Biocompatible and Biodegradable Bioplastics Constructed from Chitin via a “Green” Pathway for Bone Repair

摘要: Biodegradable plastics are urgently needed in the biomedical field to avoid secondary surgery for implants after completing repair of nonload bearing bone defects. Herein, novel chitin based were successfully fabricated by changing shape and aggregation state structure hydrogels through drying under a negative pressure, which led plastic deformation. The prepared using an environmentally friendly aqueous NaOH/urea solvent, then radially oriented pressure form bioplastics (CP) on basis removability molecular bundles hydrogels. Moreover, hydroxyapatite (HAP) was situ synthesized obtain chitin/HAP composite (CHP). Their properties characterized SEM, FTIR, 13C NMR, X-ray diffraction mechanical testing. results indicated that bioplastic preparation “green” physical process, incorporation HAP reinforced significantly t...
