, electrical resistivity was measured. After coating the conductive layer, yarns shows greater rigidity, but can be used to obtain textile materials such as woven fabrics. After performing the measurements, it can be concluded that the yarns coated with a conductive solution based on CB shows electrical conductivity and can be used for obtaining conductive textile fabrics.

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.
