| 摘 要： | Biopolymers have more and more important relations with human life.The research on biopolymers involves such fields as chemistry,biology and medicine.In term of source,the biopolymers comprise natural biopolymers and synthetic biopolymers.The development of synthetic biopolymers,especially biodegradable polymers,has enriched the structure,properties and varieties of biopolymers,promoted their applications in many areas such as sutures,bone fixation parts,temporary supporting tubes,drug controlled release carriers and tissue engineering scaffolds.
