| abstract | PARTICULATE MATERIALS, COMPOSITES COMPRISING THEM, PREPARATION AND USES THEREOF The application discloses methods of processing particulate carbon material, such as graphitic particles or agglomerates of carbon nanoparticles such as CNTs. The starting material is agitated in a treatment vessel in the presence of low pressure (glow) plasma generated between electrodes, e.g. between a central electrode and an outer rotating conductive drum containing the material for treatment. Preferably the material is agitated in the presence of conductive contact bodies such as metal balls, or other contact formations with relatively high specific surface area, on the surface of which plasma glow is present and amongst which the material to be treated moves. The methods are found to effectively deagglomerate nanoparticles, and to exfoliate graphitic material to produce very thin (few-layer or monolayer) graphitic sheets showing graphene-type characteristics. The resulting deaggregated or exfoliated carbon nanomaterials are an aspect of the disclosure, as is their use dispersed in composite materials, e.g. conductive polymeric composites for electric or electronic articles and devices. The particle surfaces can be functionalised by choosing appropriate gas in which to form the plasma. The invention is advantageous in using safe, dry and moderate conditions to achieve a high degree of deaggregation or exfoliation compared with previous aggressive chemical methods such as 0 acid treatment. 6983369 1 (GHMatters) P94205.AU.1 SAMANTHA ------------------- 5 43 - -- - - -- gas - -32' 4. . . . . . . 4 8 -95 44 -\52 -8 -v FIG. 4 FIG. 5 |
