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.[1][2][3]

Application

PAA can be used for a variety of applications such as:
  • a surfactant in the formation of photonic crystals[4]
  • a binder for the development of Silicon anode based lithium ion batteries[5]
  • polyelectrolyte membranes for electronics and optoelectronics based applications[6]

Nitroblue Tetrazolium (NBT) is used with the alkaline phosphatase substrate 5-Bromo- 4-Chloro-3-Indolyl Phosphate (BCIP) in western blotting and immunohistological staining procedures. These substrate systems produce an insoluble NBT diformazan end product that is blue to purple in color and can be observed visually.
