IX. Nanotube-Based Composites

Polymer membranes have been widely used in various applications, such as fuel cells, gas separation, biology, electrochemical sensors, electronics etc. Conducting polymer membranes are promising materials for construction in many areas. The anisotropy of electrical conductivity in such membranes may be interesting and can be achieved by filling polymers with structured carbonaceous compounds.
In this study we investigated composites made of thin transparent polymer membranes, in which regularly patterned vertically aligned carbon nanofibers (VACNF) or arrays of carbon nanotubes were incorporated across the film. Using electron beam lithography or nanoimprinting, patterned catalyst nanoparticles are prepared for the growth of the carbon nanostructures. The polymer matrix is added by a spin-coating method that the nanostructures can withstand. The membranes can be removed from the substrate with wet etching. The electrical properties of the composite membranes along and across the membrane were investigated.
