Poly(N-isopropylacrylamide) (variously abbreviated PNIPA, PNIPAM, PNIPAAm, NIPA, PNIPAA or PNIPAm) is a temperature-responsive polymer that was first synthesized in the 1950s. It can be synthesized from N-isopropylacrylamide which is commercially available. It is synthesized via free-radical polymerization and is readily functionalized making it useful in a variety of applications. PNIPA dissolves in water, however, when these solutions are heated in above their cloud point te… WebMar 30, 2024 · The more reticulated the polymer, the more rigid the material, the less it swells in water, and hence the less it shrinks when heated above the LCST.
