Hardback. Etat : New. As global priorities shift towards sustainable resources, there is a growing interest in alternatives to petroleum-based raw materials for industrial polyurethane (PU) foam production. Polyurethane foams (PUFs), produced from the reaction between a polyol (a polymer with multiple hydroxyl groups) and a diisocyanate, are widely used for their versatility. They range from flexible foams, like those found in mattresses or furniture, to rigid foams used for home insulation. The market for PU foams is anticipated to grow due to rising demand for comfort. Historically, petroleum-based polyols have been favored for their availability and versatility. However, as petroleum supplies dwindle, with oil reserves projected to be exhausted by around 2052, the pressing need for sustainable alternatives is clear to sustain the PU industry. Bio-based substitutes, such as polyols derived from palm, soybean, castor, and sunflower oils, have been extensively researched to replace the petroleum-based polyol feedstock. This book focuses on applying coconut oil-derived polyols in polyurethane foam production, offering a detailed examination of their potential benefits and associated difficulties. The introductory chapter outlines the critical need for greener alternatives and emphasizes the significant role of coconut oil as a substitute for petroleum-based polyols. Subsequent chapters delve into the chemistry and synthesis of coconut oil-derived polyols and polyurethanes, providing insights into their properties and contributions to polyurethane formulations. This book further provides an overview of how coconut oil's high saturation impacts the polyol production process and explores methods to overcome these challenges. It bridges the gap between raw material science and practical applications using coconut oil in polymer studies. It provides valuable information for researchers and industry professionals aiming to innovate with sustainable polymer materials.…

Hardback. Etat : New. This concise book delves into the innovative use of carrageenan in the green synthesis of metal oxide nanoparticle synthesis. It explores this emerging approach's mechanisms, highlighting its benefits over traditional syntheses. The unique properties imparted by carrageenan to metal oxide nanoparticles and how these enhance the material for various applications are also discussed. Furthermore, concerns regarding the scalability of this green synthesis are explored, particularly the challenges faced in large-scale production, reproducibility, economics, and environmental sustainability.Uniquely focuses on the carrageenan-mediated approach to metal oxide nanoparticle synthesisDetails the mechanisms specific to metal oxide nanoparticle synthesis and the relevance of carrageenan in nanoparticle enhancement (through doping)Covers the scalability and reproducibility of this emerging approach to bridge research and industrial productionThis book serves as a primer for researchers and advanced students in materials science, chemistry, and chemical engineering to aid them in connecting their existing knowledge with the related peer-reviewed literature.…
