Biodegradable materials have ascended in importance in recent years and this book comprehensively discusses all facets and applications in 29 chapters making it a one-stop shop.
Biodegradable materials have today become more compulsory because of increased environmental concerns and the growing demand for polymeric and plastic materials. Despite our sincere efforts to recycle used plastic materials, they ultimately tend to enter the oceans, which has led to grave pollution. It is necessary, therefore, to ensure that these wastes do not produce any hazards in the future. This has made an urgency to replace the synthetic material with green material in almost all possible areas of application.
Biodegradable Materials and Their Applications covers a wide range of subjects and approaches, starting with an introduction to biodegradable material applications. Chapters focus on the development of various types of biodegradable materials with their applications in electronics, medicine, packaging, thermoelectric generations, protective equipment, films/coatings, 3D printing, disposable bioplastics, agriculture, and other commercial sectors. In biomedical applications, their use in the advancement of therapeutic devices like temporary implants, tissue engineering, and drug delivery vehicles are summarized.
Audience
Materials scientists, environmental and sustainability engineers, and any other researchers and graduate students associated with biodegradable materials.
