Ultraconductors are Room temperature superconductors. They are widely considered for large power applications.
Ultraconductors are the result of more than 16 years of scientific research ,independent laboratory testing and eight years of engineering development.
From an engineering perspective, ultraconductors are a fundamentally new and enabling technology. These materials are claimed to conduct electricity at least , times better than gold, silver or copper.
Applications Magnetic-levitation is an application where superconductors perform extremely well. Transport vehicles such as trains can be made to "float" on strong superconducting magnets, virtually eliminating friction between the train and its tracks.
Not only would conventional electromagnets waste much of the electrical energy as heat, they would have to be physically much larger than superconducting magnets. A landmark for the commercial use of MAGLEV technology occurred in when it gained the status of a nationally-funded project in Japan.
Abstract Ultraconductors are Room temperature superconductors.
They exhibit a set of anomalous magnetic and electric properties including very high electrical conductivity and current densities over a wide temperature range. Based on experiment and theory, the total list of candidate polymers suited to the process is believed to number in the hundreds.
A successful candidate polymer must be polar without significant crystalline or glass phase at the time of processing. To date measurements have focused on macroscopic features, specifically, measurements of the magnetic, electric, thermal, chemical, and morphologic nature of the channels.
Magnetic Characterization The processing treatment initiates characteristic changes in the magnetic state of the polymer, as measured in a sensitive Faraday magnetic balance.
The most typical feature is a growing ferromagnetism which precedes the appearance of electrical conductivity. Electric Characterization 3.
In , the Dutch physicist Heike Kamerlingh Onnes discovered superconductivity in mercury at a temperature of approximately 4 K o C. Many other superconducting metals and alloys were subsequently discovered but, until , the highest temperature at which superconducting properties were achieved was around 23 K o C with the niobium-germanium alloy Nb3Ge In George Bednorz and Alex Muller discovered a metal oxide that exhibited superconductivity at the relatively high temperature of 30 K o C.
This led to the discovery of ceramic oxides that super conduct at even higher temperatures. In , and oxide of thallium, calcium, barium and copper Ti2Ca2Ba2Cu3O10 displayed superconductivity at K o C , and, in a family based on copper oxide and mercury attained superconductivity at K o C.
These "high-temperature" superconductors are all the more noteworthy because ceramics are usually extremely good insulators. Like ceramics, most organic compounds are strong insulators; however, some organic materials known as organic synthetic metals do display both conductivity and superconductivity. In the early 's, one such compound was shown to super conduct at approximately 33 K o C.
Although this is well below the temperatures achieved for ceramic oxides, organic superconductors are considered to have great potential for the future. New superconducting materials are being discovered on a regular basis, and the search is on for room temperature superconductors, which, if discovered, are expected to revolutionize electronics.

These materials are claimed to conduct electricity at least , times better than gold, silver or copper.
The materials exhibit a characteristic set of properties including conductivity and current carrying capacity equivalent to superconductors, but without the need for cryogenic support. This transition resembles a formal insulator to conductor I-C transition.
The base polymers used are certain viscous polar elastomers, obtained by polymerization in the laboratory or as purchased from industrial suppliers. Seven chemically distinct polymers have been demonstrated to date. Properties of Ultraconductors Ultraconductors are the electrical conductors which have certain properties similar to present day superconductors.
They are best considered as a novel state of matter. They are made by the sequential processing of amorphous polar dielectric elastomers.
