The macroscopic volume shrinkage and swelling of poly (N-isopropylacrylamide) (PNIPA) gel induced by the compositional change in the methanol-water mixed solvent is correlated to the change in the nanoscopic free volume size and numerical concentration formed in the PNIPA gels. The free volume size
