Preferential Alignment

Conductive polymer nanocomposites (CPNCs) have gained a lot of attention by the researchers, in recent times, due to their diverse technological applications in different domains. This paper discusses the additive manufacturing of conductive polymer nanocomposite. Maghemite-Multiwalled carbon nanotubes were synthesized, and later dispersed in an acrylate resin, followed by curing with UV DLP 3D printer, under the presence of external magnetic field. Maghemite-Multiwalled carbon nanotubes showed superior magnetic properties, when compared to Multiwalled carbon nanotubes and lead to improvements in preferential alignment of filler material in the polymer matrix. The initial experimental results show preferential alignment of Maghemite-Multiwalled carbon nanotubes in the polymer matrix under the influence of external uniform magnetic field, at an intensity of 120 Gauss.

The piezoresistivity, expressed as the relative resistance variation with imposed strain for conductive polymer nanocomposites, was analyzed by employing two models, developed elsewhere, and a new one proposed in the present work. The corresponding experimental results of three different types of polymer nanocomposites, namely styrene-butadiene rubber reinforced with carbon black and multi walled carbon nanotubes, poly-vinylidene-fluoride and polypropylene reinforced with multi-walled carbon nanotubes, were comparatively studied, on the basis of the employed models. An effort was made to explore the working mechanisms which control the relative resistance change with strain. The effect of polymer type, the strain range and the nano-filler type and weight fraction were investigated.

Efforts in the field of polymeric nanocomposites reinforced by carbon nanotubes are presented in the literature from many years. The discussed problems are connected with the characterization of nanocomposites and the modeling of elastic and fracture behavior at the nanoscale. The experimental investigations and the theoretical modeling are conducted simultaneously. The theoretical approaches try to elucidate the experimental observations. In the present paper a brief overview of the analytical and numerical modeling of polymeric nanocomposites reinforced with carbon nanotubes is presented. The attention is mainly focused on the molecular dynamic models, the continuum mechanics approaches and finally the multi-scale models are discussed. The good and wrong sides of the models are pinpointed. Also a comparison between values of Young's modulus of carbon nanotube/polymer nanocomposites for various methods is presented.
