Precipitation Dynamics for the Formation of Nylon-6 Polyamide Membranes by Isothermal Precipitation in Water/Formic Acid Solutions
並列摘要
The ternary mass transfer equations that describe the isothermal immersion process for polyamide membrane preparation were solved. To account for the moving boundary conditions, coordinate transformations were performed both for the membrane and the bath regions. Mutual diffusion coefficients between solvent and polymer were measured and used to derive ternary phenomenological coefficients for mass transfer equations. The calculated precipitation times, concentration profiles, and diffusion trajectories were found to agree with the measured light transmittance data and the membrane morphologies presented previously.
