In this study, optimized polymeric functional coatings were successfully developed using advanced manufacturing techniques, specifically electrospinning. An exhaustive optimization process was carried out to eliminate defects in surface morphology by precisely controlling parameters such as the flow rate, applied voltage, and the ratio of solvent to precursors. Small variations in these parameters significantly influenced the final quality of the coatings.

The main precursors used were polyaniline (PANI), polyethylene oxide (PEO), and camphorsulfonic acid (CSA), with chloroform serving as the solvent. Additionally, titanium dioxide (TiO₂) was incorporated as a functional additive to enable photocatalytic activity.

To evaluate the photocatalytic performance, a solution containing methylene blue (a model organic pollutant), distilled water, and the functionalized coating was prepared. This solution was exposed to visible light for one hour. Absorbance measurements were taken before and after exposure using UV-Vis spectroscopy, enabling quantification of methylene blue degradation. The observed decrease in absorbance confirmed the photocatalytic degradation of the organic compound.

This research highlights the potential of electrospun polymeric coatings as effective materials for environmental applications, particularly with regard to reducing the quantity of organic pollutants in water. The combination of conductive polymers and photocatalytic additives offers a promising route for the development of smart coatings aimed at environmental remediation. These materials contribute to achieving several United Nations Sustainable Development Goals: Goal 6 (Clean Water and Sanitation), Goal 13 (Climate Action), Goal 14 (Life Below Water), and Goal 15 (Life on Land).
