Certain pitches can be spun directly into isotropic pitch fibers with only minor devolitization. Carbonized isotropic pitch fibers cannot be graphitized and develop mechanical and thermal properties that are substantially inferior to those produced by other precursors. However, isotropic pitch fibers are very inexpensive and have found commercial applications in areas that do not require the exceptional mechanical and thermal properties of mesophase pitch-based carbon fibers. Isotropic pitch-based carbon fibers are used in filters, brake pads, activated carbons, and as substrates for chemical vapor deposition (23). Table 3 summarizes properties of isotropic pitch-based carbon fibers. 

Carbon nanotubes have attracted huge attention ever since they were discovered because of their unique structures. The studies are mainly focused on the mechanical, electrical, and thermal properties of carbon nanotubes and the applications of their novel properties. Fluid behavior inside carbon nanotubes and fluid transport through carbon nanotubes have been investigated only recently and novel fluidic phenomena, such as abnormally low flow resistance, have been observed. Carbon nanotubes are usually synthesized by arc-discharge, laser ablation, and Chemical Vapor Deposition (CVD) [4]. The arc-discharge and laser ablation methods involve the condensation of carbon...
