Method for preparing polyaniline/ruthenium oxide/tin dioxide composite electrode material
The present invention provides a method for preparing a polyaniline/RuO2/SnO2 composite electrode material, including: sputtering a SnO2 film onto a tantalum substrate by a magnetron sputtering method, to form a SnO2 layer; preparing porous-structured RuO2 nanoparticles with a uniform pore size distribution (10-15 nm) by a template method; and embedding polyaniline into the RuO2 nanoparticle matrix by a electrodeposition method, to finally obtain a multilayer-structured polyaniline/RuO2/SnO2 composite electrode material with a specific capacitance value of 680-702 F·g−1 and an excellent cycling charge-discharge performance after it is assembled into an electrochemical capacitor.
