Problems solved by technology

In recent years, a large number of scientific researchers have carried out a lot of work on the imitation research of perfluorosulfonic acid-based cation-exchange membranes and their derivative products and achieved certain results, but they have not fundamentally solved the problem of perfluorosulfonic-based cation-exchange membranes. Core problems such as complex production process and high cost of process pollutant treatment; high product prices seriously limit the application and development of IEAP and BEDAM

Abstract

The invention discloses a preparing method for a quaternary ion copolymer-inorganic composite bionic electric driving active material. The preparing method comprises three technology steps of quaternary ion copolymer nano-emulsion preparing, quaternary ion copolymer latex film preparing and quaternary ion copolymer and inorganic electric conduction filler composite electrode layer preparing. The semicontinuous emulsion polymerization technology is adopted for quaternary ion copolymer nano-emulsion preparing, reduced pressure distillation treatment is conducted on reaction monomer, a polymerization inhibitor is removed, low-temperature storage is conducted for later usage, and then the quaternary ion copolymer nano-emulsion is prepared by implementing the polymerization reaction technology. During quaternary ion copolymer latex film preparing, polymer nano-emulsion is slowly poured in a flat bottom groove glass die in the normal-temperature and normal-pressure environment, and a quaternary ion copolymer latex film is prepared. Raw materials for preparing the quaternary ion copolymer-inorganic composite bionic electric driving active material are common and easy to obtain, and the preparing technology is simple and environment-friendly; and the prepared product has the beneficial effects that flexibility and tenacity are combined, the bionic electric driving performance is good, biocompatibility is good, the preparing cost is low, and the application prospects are wide.

Description

technical field [0001] The invention relates to the technical field of preparation of polymer-inorganic composite materials, in particular to a preparation method of a quaternary ion copolymer-inorganic composite biomimetic electric drive active material. Background technique [0002] Bionic electric driving active materials (BEDAM for short) is based on the principle of bionics to simulate biological tissue cells to transmit electrical signals through changes in potential and polarity in the process of life activities to achieve life such as matrix tissue nerve conduction and muscle contraction. Active smart materials, which can realize complex shape changes such as contraction, expansion, and bending of biological tissues under the action of a low-voltage direct current electric field, are widely used in many fields such as artificial organs, medical devices, smart clothing, touch sensors, and bionic robots. At present, the matrix material of BEDAM is mainly ionic electroa...
