New mechanism of the formation of superconductive ferromagnetic structures in elastomers without conjugation in the backbones

Abstract

A quantum‐mechanical model of charge condensation is proposed for non‐conjugated polar elastomers It was found that the stability of the bi‐ and multi‐polaron state may be achieved if the dielectrical permeability of the matrix is high enough. It is shown that the multi‐electron unit, called as superplaron, should have a linear structure and possess ferromagnetic properties. The one‐dimensional character of the conductivity of a superpolaron leads to the formation of electron pairs and to the appearance of high temperature superconductivity of superpolarons. A lot of experimental data confirms the real existance of superconductivity at some polar elastomers at 300 K.

Modification of a Charged-Bose-Gas Model for Observed Room-Temperature Superconductivity in Narrow Channels Through Films of Oxidized Atactic Polypropylene

“…Single-walled carbon nanotubes have two orbitallydegenerate and spin-degenerate subbands [54,66]. We assume that this minimum resistance becomes 2R Q /N for triplet superconductivity in nanofilaments with all the spins of a nanofilament in the same direction, as is thought to be the case for OAPP [46,47,48]. We have no reason to assume orbitallydegenerate subbands, and, if all spins are aligned, this also halves the number of current paths.…”

“…Here D m is the dipole moment of a group, v is its volume, G is a shear modulus, and ǫ h is a high-frequency dielectric constant. For many electrons in such a material it is energetically favourable for the polarons to form strings called "superpolarons" [46,47,48]. For superpolarons with a linear concentration of polarons c F , the dipoles point outward in a cylinder of radius ρ = 2R 2 0 c F [48].…”

“…A theory for why conducting channels exist in films of elastomers (materials with very low elastic constants) has been developed by Grigorov and coworkers [46,47,48]. The theory involves the formation of one-dimensional channels with diameters of the order of nanometers due to the formation of "superpolarons", i.e.…”

Three small systems showing probable room-temperature superconductivity

“…The theory of Grigorov and coworkers [23,24,25] for why conducting channels exist in polar elastomers such as OAPP involves an unusual type of polaron where rotatable dipolar groups become aligned within a certain radius towards or away from an excess charge. Also, for a high ratio of static and high-frequency dielectric constants, these polarons can coalesce to form linear strings called superpolarons, and the superpolarons coalesce to form conducting channels.…”
