| Résumé : |
Exploring renewable materials to replace petroleum-based building blocks for advanced coatings has been a major thrust area for researchers for the development of eco-friendly and sustainable products. For the last few decades, there has been significant interest among coating researchers around the world to design water-based polyurethane dispersions (PUDs) that can be cured at ambient conditions. Polyurethanes are the most versatile polymers, exhaustive studies have been reported and more details of all aspects of their properties and uses are given. Vegetable oil-based polyurethanes are used in various fields from coatings to elastomers including smart biomaterials. This paper comprises overview in recent developments on the preparation of biobased polyols from plant oils, covering from the general epoxidation as welI as to high light the properties of polyurethanes obtained from them. |
