Description

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. It has a high ion exchange capacity that makes it useful in the development of membranes.

Application

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

Packaging

100 g in poly bottle
