Abstract
To obtain the different types of technical utilities, the surface of various systems needs to be modified by altering surface properties using polymer coating(s) which is one of the emerging technologies to impart smart functions. The polymer coating has a wide application in various fields such as biomedicals, pharmaceuticals, packaging, corrosion control, electronics, and abrasion control. The coating can be done using both biodegradable and non-degradable polymers having eminent properties such as better mechanical strength, anti-wear characteristics, corrosion protection, electrical conductivity, biocompatibility, and high surface functionality. Several methods have been reported for the fabrication of defensive coatings. A thoughtful selection of polymers, coating methods, and critical process parameters may bring forth a better protective coating with advanced properties. This review discusses the objectives of the polymer coating, various coating technologies, and their smart applications.
Keywords: Biocompatibility, polymers, smart functions, coating, biomedical, pharmaceutical.
