DOI: 10.1021/acsomega.4c08891
Abstract: It remains, as yet, far from satisfactory to account for the explicit role of the solvent effect on the transport behaviors of various polymer solutions, especially depending upon the polymer concentration. Here, we exploit the… read more here.

DOI: 10.1515/polyeng-2018-0047
Abstract: Abstract Diffusion of penetrants in polyethylene below the melt temperature is heavily dependent on the crystallinity of the polyethylene, the temperature of the experiment, and the concentration of solvent in the polymer. As the crystallinity… read more here.
