Introduction to coatings and surface preparation

In this chapter, we would like to discuss polymer coating's know-how, which is a method of modifying surface qualities in order to satisfy operating requirements in a number of technological applications. In addition to adhesion and barrier capabilities, polymer coatings have also been used to improve scratch and abrasion resistance, solvent resistance, wettability, noncytotoxicity, and other features. For the manufacture of protective organic coatings a number of different techniques have been devised and used. A careful selection of polymer, coating process, and manufacturing conditions can result in high-performance coatings with improved attributes when applied correctly. Polymer coatings have recently been shown to be effective and widely used in a variety of applications, including solar cells, batteries, separation techniques, diodes, corrosion defense, packaging, and heathcare applications.
