The Analysis of Natural Microstructures Resembling Synthetic Phase-Separated Block Copolymers in Soft Biomaterials and Hard Bio-Minerals

Abstract. For humans, we come into contact with a lot of different materials every day. Many products or medical treatment equipment are made by soft biomaterial, hard bio-minerals and synthetic phase-separated block copolymers. This paper, through a method of literature review, explores the similarity of microstructures and explains the reason why they have similar structures. The paper finds that some synthetic phase-separated blocks have some similar properties to soft biomaterials, and hard biominerals. For example, the CS-g-PCL copolymer is biocompatible, biodegradable, and exhibits appropriate mechanical behavior. The microstructure of soft biomaterials and hard bio-minerals is very similar to the morphology of synthetic phase-separated block copolymers. This is because they both go through a process of phase separation, which results in the formation of nano- or micro-sized self-assembled structures with specific functions and structures. The paper has many scientific papers, which will be of great help to the future research of these materials.
