Conditions for the formation of superconductive polymers and possibilities for their realization

Abstract

General principles of the creation of superconductivity at the polymers are considered. It is shown that high temperature superconductivity may be produced only at really one‐dimensional conducting materials. It is also shown that conjugated polymers cannot have onedimensional conductivity. The new class of nonconjugated polar elastomers is proposed as a perspective one for the creation of high temperature superconductive structures–superpolarons–which appear as a result of internal selfionization of the polymer matrix and a consequent selforganization of free polarons. The practical methods of the formation of superpolarons are shown for the films of oxidized atactice polypropylene. Evidences are given which show the existence of superconductive structures in oxidized polypropylene at room temperature.

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.…”

“…In an elastomer (a material with very low elastic moduli) containing rotatable groups of atoms with electric dipole moments, an excess electron causes all dipoles to point away from the electron within a radius R 0 given by [46] …”

“…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.…”
