Sustainable biosynthesis of crosslinkers from polysaccharides and fatty acids
A novel method for producing cost-effective, biodegradable crosslinkers using enzyme-enabled synthesis of polysaccharides and epoxidized fatty acids. This approach balances performance with sustainability, offering an eco-friendly alternative to conventional chemistries.
Overview
This innovative solution focuses on the biosynthesis of crosslinkers using polysaccharides and epoxidized highly unsaturated fatty acids. By leveraging enzyme-enabled covalent combination, this method provides a sustainable and cost-effective alternative to traditional crosslinking chemistries, which are often costly or damaging to polysaccharide structures. The resulting crosslinkers offer a balance between performance and biodegradability, positioning them as an eco-friendly option for industries seeking sustainable materials.
