Dynamics of Incomplete Wetting on Porous Materials

Spreading on and penetration into thin, permeable print media: Application to ink-jet printing

“…Denesuk et al [36] highlight the competition between spreading and liquid infiltration into porous media and predict that, for the most part, the time scales for these competing processes will not overlap.…”

Cellulosic Substrates for Removal of Pollutants from Aqueous Systems: A Review. 3. Spilled Oil and Emulsified Organic Liquids

“…Cassie & Baxter 1944;Denesuk et al 1994 The presence of water on a cellulosic surface may lead to significant swelling of the material, thus providing more volume of pores that can affect wetting and accommodate oil. Payne et al 2012 The presence of water on a cellulosic surface does not necessarily impede spreading of oil on that surface.…”

Spreading and Infiltration of Inkjet-Printed Polymer Solution Droplets on a Porous Substrate

“…The range of viscosities examined was however extremely high (750 cP and up) and the pore size in the glass filters was approximately an order of magnitude larger than that in 3DP formed powder beds, 16-40 and 40-400 µm compared to ∼0.1 µm in 3DP (see Tables 1 and 2). Denesuk et al also examined spreading on a porous substrate (12); however, spreading and infiltration were assumed to occur on very different time scales, and so were examined separately (the droplet size examined in their modeling, 0.027 cm 3 , is much larger than the droplets studied here). Quantitative studies of systems where the spreading and infiltration times are comparable (and thus a coupling between the two processes may exist) are lacking in the literature.…”
