Title: METHOD FOR PREPARING CARBON NANOTUBE CONDUCTIVE MICROSPHERES AND CONDUCTIVE ADHESIVE
Abstract:
Disclosed are a method for preparing carbon nanotube conductive microspheres and a conductive adhesive. Compared with an existing two-step method involving first preparing a plastic or resin microspheres, and then plating same with a conductive metal, the method for preparing carbon nanotube conductive microspheres does not require the separate preparation of a plastic or resin microspheres and a conductive layer, but relates to doping polymer microspheres with carbon nanotubes while enabling the cross-linking of a styrene monomer, a cross-linking agent and an initiator to form the polymer microspheres, in a spray granulation manner. In only one step, the carbon nanotube conductive microspheres with carbon nanotubes as a conductive medium are prepared, so that the process can be simplified, the working procedures can be reduced, and the cost can be saved; doping carbon nanotubes into the polymer microspheres can alleviate the influence of the thermal mismatch between the carbon nanotubes and a resin, thus ensuring the conductive properties of the conductive microspheres; furthermore, the entire preparation process does not involve any heavy metal salts, so that the biological toxicity can be reduced, and the environment is not polluted.
