Thin films of semiconducting and unsorted carbon nanotubes (CNT) are prepared on a transparent and flexible cyclic olefin polymeric substrate. The CNT biocompatibility is analyzed using L929 mouse fibroblasts and Human Umbilical Vein Endothelial Cells (HUVEC). Highly conductive poly (3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS) films are also tested on the same substrate as an alternative...
Fractal growth of polypyrrole results in the production of organic material matrix with improved surface area and electrical properties. The interaction of different surfactants and progressive polymerization of monomers of pyrrole during electrochemical process improve fractal growth mechanisms and contribute with development of material with superior response. In addition to high level of conductivity,...
Multilayer graphene (MLG)/polydimethylsiloxane (PDMS) composite has been prepared by infiltrating free-standing MLG paper, obtained through the vacuum filtration of MLG-suspension using a nanoporous filter, with PDMS prepolymer. Electrical properties of both free-standing MLG paper and MLG/PDMS composite paper were investigated by four-point probe measurements. The obtained results show that the annealed...
