This book provides readers with an understanding of how to control the properties and functionality of surfaces and interfaces by modifying them with polymers. The key to the success of this procedure is to be able to place the correct polymer in the correct amount at the interface to obtain those desired properties. The author presents a concise description of the current methods to design, examine, produce, and predict the properties of these polymer-modified interfaces, as well as promising future technologies and outstanding hurdles and questions.
