Application

Poly(vinylsulfonicacid, sodium salt) (PVSA) can be used:

  • In the preparation of superabsorbent semi-IPN (interpenetrating polymer network) hydrogel.
  • As a solid electrolyte for proton conduction in the fabrication of an all-solid-supercapacitor.
  • As a crystallization controlling agent in the preparation of high-quality crystals of porous coordination polymers(CP). PVSA regulates not only the size and structure of the crystals but also their preference orientation, resulting in CP channel alignment in the bulk powdery state.
