The specific conditions in which these filaments have grown to macroscopic dimensions have occasionally been accidentally attained. Thus the “chemical

Those familiar with the early literature in this area are still fascinated by the many elegant synthetic routes to high temperature high polymers, examples of which are the polybenzimidazoles, polyoxadiazoles, polybenzothiazoles and poly

Hence, engineers have always desired suffer, stronger, less dense and lower cost structural materials. There are a number of mate

Production of VGCF on a commercial scale has lagged behind expectations for a material with
