Abstract
Thermal response of cross-linked poly (N-isopropylacrylamide) (NIPAAm) gel grafted on a single ion track in poly (ethylenterephthalate) (PET ) was investigated using electrical conductivity. The graft layer shri nked above 31 degrees C resulting in an increase of current through th e pore. The technique enables detailed swelling and shrinking studies in grafted single-ion tracks including a precise determination of volu me phase transition temperatures. In this way a basis for experiments with large organic molecules relevant to drug release is established.
