Nobel Laureates in Chemistry Hideki Shirakawa, Alan Haig, and Alan McDilmid found that doped polyacetylene has high conductivity (up to 1000 S cm-1), breaking the organic polymer insulation This traditional concept opened up a new era of conductive polymers
.
Conductive polymers have both the mechanical flexibility of traditional polymers and the peculiar optoelectronic properties of metals and semiconductors, and they are easy to prepare, have adjustable conductivity, and have good electrochemical activity

【Controllable Synthesis Strategy of Porous Conductive Polymer Nanostructured Materials】

This paper first introduced and analyzed the advantageous physicochemical properties and unique structural characteristics of nanostructured porous conductive polymers, and combed the current synthesis strategies of nanostructured porous conductive polymers, including template method (hard template, soft template) and no Template method, and the main characteristics of each method
.
The template-oriented construction method utilizes the spatial confinement of the template to regulate the physical and chemical reactions during the preparation process to realize the controllable preparation of materials

.

The template-free regulation avoids the use of templates, and the introduction of its pore structure comes from structural defects spontaneously generated during the growth and aggregation of nano-scale polymer units
.
Therefore, compared with the template method, the template-free method has poorer controllability for preparing porous conductive polymers

【Application of porous conductive polymer nanostructure materials】

Conductive polymers have their own unique molecular structure, excellent conductivity, and good redox electrochemical performance.
Secondly, the introduction of an open porous network structure is conducive to shortening the mass transfer path, effectively increasing the contact area and exposing more The surface reaction active sites, so it is favored in the fields of energy storage conversion, sensing and so on
.
Therefore, this paper focuses on the potential applications of a series of representative porous conductive polymer nanostructure materials in batteries, supercapacitors, sensors and other directions (such as flexible electronics, CO2 adsorption, biomedicine, pollutant removal, etc.
