Abstract
The application provides a polycoanone polymer and a preparation method thereof, wherein the preparation method comprises the following steps: selecting modified montmorillonite as a template, and polymerizing polycyclic aromatic hydrocarbon and anhydride into the polyconfiguration quinone polymer; the polymer has a nanolamellar structure.
Description
Technical Field
The application relates to a polycoanone polymer and a preparation method thereof, belonging to the technical field of chemical synthesis.
Background
The polycoanone polymer (polyacenequinoneredical polymers, PAQR for short) is an intrinsic semi-conductive high molecular polymer, and the special floating polarization form in the molecule of the polycoanone polymer has higher dielectric constant, so that the polycoanone polymer is a special 'amphibian' material. 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 be used as a pure organic semiconductive/dielectric material to be applied to the fields of sensors and electric energy storage. The methods commonly used at present are a solid-phase melting method, a vapor deposition method and a solution polymerization method, and are mainly prepared by polymerizing aromatic ring or heteroaromatic ring monomers and acid anhydride under the catalysis of Lewis acid. In general, polymer chains generated in the free polymerization process are difficult to fold and arrange along an ordered direction in a three-dimensional space, are generally intertwined, have no regularity, and have irregular morphology. For example, wang et al (Hollow PAQR nanostructure and its smart electrorheological activity, polymer,2016,83,129-137) disclose the synthesis of PAQR in a hollow sphere structure using a surfactant such as sodium dodecyl sulfate as a template, but the obtained PAQR hollow spheres are not uniform in size and are easily broken due to poor dimensional stability of sodium dodecyl sulfate. Meanwhile, the PAQR is synthesized at present, and the side reaction is more, so that the monomer volatilizes seriously, and the yield is lower. Therefore, realizing controllable preparation of PAQR morphology and improving yield at the same time is a difficult point of breaking through in the prior art.
