摘要The water content dependence of the free volume in chitosan-based hydrogels was studied using the positron annihilation lifetime spectroscopy (PALS) technique. The dynamic water absorption behavior was correlated with the variation in the mean lifetime (tau(3)) and intensity (I-3) Of the o-Ps component. PALS data suggest that water clusters coexist with individual water molecules at the beginning of swelling. The comparison between the calculated and measured values of tau(3) and I-3 implies that the free volume of the hydrogel network has a great effect on the state of water.
