Preparation and Study of Properties of Porous Bone Renovating Material of Modified-MWNTs/Nano-HA/PLA
|Keywords||Nano - hydroxyapatite Modified multi- wall carbon nanotubes Polylactic acid Situ composite performance Porous Degradation|
Research and development of materials for human hard tissue repair is a topic of global concern and is a very active area in the study of biological materials . Bone repair material demand increases with the human trauma, inflammation , tumors and congenital malformations and other reasons , the study of bone repair material has the gradual deepening of the development of ways to become more diverse . Successfully fabricated nano - hydroxyapatite particles , and Modification of MWNTs / nano HA composites as the core content , using gas-phase oxidation and liquid-phase oxidation prepared with the carboxyl group of multi- wall carbon nanotubes (MWNTs - COOH). Ultrasonic assisted by in situ synthesis of nano-hydroxyapatite (nano-HA) coated MWNTs-COOH composite nanomaterials (MWNTs - COO / nano -HA ) and successful preparation of a modified MWNTs -COO / nano-HA/PLA porous bone repair materials . Its mechanical properties , hydrophilic properties , and degradation properties were investigated .
