FINAL PROGRAM



FIFTH INTERNATIONAL SYMPOSIUM ON CONTACT ANGLE, WETTABILITY AND ADHESION



Toronto, Canada; June 21-23, 2006

In his opening remarks at the first symposium in this series Professor Robert Good pointed out that Galileo in the 17th century was quite likely the first investigator to observe contact angle behavior with his experiment of floating thin gold leaf on top of a water surface. Since that time contact angle measurements have found wide application as a method of determining the energetics of surfaces. This, in turn, has a profound effect on the wettability and adhesion of liquids and coatings to surfaces. This symposium is concerned with both the fundamental and applied aspects of contact angle measurements. Issues such as the applicability and validity of various measurement techniques and the proper theoretical framework for the analysis of contact angle data will be of prime concern. In addition, a host of applications of the contact angle technique will be explored including but not limited to: wettability of powders, fibers, wood products, inks, paper, polymers and monolayers. Further focus will be on the use of contact angle data in evaluating surface modification procedures, determining relevance of wettability to adhesion, the role of wettability in bioadhesion, ophthalmology, prosthesis and in the control of dust in mining and milling applications. The primary focus of this symposium is to provide a forum for the discussion of cutting edge advancements in the field and to review and consolidate the accomplishments which have been achieved thus far.

Finally, it is apropos that this meeting is being held back to back with the TENTH INTERNATIONAL SYMPOSIUM ON PARTICLES ON SURFACES: DETECTION, ADHESION AND REMOVAL. Both of these symposia share a common and critical interest in the surface free energy of solid materials. The particle removal investigator knows this quantity strongly affects particle adhesion and for the contact angle person it is one of the prime measurement objectives. Thus on Wednesday the 21st we plan to bring both groups together for a joint session with papers of interest to both camps. It is hoped that a cross-fertilization of ideas will lead to insights of mutual benefit to all. The following is the list of papers to be presented at this meeting. Please note that the address given may apply only to the presenting author.
