Deposition of poly(methyl methacrylate) and composites containing bioceramics and bioglass by dip coating using isopropanol-water co-solvent

•Poly(methyl methacrylate) (PMMA) coatings were obtained by a dip coating method.•Isopropanol-water co-solvent was used and eliminated the use of toxic solvents.•PMMA coatings provided corrosion protection of stainless steel.•Composite coatings were obtained containing bioceramics and bioglass in PMMA.•Composite coatings provided enhanced corrosion protection.
