Woodceramics, which are made of wood or wood-based materials impregnated by thermosetting resins and then carbonized at a high temperature, are porous carbon materials, the properties of which vary according to manufacturing conditions.
It has been reported that capacitors constructed with porous carbons demonstrate high specific capacitance as well as high power density, wherein the charge is stored at the electrode/electrolyte interface through reversible ion adsorption at high-surface-area porous carbon electrodes [13].
Among specific topics are the structure and texture of highly porous carbon nanospheres, a synthesis method for obtaining anode-supported tubular solid oxide fuel cells by slip casting, the microstructure and thermal characterization of copper based composites for thermal management in electronic packaging, cantilever structures based on piezoelectric materials for harvesting energy from low-frequency vibration, and anisotropic emission in strain-balanced quantum well solar cells.
Meng, Liu, and Fan have formed a conducting composite by compounding a conducting polymer with a porous carbon nanotube film by in-situ chemical polymerization.
Woodceramics are a new porous carbon material obtained from carbonized wood-based materials impregnated with phenolic resin in a vacuum furnace.
The heat turns the plastic into a fabric of pure, porous carbon strands.
[5] reported that a cobalt oxide-modified porous carbon was synthesized via a solvothermal method followed by a simple thermal treatment process and its high electrochemical performances (enhanced reversible capacity, excellent cyclic stability, high Coulomb efficiency, and good rate capability) were attributed to the interconnection networks of electrically conductive porous carbon and cobalt oxide nanoparticles, which could provide accessible route for electrolyte diffusion as well as intercalation of Li ions into the active sites, efficiently prevent volume expansion/ contraction of cobalt oxide during discharge/charge process, and decrease its inner resistance.
Using both a silica hard template and triblock copolymer soft templates, a phenolic resin was introduced and pyrolyzed to form the porous carbon monolith [9].
Wood is used as a precursor material which is carbonized under controlled temperature and atmosphere conditions to produce a porous carbon product having substantially the same cellular structure as the precursor wood.
