pH/Temperature dependent phase transition of an interpenetrating polymer network: Anomalous swelling behavior above lower critical solution temperature
Anomalous swelling behavior has been observed in interpenetrating polymer networks (IPNs) gel composed of poly ( N-isopropylacrylamide) (PNIPAM) and poly(acrylic acid) (PAA). Calorimetric endotherms, FT-IR (Fourier transform-infrared) spectra and compression modulus show that the molecular interacti...

Summary: | Anomalous swelling behavior has been observed in interpenetrating polymer networks (IPNs) gel composed of poly (
N-isopropylacrylamide) (PNIPAM) and poly(acrylic acid) (PAA). Calorimetric endotherms, FT-IR (Fourier transform-infrared) spectra and compression modulus show that the molecular interaction such as hydrogen bond and hydrophobic interaction serve as a driving force which takes place with an anomalous swelling behavior. |
