Chemical Solution Deposition of Al(OH)3‐AlOOH Films: Application for Surface Sensitizing of Rigid and Flexible Substrates to Improve the Adhesion in Coating Technology Areas

“…Given the above, and given our previous experience, we decided to use aluminum oxide (Al 2 O 3 ) material deposited by radio‐frequency sputtering [24] to test the effects of adhesion. However, our recent line of research is oriented to the utilization of non‐vacuum techniques, and to better employ equipment, tools, and reagents that are available in most research laboratories, and to follow methodologies that can be carried out under typical lab conditions [21,22,25‐31] . In this sense, in the present work, we present a simple and practical formulation to obtain adherent and homogeneous thin films of an aluminum compound (in fact, a mixture of aluminum hydroxide, Al(OH) 3 , and aluminum oxyhydroxide, AlOOH, as will be demonstrated latter) by chemical solution deposition, which is a “wet” technique that is well known for its simplicity, versatility, reproducibility, low cost, large‐scale and industry compatibility, among many others advantages over physical techniques [15] .…”

[15] Perhaps this is the main contribution of the present research, since there are only three works that deal with aqueous formulations to deposit thin films of aluminum Images at the left correspond to the appearance of the samples at the moment that are withdrawn from the reaction solutions, while the right images correspond to the samples after the cleaning process with water and wet cotton.…”
