Structure-property relationship of silane-modified polyurethane
A new review focuses on the structure and properties relationship of silane modify PU and the synthesis strategy for modifing PU as per desire application.
Polyurethanes (PUs) belong to a class of engineering materials with a wide range of applications, primarily based on their unique structure-property relationship. Improving the properties and performance of PUs-based materials can be achieved by altering the production process or the raw materials used in their manufacture or via advanced techniques. However, the production of sandwich structure and composite material in one-step processing is a decisive advantage for the specific application.
Synthesis mechanism of silane-terminated PUs
With this motivation, the authors of a new review highlight the recent advances in PUs, the silane-terminated PUs, chemistry, various synthetic routes and shed light on special properties. In detail, they discuss pertinent research studies on the synthesis mechanism of silane-terminated PUs and the influencing state parameters. Besides, they also disclose the relationship between structure of silane modified polyurethanes and its properties. Furthermore, the give information on the crosslinking density, silane concentration and compatibility between organofunctional silane and PUs matrix. Finally, the challenges and urgent issues of further development in this area are discussed.
The review has been published in Progress in Organic Coatings, Volume 176, March 2023.
