    Functional paper surfaces with adjustable wettability can be fabricated by deposition of nanoparticles in a roll-to-roll liquid flame spray (LFS) process. The TiO2 nanoparticle coating creates a superhydrophobic surface with water CAs exceeding 160°, whereas SiO2 nanoparticle coating creates highly hydrophilic surfaces with water CAs as low as 21°. The superhydrophobicity or hydrophilicity is a result of the combined effect of surface structure and surface chemistry of the nanoparticles. Furthermore, the wettability of the TiO2-nanoparticle coated paper can controlled photocatalytically and adjusted with UV-treatment to any water contact angle between 10° to 160°. In the current work, the abrasion and compression resistance of LFS nanoparticle coated paper was investigated with rotary abrasion testing and calendering. Changes in sample properties were analysed with contact angle measurements, atomic force microscopy and high resolution field-emission scanning electron microscopy (FESEM).
