“…The lubricant treatment improved the friction properties and surface structuring had a great effect on the water contact angle. The common targets of modification of plastic surfaces were to develop new plasticizers and mixtures (Bohnert et al 1998, Puukilainen and Pakkanen 2005, Koponen et al 2007a, and to modify hydrophobic properties (Fresnais et al 2006, Li et al 2006, Puukilainen et al 2006, Koponen et al 2007b) and surface structures (Li et al 2006, Puukilainen et al 2006, Koponen et al 2007b. Surface structure was reported to affect the hydrophobic properties (Fresnais et al 2006, Li et al 2006, Koponen et al 2007b).…”
