Abstract
A NanoScratch methodology was used to evaluate the relative adhesive and cohesive strength of fluorinated poly(methyl methacrylate-co-methacrylic acid) and fluorinated phosphate coatings on stone and tile surfaces. In general, all coatings showed ability to bind to the stone and tile surfaces, and polymer-based coatings expressed stronger adhesion compared to a small-molecule fluorinated phosphate coating. Also, anionic fluorinated polymers containing methacrylic acid (MAA) residues in the ammonium carboxylate form adhered more strongly compared to corresponding acidic polymer counterparts. In addition, anionic fluorinated polymers, shown to adhere more strongly to granite than marble, possibly due to strong Lewis acid-base interaction between carboxylate and aluminosilicates. Conversely, the fluorinated polymers, bearing the MAA side-chains in their free-acid form, bound more strongly to marble via possible Brønsted acid-base interactions between carboxylic acid and calcium carbonate. Lastly, in most cases, comparable fracture thresholds were observed for the same coating material on different substrates. This was expected since fracture threshold is a measure of the mechanical strength of the coating material, independent of the substrate difference.
