【 摘 要 】

References(9)Cited-By(1)The introduction of a fluorine-base polymeric surfactant has showed a 10% enhancement in solvent evaporation rates within a certain range of polymer concentrations in cellulose acetate butyrate (CAB)/methyl ethyl ketone (MEK) solutions. Weight loss measurements have revealed that the drying rate initially increased and subsequently decreased with increasing surfactant mass fractions (P). The normalized drying rates obey a single master curve, and show a peak at a blending ratio of P∼0.1. The results suggest that surfactant addition is a promising method for achieving higher solvent diffusion rates in liquids.
