Ultra-Thin PVA Membranes for CO2 Transportation

Popis výsledku v původním jazyce

The main aim of the study is to investigate the performance of ultra-thin polymer composite nanofiber-embedded membranes for efficient CO2 transport. To fabricate these membranes, a combination of polyvinyl alcohol (PVA) and a specially selected modifier that supports CO2 transport was used in addition to polyamide 6 nanofiber layer. PVA has excellent film-forming properties, mechanical strength, and low toxicity, making it an ideal choice for sustainable applications. Two membranes with special modifiers were prepared. The material properties of the solution-cast membranes are discussed and compared. Surface morphology characterization was accomplished through scanning electron microscopy (SEM) analyses. Experimental tests were performed to evaluate the CO2 permeability of these new membranes. The data obtained from these tests provide evidence of the successful transport of CO2 through the polymer membrane system. The CO2 permeability was evaluated using special equipment designed specifically for these experiments. In addition, these ultra-thin membranes were characterized as robust, compact, and homogeneous. The development of these advanced vapor permeable non-porous systems with improved properties opens the way to interesting applications in gas separation and CO2 capture processes. These advances are vital in reducing emissions and negative environmental impacts.
