Characterization of polymer films
In this webinar you will learn about frequently used analysis methods for thin polymer films, thick polymer films, and adhesive films. You will find out how scratch tests and indentation testing can determine the adhesion and scratch resistance of polymeric films and paints and how their creep properties can be measured. The surface topography and roughness, but also different mechanical properties such as Young’s modulus and adhesion, can be determined with high precision with atomic force microscopy. With the help of rheological investigations and dynamic mechanical analysis, it is also possible to determine the viscoelastic properties and the influence of temperature and humidity on these bulk properties for both thick polymer films and adhesive tapes. Another method for determining polymer film properties, including their optical properties, is refractometry.
Getting an insight into these analysis methods contributes to a comprehensive understanding of the polymer properties of your thin films, thick films, and adhesive films.
The main topics of this webinar at a glance:
· Understanding surface quality and how it can be influenced
