摘要：A highly homogeneous polyaniline/titanium oxide hybrid, which contains approximately 75% polyaniline by mass, has been prepared by the oxidative polymerization of aniline with the simultaneous hydrolysis of Ti(SO(4))(2). As an electrode material for electrochemical capacitors, its initial specific capacitance is about 495 F g(-1) within the potential window -0.2 to 0.7 V vs. SCE at a constant current density of 2.5 A g(-1), and its capacitance retention ratio reaches circa 70% with the growth of current densities from 0.5 A g(-1) to 30 A g(-1). It is promising for high-rate electrochemical capacitive energy storage.
