This work is dedicated to the synthesis and comprehensive characterization of cellulose triacetate (CTA) membranes through the non-solvent induced phase separation (NIPS) technique. The main objective is to identify the characteristics of the synthesized membranes and specifically investigate the distinct evaporation times that affect the development of an asymmetric substructure in cellulose acetate (CA) membranes. The research further endeavors to elucidate the mechanisms governing skin formation, aiming to understand the consequential effects of these dynamics on membrane morphology and porosity. Analytical methodologies, including Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and viscosity measurements, are employed to conduct an in-depth examination of the CTA membranes. This study contributes substantively to the scholarly discourse on membrane technology, providing nuanced insights into its applications across diverse industrial domains.
