Here I will describe a simple and ultrafast method to form C-N or C-O, in various carbon nanomaterials including activated carbon, carbon nanotubes, and graphene, by ultrasonic chemical reaction and then fabricate it binder-free energy storage system. In addition, this ultrasonic chemistry can expand into synthesis of conjugated microporous polymer materials to overcome processing challenges related to these materials and then apply it supercapacitors in-situ. Ultrasonic chemistry simultaneously achieves oxidative C–C coupling polymerization and fabrication of thin films. The reaction yield, porosity, and capacitance of the prepared CMP films were strongly dependent on the applied ultrasonic frequency (120 and 180 kHz). Furthermore, USC was used to prepare highly conductive, 3D porous electrodes by a layer-by-layer sequential deposition of CMPs and single-walled carbon nanotubes. |
