Adhesion Science, Engineering and Technology

Learning objectives

Goal

This course aims to provide students with a fundamental understanding of adhesion mechanisms of organic material to solid surfaces. Furthermore, the physico-chemical interactions will be related to engineering applications, such as coating and adhesive bonding of metals. After the course, the student will be able to address:

  • the character of interfacial bonding at the macro- and microscale
  • different types of interactions between organics and solid surfaces
  • the effect of organic and solid surface chemistry on interfacial bonding
  • failure and degradation mechanisms of interfacial bonding
  • surface treatment for improved initial and durable interfacial bonding
  • techniques to study and assess interfacial bonding
  • engineering design aspects for optimized interfacial bonding

Focus

Special emphasis will be put on the study of coating/adhesive-metal Interactions:

  • basics of metal-coating interface morphology and chemistry
  • polymer and metal surface chemistry effects
  • failure and degradation mechanisms
  • traditional and advanced experimental techniques to study metal-polymer
  • Physical and mechanical properties of adhesive bonding
  • Polymer chemistry
  • Surface chemistry related to adhesion
  • Effect of adhesion on durability and corrosion resistance
  • Unfavourable adhesion phenomena (a.o. contaminations and biofilms)
  • Engineering criteria for adhesive bond design
  • Techniques for adhesion evaluation

Contents

The student should have basic knowledge and interest in:

  • Physical and mechanical properties of materials
  •  General chemistry
  • Organic and physical chemistry
