Advances in Physicochemical Properties of Biopolymers (Part 1) Editor(s): Martin Masuelli and Denis Renard DOI: 10.2174/97816810845341170101 eISBN: 978-1-68108-453-4, 2017 ISBN: 978-1-68108-454-1 Recommend this Book to your Library Biopolymers have some problems (e.g., fragmentation, loss of mechanical properties, degradation) to substitute fully petrol-based polymers. The results showed that although xanthan gum biopolymer has limited effects on nominal flexural strength and fracture toughness at high water contents, it increases clay fracture energy and final displacement at zero external load in all water contents. Biomaterials made from proteins, polysaccharides, and synthetic biopolymers are preferred but lack the mechanical properties and stability in aqueous environments necessary for medical applications. For several years, biopolymers combined with other components are regularly determined to have good mechanical properties, thermal stability, as well as proper physicochemical and morphological properties, and the physical properties of biopolymers widely vary for different biopolymer types and compositions, which play an important role on the application of biopolymers.
