This book presents a broad overview of various aspects of electropolymerization. Lately, special attention has been paid to polymer thin films. These films play a crucial role in many technical functions, including coatings, adhesives and organic electronic equipment like sensors and detectors. Electrochemical polymerization is preferred in such scenarios, particularly if the polymeric compound is meant to be used for thin films, since electrogeneration facilitates close control over the thickness of the film, a critical criterion for creation of devices. Additionally, it has been illustrated that the material properties can be adjusted using parameter control of the electrodeposition procedure. Electrochemistry is an exceptional means, not just for creation, but also for classification and use of diverse kinds of resources. This book brings forth an opportune summary of the present state of data pertaining to the use of electropolymerization for preparation of new materials, including conducting polymers and diverse potential of functions.
