Utilizing Layer-by-Layer (LbL) assembly, a fabrication method for the controlled creation of porous structures on Polyallylamine Hydrochloride (PAH) and Polyacrylic Acid (PAA) coatings was developed. These LbL coatings, generated through an acid corrosion process, resulted in formation distinctive structures. Experimental parameters, specifically temperature gradients from ambient to 60°C, imme...
