Problems solved by technology

For example, Wang et al. (Hollow PAQR nanostructure and its smartelectrorheological activity, polymer, 2016, 83, 129-137) disclosed the use of surfactants such as sodium dodecyl sulfate as templates to synthesize PAQR with hollow sphere structures, but due to sodium lauryl sulfate Dimensional stability is poor, and the obtained PAQR hollow spheres are not uniform in size and easy to break
At the same time, the current synthesis of PAQR has many side reactions and severe monomer volatilization, resulting in low yield

preparation example Construction

[0029] The specific steps of the preparation method include:

[0030] The modified montmorillonite with Lewis acid as the intercalating agent is selected as the template, and the modified montmorillonite, fused-ring aromatic hydrocarbon and acid anhydride are added to the first solvent and mixed evenly; after ultrasonic treatment, suction filtration and drying are performed to obtain the first solid; One solid is heated up and reacted, and after the reaction is completed, it is cooled to room temperature to obtain a second solid; the second solid is purified to obtain the polyquinone polymer.

[0031] As an optional embodiment, the modified montmorillonite uses Lewis acid as an intercalating agent, and the Lewis acid can be selected from quaternary ammonium salt, ZnCl 2 , AlCl 3 , FeCl 3 one of the others. The montmorillonite intercalated with Lewis acid can play the role of template and catalyst at the same time, which makes the reaction efficiency higher and the reaction ...

Description

technical field [0001] The application relates to a polyquinone polymer and a preparation method thereof, belonging to the technical field of chemical synthesis. Background technique [0002] Polyacenequinoneredical polymers (PAQR for short) are intrinsically semiconducting polymers, and the special mobile polarization form in their molecules makes them have a high dielectric constant. A special class of "amphibious" materials. PAQR can not only be used as semiconductive / high dielectric fillers and other matrix polymers to prepare composite polymer materials, but also can be used as pure organic semiconductive / dielectric materials in the fields of sensors and electrical energy storage. At present, the commonly used methods include solid phase melting method, vapor deposition method and solution polymerization method, which are mainly formed by the polymerization of aromatic or heteroaromatic monomers and acid anhydrides under the catalysis of Lewis acid. Under normal circu...
