Preparation method of poly-3,4-ethylene dioxythiophene and compound arrays thereof

Abstract

The invention relates to a preparation method of poly-3,4-ethylene dioxythiophene and compound arrays thereof. Porous materials capable of being easily obtained are adopted as templates, poly-3,4-ethylene dioxythiophene and monomers or oxidizing agents of the compound of the poly-3,4-ethylene dioxythiophene are enriched in pores through chemical engineering reinforcement measures such as supergravity fields, vacuum filtration, surface treatment and the like, the templates are removed after the polymerization reaction, arrays consisting of fibers or pipes are obtained, the density, the thickness, the fiber diameter, the pipe diameter, the pipe wall, the pipe distribution, the structure, the appearance and the like of polymer arrays are regulated through controlling template pore structure parameters and reinforcement technological parameters, and the controllable preparation of polymer array materials is realized. The preparation method has the advantages that the interphase mass transfer process is enhanced, the contact between reactant precursors is enhanced, the filling rate of the template pore inside the template holes is improved, the array defects are few, the surface is flat and smooth, the pipe wall is easy to control, the preparation efficiency of the array materials is high, the array density is high, the reaction is easy to operate, the preparation method process issimple, the cost is low, the investment is little, the benefits are good, the industrial production is easy, and the preparation method is suitable for the scale low-cost production of three-dimensional array materials with few defects and high density.

Description

Technical field [0001] The present invention involves the preparation method of gathering 3,4-BFiles and its complex array. Coupling chemical enhanced measures form arrays in their original positions in the hole templates.

AI Technical Summary

Problems solved by technology

Array materials have a three-dimensional structure with a high specific area, which is conducive to the full contact and mass transfer of different reaction phases. Prepared in the template hole, not under chemical strengthening measures, the contact between the array material and the hole surface is loose, the filling rate in the hole is not high, the prepared material has poor density, high surface roughness, difficult to control the tube wall, and poor reproducibility And other issues
