FABRICATION METHOD OF HIGHLY CONDUCTIVE SILICA/POLYANILINE CORE/SHELL NANO PARTICLE AND APPLICATION TO THE PSEUDO CAPACITOR VIA SOLUTION PROCESS

摘要

The present invention silica in the water phase and the organic phase boundary at low temperatures - cresol (meta-cresol) and chloroform _(CHCl 3) - polyaniline core-shell silica manufacturing and Nanoparticles - polyaniline core meta-shell nanoparticles high conductivity used as a co-solvent (600 to 700 S / cm) as pseudo capacitors prepared as a thin film to be made to the application of the (pseudo capacitor or redox capacitor or super capacitor), by introducing the conductive polymer to the inorganic by using a low temperature interfacial polymerization reported on existing silica-polyaniline core-shell nanoparticles having a conductivity (22 to 26 S / cm) rises above 10 times the silica-polyaniline core-silica produced and a method for producing a shell nanoparticle-Polyaniline core-shell after the nanoparticles dedoping with a strong base solution, relatively organic acid is a secondary doping of the large size (secondary doping) the silica-polyaniline core-shell nanoparticles, the organic solution was highly conductive thin film (600 to 700 S / cm) and provide a method for manufacturing electrodes used in cases when high capacitance (1560 F / g) and 3000 seconds charge / discharge efficiency of 99% or less kalba Medtronic maintains that show the performance of the next generation of capacitor electrodes was presented as a possibility. According to the invention, a simple and previously reported by the low interfacial polymerization silica-polyaniline core-shell nanoparticles than 10 times the conductivity (22 to 26 S / cm) of silica having a - polyaniline core-shell nanoparticles and silica-polyaniline core - has the advantage that can be easily produced a shell nanoparticle thin film in large quantities. Further, the silica, which may be prepared in the present invention polyaniline core-shell nanoparticles is not only not be tied to the size of the silica particles, the prepared silica-polyaniline core-shell nano-chairs and silica-polyaniline core-shell nano particle thin film has a high reproducibility (within 99% margin of error) in the conductivity and capacitance. ;
