Maiju Pykönen (PhD) from Attension will be giving a talk on "Experimental Comparison of Wettability of Pico- and Microliter Droplets with Range of Liquid Surface Tensions on Porous and Non-Porous Substrates" at the forthcoming NIP conference (International Conference on Digital Printing Technologies) in Quebec City, Canada, which take place from the 9th to the 13th of September 2012.
Come listen to Maiju and get a chance to ask your questions on her research and on how to overcome technical challenges when working with droplet sizes and wettability. Please find below a small description of the talk.
Title: Experimental Comparison of Wettability of Pico- and Microliter Droplets with Range of Liquid Surface Tensions on Porous and Non-Porous Substrates
In recent years, the interest towards to the picoliter droplets has increased due to emerging inkjet technology and due to need to analyze wettability of novel micropatterned surfaces. Discussion about the effects of droplet size on contact angle has broadened to compare microliter droplets to picoliter droplets as microliter droplets are typically utilized in contact angle measurements. Influence of gravity on the droplet and the rate of the drop size reduction due to evaporation are the two major differences between pico- and microliter droplets. In this study pico- and microliter droplets contact angle values were compared on non-porous and porous substrates by using wide range of different surface tension liquids to broaden the understanding of droplet volume’s effect on contact angle. Contact angles were studied by using the Theta Optical Tensiometer with micro- and picoliter dispensers.
