Development of microreactors made of vertically aligned carbon nanotube films

Microreactors consisting of multiwalled carbon nanotube (CNT) microchannels have been developed. Vertically aligned CNT films with negative pattern shapes of microchannels are grown on silicon oxide films, providing CNT microchannels. Polymethyl methacrylate plates are placed on the CNT microchannels for the flow experiments. Since CNTs are hydrophobic and the silicon oxide film is hydrophilic, fluids can flow in the silicon oxide regions in the CNT microreactors. Fermat’s spiral and Y-junction type multiwalled CNT microreactors were synthesized.
