  题 目:Liquid-repellent surfaces

  时 间:2016年5月17日(周二)上午10:00

  地 点:沙河校区通信楼818会议室

  主讲人:Prof. Hans-Jürgen Butt

  摘 要:

  In the last two decades significant progress has been made in the preparation of surfaces which strongly repel liquids. This advancement is based on a better understanding of the underlying physical principles. Super liquid-repellency can be achieved by nano- and microstructuring a low energy surface in such a way, that protrusions entrap air under­neath the liquid. The fundamental principles, preparation methods and potential applications of super liquid repellent surfaces are described. However, also challenges and fundamental limits will be discussed.

  Prof.Hans-Jürgen Butt studied physics at the Universities of Hamburg and Göttingen. He re­ceived his Diploma in 1986. Then he moved to Frankfurt to work in Bamberg's group at the Max Planck Institute for Biophysics on light induced proton transport of bacteriorhodopsin. After his PhD in 1989 as a postdoc in Santa Barbara with Paul Hansma he got into contact with the newly developed atomic force microscope. From 1990-1996 back in Frankfurt as a researcher he studied biological objects with the atomic force microscope. In this period the work on surfaces in particular on surface forces became a central issue. In 1996 he went to the institute for physical chemistry at the Johannes Gutenberg-University in Mainz as associate professor. There he focussed on the physics and chemistry of interfaces. Three years later he joined the University of Siegen as full professor for physical chemistry. In 2002 join the Max Planck Institute for Polymer Research in Mainz as a director. Prof.Hans Jurgen Butt has published more than 400 research papers, and now he is the President-elect of International Association of Colloid and Interface Scientists.
