Abstract

The present invention discloses superconductive metal macromolecular composite material which is characterized in that the resistance rate of the composite material is reduced greatly along with the increase of the borne pressure; filling body is the superconductor of oxide or the superconductor of the oxide and very little hardly oxygenated metal powder, which has stable conductivity and longer service life, and the disruptive field intensity is not less than 6 multiplying 10 <5> V / m; superconductive macromolecular composite material has certain magnetic suspension effect at a liquid nitrogen temperature range.

Description

Technical field: [0001] The invention relates to a pressure-sensitive conductive composite material that is sensitive to pressure, resistant to high voltage, and has a certain magnetic levitation phenomenon in the liquid nitrogen temperature zone, in particular to a pressure-sensitive superconducting-metal-polymer composite material and its preparation method . Background technique: [0002] In 1998, the British Peratech company developed a pressure-sensitive conductive rubber material QTC and applied for a patent. The patent application number is PCT / GB98 / 00206. In 2006, the School of Physics and Information Engineering of Henan Normal University successfully developed a new type The pressure-sensitive conductive rubber and applied for a patent in August 2007, and its patent application number is 20071004951.7. The successful development of QTC and new pressure-sensitive conductive rubber has played an important role in the application of pressure-sensitive conductive rubb...
