20th- to 21st-Century Technological Challenges in Soft Coatings
Robert R. Matheson Jr.
Coatings are among the most ancient technologies of
humankind. Relatively soft coatings comprising organic materials such as blood, eggs, and extracts from plants were in use more than 20,000 years ago, and coating activity has been continuously practiced since
then with gradually improving materials and application techniques. The
fundamental purposes of protecting and/or decorating substrates have
remained ubiquitous across all the centuries and cultures of
civilization. This article attempts to extrapolate the long tale of
change in soft coating technology from its current state by identifying
some key problems that attract research and development efforts as our
21st century begins.
