# Covalent Crosslinking of Porous Poly(Ionic Liquid) Membrane via a Triazine Network

## TL;DR

This paper presents a method to enhance porous poly(ionic liquid) membranes by covalently cross-linking them with a triazine network, improving stability without altering pore structure, thus broadening their operational environment.

## Contribution

It introduces a covalent cross-linking technique for porous poly(ionic liquid) membranes that maintains pore structure while increasing environmental stability.

## Key findings

- Covalent cross-linking does not change pore size or distribution.
- Membranes become more stable in high ionic strength salt solutions.
- The method broadens the operational environment of the membranes.

## Abstract

Porous poly(ionic liquid) membranes that were prepared via electrostatic cross-linking were subsequently covalently cross-linked via formation of a 1,3,5-triazine network. The additional covalent cross-links do not affect the pore size and pore size distribution of the membranes and stabilize them towards salt solutions of high ionic strength, enabling the membranes to work in a broader environmental window.
