This invention aligns and adheres conductive particulates 4 together to form a composite material. The process uses the combination of dielectrophoresis for alignment, and plasma dissociation followed by recombination for the adhesion. Particulates 4, e.g. carbon nanotubes, are dispersed in a dielectric fluid between two electrodes 1 & 2 which generate a non-uniform electric field. Dielectrophoresis causes the particulates to align and bridge the gap between the electrodes. When an arc breakdown occurs either between the two electrodes or between the particulates acting as extensions of the electrodes, the particulates adhere together to form a composite material, which may grow larger as the process continues. The process may be automated to control the electrode separation, signal power and frequency. |
