Fluorophenyl cross-linked polyaryl piperidine-based ionic polymer, and preparation method and application thereof

Abstract

This invention provides an ionic polymer based on fluorophenyl crosslinked polyarylpiperidine, its preparation method, and its applications, belonging to the field of polymer materials technology. The preparation method includes the following steps: placing a fluorophenyl crosslinking agent, an N-substituted R-4-piperidine, a ketone reactant, and an aromatic reactant in a first organic solvent, adding an acid catalyst to react and obtain a polymer solution with a piperidine structure; subsequently, washing, filtering, and drying in a first precipitant to obtain a polymer powder with a piperidine structure; then dissolving it in a second organic solvent, adding a methylating agent and a basic reagent to react and obtain a quaternized polymer solution; subsequently adding it to a second precipitant, washing, filtering, and drying to obtain an ionic polymer containing fluorophenyl crosslinked polyarylpiperidine. This invention provides a simple preparation method with low raw material costs and is suitable for large-scale production, applicable to fields such as water electrolysis.
