"Fabrication and Control of Porous Structures Via Layer- By-Layer Assembly on PAH/PAA Polyelectrolyte Coatings"

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 the formation of distinctive porous structures. Experimental parameters, specifically temperature gradients from ambient to 60°C, and immersion time were systematically manipulated, enabling the successful generation of porous structures with sizes of 300 nm, 800 nm, 1200 nm, 1600 nm, and 2000 nm.
