General description
Poly(acrylic acid) solution (PAA) is an anionic polymer that can be synthesized by the free radical polymerization of acrylic acid. It has a swelling nature that tends to absorb and retain the water. Its high ion exchange capacity makes it useful in the formation of membranes.
Application
PAA can be used for a variety of applications such as gas sensors, electrical devices, and cosmetics.
