Agenda

Welcome to Attension User Day 2024!

Attension user day is biennial online event we organize with the aim of bringing all our Attension tensiometer users together. During the event, our goal is to exchange knowledge and insights with current and future users on popular industry topics.

This year, Attension® user day is focusing on Basics of Wettability. You will get the opportunity hear insights from both internal & external experts, on how wettability measurements can help with your research and product development. Throughout the session, you will have the chance to engage with us and the invited speakers, sharing your questions. Don´t miss out on this insightful event - Join us!

Susanna-Lauren

Basic of surface tension and contact angle measurements for different industries

Session lead by Susanna Laurén, Marketing Director, Attension & KSV NIMA,  Biolin Scientific

Wettability is often assossiated with adhesion and is thus important in various different industrial applications. Wettability is affected by both the properties of the liquid applied as well as the surface properties of the solid. Surface tension measurements are routinely used to study the wetting ability of the liquids. Contact angle measurements are used to evaluate the wettability of the surfaces. In this talk, basics of surface tension and contact angle measurements are discussed with the help of application examples from industry.

Henni Mäntykangas Round

Advanced wettability measurements

Session lead by Henni Mäntykangas, Application at Biolin Scientific

Sometimes static contac angle measurements are not enough to characterize the wettability of the surface but more advanced methods are needed. In this talk, dynamic contact angle and roughness corrected contact angle measurements are reviewed and examples from industry are presented.  

Amy Peterson Round-1

Interface-Mediated Mechanics of Highly Filled, Additively Manufactured Polymer Composites

Guest speaker: Amy Peterson, Associate Professor and Dandeneau Endowed Professor, Department of Plastics Engineering, University of Massachusetts Lowell

Interfacial adhesion influences mechanical strength, structural integrity, and overall performance for adhesively bonded structures and composite materials. We have investigated the effect of resin formulation chemistry on wetting behavior and interfacial adhesion with a glass substrate and used this knowledge to tailor mechanics of highly filled, additively manufactured composites. We observed that resin wettability, as measured by resin contact angle on the substrate of interest, was most predictive of interfacial adhesion. Additionally, interfacial interactions between the urethane resin system and glass microspheres were found to dictate the overall performance of the composites.


 

Dr. Shihong Lin Round-1

More than just surface tension: the caveats in interpreting contact angles measured using surfactant solutions

Guest speaker: Dr. Shihong Lin, Associate professor and a Chancellor Faculty Fellow in the Department of Civil and Environmental Engineering and the Department of Chemical and Biomolecular Engineering at Vanderbilt University.
