This study is about preparing different paper substrates with chemically stable hydrophobic and superhydrophobic surface coatings through spraying a mixture of poly(dimethylsiloxane) (PDMS) and inorganic particles. The method is easy to implement, reproducible and requires inexpensive starting materials. Non-colored and colored types of (i) raw paper (UC), (ii) glossy coated paper (GC) and (iii) matte coated paper (MC) surfaces were selected for surface modification through the coating application. Both water-based ink (WB) and solvent-based ink (SB) formulations were used to dye substrate surfaces. Investigations including surface wetting, optical and physical properties of the coated paper substrates revealed that the coating application method proposed is a promising lacquer alternative for packaging purposes.
