Abstract: Studies on polycaprolactone-based biocomposites in recent years have been listed. Those materials which were adopted to modify polycaprolactone include starch, polylactide, protein, chitosan, cellulose, and so on. The morphology of composite indicated the inefficiency of interfacial adhesion between polycaprolactone and those hydrophilic polymers. The incorporation of compatibilizer or grafting reaction could increase the interaction of blends and improve the mechanical properties of biocom-posites. These different processes and technologies applied in preparing polycaprolactone-based biocomposites also have been compared.

Key words: polycaprolactone, biocomposite, biodegradable
