Polycaprolactone is a nontoxic and controllable synthesis of the molecular weight of polymer materials

while has good biocompatibility

different polymer compatibility and biodegradability advantages. Therefore

polycaprolactone is widely used in biomedical

industrial and daily life. With the continuous development of precision medicine concept and modern manufacturing technology

polycaprolactone is manufactured into a variety of structures to achieve controlled drug release

in order to improve the effectiveness of drugs in disease treatment and reduce its side effects. In this study

the research progress of polycaprolactone on microspheres

fibers

micelles and hydrogels drug carriers are reviewed based on the preparation technology

the advantages and disadvantages of different carrier preparation methods have been analyzed

and the future development direction of polycaprolactone as drug carrier material is prospected. The purpose of this study is to provide some references for the research of polycaprolactone controlled release carriers.
