The workshop covers in-depth Dynamic Vapor Sorption (DVS) technology and its applications on studies of materials such as polymers, membranes, porous materials, thin films, and so on. Polymers are widely used in various fields such as Energy and Environmental, Automotive and Aerospace, Marine and Biomedical amongst many other areas and DVS technique can provide insights into a variety of properties.

Assoc. Prof. Catarina Esteves at Eindhoven University of Technology researches polymers & colloids, surfaces & interfaces. A large part of her work involves the design of “Smart Coatings” which have self-healing, self-cleaning, and stimuli responsive properties, as well as special wettability and anti-fouling, for end-applications in the automotive, aerospace, marine and biomedical fields. We are pleased to have her give a short presentation on the role of DVS in her research work.

This workshop is beneficial to individuals who work in the areas of:

  • Polymers
  • Membranes
  • Porous Materials (of polymeric nature)
  • Coatings and thin films
  • Packaging Materials

In the workshop, you will learn about:

  • Capability of DVS technology and its applications in various industries
  • Overview of benefits when coupled with different microscopic and spectroscopic techniques (Raman/NIR/video camera)
  • Some examples and case studies for
    • Sorption isotherms and BET surface area
    • Vapour-induced phase changes (glass transition temperature and critical RH)
    • Vapour permeability and diffusion in porous materials and membranes


  • Introduction to Surface Measurement Systems
  • DVS – Introduction and Basic Applications
  • Vapour permeability in porous materials (particularly membranes and thin polymer films)
  • Role of DVS in our research group and examples of materials we analyse – by Assoc. Prof. Catarina Esteves
  • Instrument and Software demonstration
