Description
Technical Field
The application relates to a Duoconjin polymer and a preparation method thereof, belonging to the technical field of chemical synthesis.
Background
Polygenic quinonoid polymers (PAQR for short) are intrinsic semiconductive high-molecular polymers, and have a special swimming polarization form in the molecule, so that the polygenic quinonoid polymers have a high dielectric constant and are special amphibious materials. The PAQR can be used as a semiconductive/high dielectric filler to be compounded with other matrix polymers to prepare a composite polymer material, and can also be used as a pure organic semiconductive/dielectric material to be applied to the fields of sensors and electric energy storage. The method commonly used at present comprises a solid-phase melting method, a vapor deposition method and a solution polymerization method, and is mainly prepared by polymerizing aromatic ring or heteroaromatic ring monomers and acid anhydride under the catalysis of Lewis acid. Under normal conditions, polymer chains generated in the free polymerization process are difficult to be folded and arranged in an ordered direction in a three-dimensional space, are generally intertwined, have no regularity, and the synthesized PAQR is mostly in an irregular shape. For example, Wang et al (Hollow PAQR nanostructure and its smart electrochemical activity, polymer,2016,83,129-137) disclose the synthesis of PAQR in the form of Hollow spheres using a surfactant such as sodium lauryl sulfate as a template, but the size of the resulting PAQR Hollow spheres is not uniform and is easily broken due to the poor dimensional stability of sodium lauryl sulfate. Meanwhile, the yield is low due to more side reactions and serious monomer volatilization in the current PAQR synthesis. Therefore, the realization of the controllable preparation of the PAQR morphology and the improvement of the yield are the difficulties which need to be broken through urgently in the prior art.
