Abstract

The invention discloses a polyvinyl chloride elastomer electroosmosis electrode composite material. The polyvinyl chloride elastomer electroosmosis electrode composite material is prepared from the following components in percentage by mass: 31 to 35 percent of a polyvinyl chloride elastomer, 6 to 10 percent of a phenoxy resin, 6 to 10 percent of an epoxy resin, 6 to 10 percent of a cosolvent, 1 to 3 percent of a curing agent, 1 to 3 percent of a coupling agent and the balance of conductive carbon black. The invention also discloses a preparation method of the polyvinyl chloride elastomer electroosmosis electrode composite material. The polyvinyl chloride elastomer electroosmosis electrode composite material disclosed by the invention has good mechanical properties such as flexibility, adhesion and the like, meanwhile, due to the addition of the cosolvent, the conductivity is excellent when the polyvinyl chloride elastomer electroosmosis electrode composite material is used for an electroosmosis electrode, the resistivity of a product is not attenuated after long-time energization, and the stability is high. The preparation method of the polyvinyl chloride elastomer electroosmosiselectrode composite material is basically the same as that of a common polymer material in processing and forming, so that the preparation is convenient, the practicability is high and the market prospect is wide.

Description

technical field [0001] The invention belongs to the technical field of electroosmotic electrode materials, in particular to a polyvinyl chloride elastomer electroosmotic electrode composite material, and the invention also relates to a preparation method of the above-mentioned polyvinyl chloride elastomer electroosmotic electrode composite material. Background technique [0002] According to the difference of structure and preparation method, conductive polymer materials can be divided into two categories: structural conductive polymer materials and composite conductive polymer materials. Structural conductive polymer materials refer to conjugated polymers whose molecular structure itself can conduct electricity or have a conductive function after doping treatment, such as polyethylene fast, polyaniline, polypyrrole, polyphene, polyfuran, etc. Composite conductive polymer material refers to the polymer as the matrix, by adding various conductive fillers (such as carbon black...
