Over the course of fifteen selected chapters, this book explores the production, chemistry, and applications of waterborne polyurethanes (WBPUs). The first chapter is a conceptual introduction to WBPUs, and the following eight chapters cover different kinds of waterborne polyurethanes, such as those made with natural and synthetic polymers, polyurethane/acrylic hybrids, waterborne polyurethane nanocomposites, and even light stimuli responsive and conductive WBPUs. The remaining six chapters cover various applications of WBPUs ranging from textile treatment and food packing to biomedical applications such as drug delivery.
