Abstract
Recent years have seen fast development in the field of self-cleaning coatings towards varied applications, such as solar cells, flat display panels, smart cellular phones, building windows, oil pipelines, vehicle coatings and optical devices. The field has been rapidly gaining attention, not only from research and teaching scientists, but also from a growing population of college and graduate students. Self-cleaning coatings describes this interesting field, providing details of natural counterparts with self-cleaning functions, theoretical aspects of self-cleaning phenomena, fabrication strategies and methods, applications and industrial impacts. Edited and written by world-renowned scientists in the field, this book will provide an excellent overview of this field and will be of interest to materials and polymer scientists working in industry and academia.
