Abstract
An altered free volume state model has been proposed to interpret transport phenomena in diverse media within a unified framework. Its specific application to the interpretation and correlation of data on diffusion in polymer solutions, protein solutions, polymeric gels and blends of polymeric melts has been elaborated. Extensive experimental data from the literature have been analysed within the framework of the model, which confirm its utility. Apart from providing quantitative predictions of the effect of polymer concentration or phase fraction and temperature, the model provides a semiquantitative assessment of the influence of diffusant size and shape, molecular weight of the polymer etc. on diffusional characteristics in the above media.
