Abstract

The invention relates to a process method for a thermoplastic soft magnetic supramolecular material assembled by complexing a subject and an object, which belongs to the field of magnetic materials and high molecular materials. The invention relates to a subject provider which is formed by the complex assembly of a tetrafluoroethylene and a perfluoro-n-propyl-vinyl ether copolymer as the subject and the object of the supramolecular material; under the conditions of high temperature and high pressure, a subject-object complex assembled system is formed by absorbing cations or soft magnetic nanometer granules with polarities. After the complex assembly of the subject and the object is completed, washing and drying are carried out, and finally, secondary granulation is carried out by utilizing a vacuum double-screw extrusion machine so as to split a terminal group; and the extruded granules are the thermoplastic soft magnetic supramolecular material product assembled by complexing the subject and the object. The thermoplastic soft magnetic supramolecular material product disclosed by the invention has the advantages of customized magnetic conductive performance, superior electrical performance, fine mechanical performance, fine processability, chemical resistance and thermostability.

Description

technical field [0001] The invention relates to a process method for host-guest complexation assembly of thermoplastic soft magnetic supramolecular materials, which belongs to the field of magnetic materials and polymer materials. Background technique [0002] Supramolecular synthetic chemistry is penetrating into many disciplines such as organic and polymer synthesis, new material technology, biology and bionics, especially in the preparation and synthesis of intelligent functional materials and molecular devices, supramolecular construction and immobilization have become an important way . Compared with traditional polymer synthesis, supramolecular synthesis has the following advantages: (1) Through non-covalent bonding, it is easy to form an ordered structure, and then immobilized to obtain a highly ordered structure similar to biosynthesis; (2) Supramolecular construction can obtain composite polymer systems that cannot be constructed by covalent bond reactions, such as...
