PAA can be used for a variety of applications such as:
a surfactant in the formation of photonic crystals
a binder for the development of Silicon anode based lithium ion batteries
polyelectrolyte membranes for electronics and optoelectronics based applications
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. It has a high ion exchange capacity that makes it useful in the development of membranes.
