Effects of Static Contact Angle and Roughness on Rolling Resistance of Droplet
Carbon & Light Materials Application R&D Gropu, KITECH, Jeonju-city, Jellabuk-do 54853, Korea(Received March 14, 2016: Corrected March 21, 2016: Accepted March 25, 2016)초록: 본 연구에서는 소수성 구현을 위한 표면 거칠기가 접촉각과 접촉각 이력에 미치는 영향을 평가하였다. 초발수특성을 극대화하기 위해, 액적이 이동하기 위해 필요한 구름저항력을 제안하였으며, 이에 대한 평가를 통하여 표면에 형성한 패턴이 접촉각 이력 및 구름저항력에 큰 영향을 주는 것을 확인하였다.

Static Water Contact Angle Analysis of Cyclonic Atmospheric Pressure Plasma-Activated Polycarbonate [PDF]
Polycarbonate (PC) films were activated using cyclonic atmospheric pressure plasma. The experimentally measured gas phase temperature was from 30 to 95 °C, demonstrating that this cyclonic atmospheric pressure plasma can treat heat-sensitive polymeric materials at the low temperatures. The surface hydrophilicity changes of cyclonic atmospheric pressure

On the Dynamic Contact Angle in Capillary Flows [PDF]
The displacement of the contact line (CL) between two arbitrary immiscible flowing fluids was modeled. The present model is valid for a wide range of viscosity ratios of the phases. This is while the previously developed models reported in the literature

Research on ice suppression performance of titanium alloy surface induced by nanosecond laser
In this study, grid-patterned titanium surfaces were induced via nanosecond laser under ambient air. Combined with the surface wettability, the ice suppression mechanism of the surface microstructure was analysed by static frost experiments and large ...

Contact angle hysteresis in a microchannel: Statics [PDF]
We study contact angle hysteresis in a chemically heterogeneous microchannel by tracking static meniscus configurations in the microchannel upon varying the volume of liquid. We first construct a graphical force balance similar to a previous approach by Joanny and de Gennes for this system, though here with a straight contact line.
