Zusammenfassung: | The invention discloses a fluorinated super-crosslinked polymer as well as a preparation method and application thereof. The preparation method comprises the following steps: dispersing a monomer containing an aromatic ring and/or a polymer containing an aromatic ring in halogenated fluoroalkane to obtain a mixed solution, adding Lewis acid, carrying out Friedel-Crafts alkylation reaction to obtain a crude product, and separating and purifying the crude product to obtain a fluorinated super-crosslinked polymer; wherein the halogenated fluoroalkane is used as a solvent and a cross-linking agent, and the halogenated fluoroalkane is alkane containing at least one fluorine and at least one non-fluorine halogen. Halogenated fluoroalkane with an adjustable chemical structure is selected as a cross-linking agent and is subjected to Friedel-Crafts alkylation condensation polymerization with a monomer and/or a polymer containing an aromatic ring, so that the fluorine atom functionalized super-crosslinked polymer is si |
