This book presents engineering applications of polymer-based nano-blends. It discusses the recent developments, in the area of engineering applications, and summarizes many of the important polymer-based nano-blends. In particular, it looks into more advanced topics like blends in biomedical applications, biorecognition of anticancer drug daunorubicin application, binders for particle board, packaging applications, thermoplastic starch-based LLDPE films for active packaging, and optical and antibacterial applications.
