摘要：
Anomalous swelling behavior has been observed in interpenetrating polymer networks (IPNs) gel composed of poly (N-isopropylacrylamide) (PNIPAIM) 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.
