Abstract

This lab explores issues that engineers and scientists face in working with thin film i.e., dealing with two phenomena that work against them: cracking and the coffee ring effect.

This lab will explore the phenomena involved in making thin film coatings. Students will explore the problems that crop up in real- life coating applications, and see how to avoid coffee rings and reduce cracking during the drop-casting deposition of a thin film.
