Possible superconductivity of oxidized polypropylene around 300 K
Abstract
The conductivity characteristics of oxidized polypropylene films 0.3-100 microns thick on copper or indium substrates was investigated experimentally at 293 K. In this temperature range, the oxidized polypropylene films exhibited a drop in resistance by 9 orders of magnitude down to zero as well as strong diamagnetism that was lost with the application of a magnetic field. It is shown that the conductivity of oxidized polypropylene is of the electron rather than ion nature.
