Research Progress on Preparation and Properties of Bio-Based Polyurethanes from Amino Acid and Its Derivatives
As a kind of renewable resource,bio-based raw materials have the characteristics of less pollution and easy recyclability compared to petroleum-based raw materials.The research on polyurethanes synthesized by bio-based feedstocks has been quite extensive,while a wide range of bio-based materials can be chosen.Amino acid as a kind of bio-based raw material,has various structures and high reactivity with easy access to obtain,whose degradation products are non-toxic and harmless.There are versatile methods to synthesize polyurethanes using amino acid as different components.The application of amino acid and its derivates in bio-based polyurethanes synthesis is reviewed;The relationship between structure and performance of the polyurethanes is expounded.The prospect and directions of future development of amino acid and bio-based polyurethanes is envisioned.
