Model for the permeability of functionalised solutes in polymers above the glass transition involving specific interactions
چکیده انگلیسی
Dye diffusion thermal transfer printing involves the transport of dyes from a dye-donor film to a dye-acceptor film at high temperature, well above the glass transition of most amorphous polymers. A model has been developed for the transport of a fixed dye solute from a common dye-donor. Using the solution-diffusion model of permeability as a starting point, equations have been developed to correlate solute permeability with dye and dye-acceptor polymer structural characteristics. In this analysis, diffusivity is controlled by polymer Tg, whereas solubility is controlled by the balance of endothermic physical forces and exothermic specific interactions between dye and dye-acceptor polymer.
