Pore Structures and Adsorption Properties of Microporous Carbon-Alloyed Fiber

Practical applications of activated carbon fibers ACFs have been developing not only in environmental technologies, but also electronic ones. ACF has gathered much attention from chemistry and. physics due to the characteristic structures and properties. Kaneko et al have been studying the pore structures, micrographitic structures, adsorptive properties, and physical properties with a variety of techniques, which are published as reviews. ACF shows the semiconductivity due to the conjugated π-electronic structures, which are strongly associated with molecular adsorption properties even in case of physical adsorption. If we can introduce the insulative nature in the carbon frame structure, new adsorptive and physical properties of ACF are expected to stimulate the carbon science and technology. One of such approaches to the electronic structure modification should be the alloying by use of doping foreign atoms. Touhara et al showed that fluorination controls the electronic properties of ACF. The alloying of ACF with fluorination should give a valuable guide for development of a new functioned porous carbon fiber.
