Effect of Laser Radiation on Carbon Nano-Tube Composite.

      Аннотация: Polymer composites are intensively studied for the new properties which are given by the combination of the properties of both polymer matrix and the filler respectively. When the concentration of the filler in the composite reaches the percolation value, the continuous bulk network structure is formed. If electrical conductive filler (Carbon black (CB)) is used, the composite properties can change from insulator to conductive ones. Electrical conductivity can change in the magnitude of several orders. Radar absorbing materials (RAMs) are the various processed materials whose function is to attenuate the electromagnetic radiation in the microwave band and may be obtained as: paints, composites, sheets, thin films, etc. Such materials are obtained from the addition of determined absorbing filler into different types of polymeric material. The combination of polymers with carbon nanotubes allows linking the properties of both materials to form new functional materials, with application in the microwave area.
