In situ steady state fluorescence experiments (SSF) were reported during the diffusion of water molecules into PAAm in gels at various temperatures. The fluorescence emission intensities, Ip increased continuously as water molecules diffused into gels. I-sc, scattered light intensities, from the gel was also monitored to detect the variation in the gel structure during diffusion process. Swelling and diffusion experiments were quantified by Li-Tanaka and Fickian models.
