摘要: Teflon AF 2400 films are known to imbibe solvents, making in the presence of solvents less fluorous than they might otherwise be. Herein, we demonstrate that doping with perfluorotripentylamine (Fluorinert FC-70) maintains nature and improves transport selectivity for fluorine-containing organic compounds. Density measurements on FC-70-doped reveal free volume decreases dramatically as dopant concentration increases (0−12 wt %) then approach pure FC-70. Remarkably, from 0 12 % FC-70 have same w/v 2400, indicating fills 2400. This is consistent observed increased storage modulus significant decrease (compared undoped films) solute diffusion coefficients range concentrations. In contrast, at concentrations greater dilutes leading a ...
