Application of radiochemical determination methods in cleanability research of building materials

“…determination of topography (e.g. Koponen et al, 2007;Kuisma et al, 2005a;Kuisma, 2006;Myshkin et al, 1999Myshkin et al, , 2003Peltonen et al, 2004;Shulha et al, 2004;Verran et al, 2000Verran et al, , 2003Whitehead et al, 2004) or wetting properties (e.g. Kuisma et al, 2005b;Kymäläinen et al, 2008;Määttä et al, 2007aMäättä et al, ,b,c, 2008Nimittrakoolchai and Supothina, 2008;PesonenLeinonen et al, 2005).…”

Modifications of surface materials and their effects on cleanability as studied by radiochemical methods

“…Suitable for laboratory studies Benvenuti et al 1999, Minabe et al 2000, Fretwall and Douglas 2001, Tikka et al 2004, Braithwaite et al 2005, Kronberg et al 2007 Atomic Force Microscopy High resolution pictures. Unsuitable for rough surfaces Myshkin et al 1999, Verran et al 2000, Myshkin et al 2003, Verran et al 2003, Peltonen et al 2004, Shulha et al 2004, Whitehead et al 2004, Kuisma et al 2005a, Kuisma 2006, Koponen et al 2007a Confocal Microscopy Minimal sample preparation. Background texture often confuses the detectors.…”

“…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).…”
