The replacement of polyols synthesized from petrochemical by polyols originating from natural products, notably from vegetable oils and animal fats, has been the subject of research projects for a number of decades. Very recently, however, the polymers industry has intensified its efforts to include the “green products”, such as biobased polyols, in applications already available in the market. Examples of such applications include polyurethane foams, elastomers and epoxides. This book describes the extraction of the natural constituents of several fruits and plants as well as their chemical conversion to polyols. In addition to the chemistry involved in the process, particular emphasis is attributed to their applications.

Polyurethanes are formed by reacting a polyol (an alcohol with more than two reactive hydroxyl groups per molecule) with a diisocyanate or a polymeric isocyanate in the presence of suitable catalysts and additives. Because a variety of diisocyanates and a wide range of polyols can be used to produce polyurethane, a broad spectrum of materials can be produced to meet the needs of specific applications. During World War II, a widespread use of polyurethanes was first seen, when they were used as a replacement for rubber, which at that time was expensive and hard to obtain. During the war, other applications were developed, largely involving coatings of different kinds, from airplane finishes to resistant clothing. Subsequent decades saw many further developments and today we are surrounded by polyurethane applications in every aspect of our everyday lives. While polyurethane is a product that most people are not overly familiar with, as it is generally "hidden" behind covers or surfaces made of other materials, it would be hard to imagine life without polyurethanes.

Rethinking Polyester Polyurethanes: Algae Based Renewable, Sustainable, Biodegradable and Recyclable Materials explains how and why bio-based materials, specifically algae, will change the polymer industry. The book provides background on algae, polyurethanes (PUs), and their everyday use. It covers the biology and chemistry behind how and why these materials are engineered to be both biodegradable and, through the process of depolymerization, fully recyclable. Chapters cover Re-evaluating the Sources, Redefining the Analytics, Reformulating Polyester Polyurethanes, and The Future. The latter part of the book describes the landscape of bio-based materials, the eco-consumer, and insights into the industry problem of “greenwashing. This book is a valuable resource for industry professionals who use polyurethanes in the supply chain for manufactured products, those in sales and marketing or regulatory roles who wish to better understand the unique advantages of bio-based materials, and researchers studying R&D of biobased polyurethanes or remediation of microplastics pollution on land and in bodies of fresh and saltwater worldwide. Builds on the foundation of sustainable, renewable, biodegradable, recyclable microplastics, with lifecycle assessment, techno-economic analysis, and the green premium Clarifies the true economics—if we were to go back to initial development of the plastics industry, what would we do differently? Covers the basic science—the knowledge required to effectively communicate the use of materials that are on first examination more expensive, but on closer examination less expensive when environmental consequences are factored

Polyurethane nanocomposites present an attractive and sustainable way for designing smart materials that can be used in packaging, health and energy applications. Biobased Smart Polyurethane Nanocomposites brings together the most recent research in the field from the basic concepts through to their applications. Special emphasis is given to sustainable biodegradable polyurethane nanocomposites with hyperbranched architecture. The book introduces biobased polyurethanes and the nanomaterials that can be used as nanocomposites followed by the resulting polyurethane nanocomposites. The second part then explores important applications in paints and surface coatings, shape memory, self-healing, self-cleaning, biomaterials and packaging materials. Written by a leading expert on polyurethane nanocomposites, the book is a great introduction to this smart material and its applications.

This edited book compiles all category viewpoints in waterborne polyurethanes (WPUs) dispersions, composites, characterizing techniques, and allied applications such as coatings, adhesives, sealants, anticorrosive, flame-retardant, and biomedical applications. The book brings together panels of highly accomplished experts in the field of advanced polymers for versatile applications. It encompasses basic studies and addresses topics of novel issues which cover all the aspects in one place. The book is an invaluable guide to newcomers, research scholars, professors, and R&D industrial experts working in the field of polyurethane chemistry. Polyurethanes are excellent materials in coating technology owing to their chemical resistance, toughness, abrasion resistance, and mechanical stability. However, polyurethane dispersion contains volatile organic compounds (VOCs) and hazardous air pollutants (HAPs) which are harmful to the environment. Hence, green chemistry research focuses on discovery of waterborne polyurethanes (WPUs) and pay attention. WPUs have fascinated growing interest in wide range of industrial and commercial applications.
