ULTRACONDUCTORS(TM): YES OR NO? Author query: Should the paragraph on Ultraconductors(tm) be deleted as not creditable? Does anyone have a reliable second source?Jim.Callahan,Orlando 10:10, May 3, 2008 (PDT)
"However, some organic polymers exhibit electrical resistance many orders of magnitude lower than the best metallic conductors. And, they do this at room temperature! These ultraconductors™, materials such as oxidized atactic polypropylene (OAPP), do not have zero resistance. But, their enhanced conductivity at ambient temperatures and pressures may actually allow them to compete with superconductors in certain fields. Polypropylene, for example, is normally an insulator. In 1985, however, researchers at the Russian Academy of Sciences discovered that as an oxidized thin-film, polypropylene can have a conductivity 105 to 106 higher than the best refined metals. The Meissner effect - the classic criterion for superconductivity - cannot be observed, as the critical transition temperature appears to be above the point at which the polymer breaks down (>700K). However, strong (giant) diamagnetism has been confirmed.[11]"
I quoted the above paragraph in my original draft but on further research have significant doubts. Please comment.Jim.Callahan,Orlando 10:10, May 3, 2008 (PDT)
