Porous polyelectrolytes synergistically combine electrostatic charge and high specific surface area

which has important applications in energy

environment

biomedicine and other fields and has been rapidly developed in recent years. Due to its charge and hydrophilicity

methods for preparation of porous polyelectrolytes differ from the traditional porous polymers

and also exhibits unique properties. This review summarizes methods for the preparation of porous polyelectrolytes

including layer-by-layer assembly

block copolymer polyelectrolytes self-assembly

counter anion exchange

poor solvent electrostatic complex

and its applications in environment

energy

biomedicine and catalyst. Lastly

the future research of porous polyelectrolytes is briefly discussed.
