三维孔道结构的HA@Ag@ZIF-8@BG可降解支架的制备及性能OA
Preparation and Performance of HA@Ag@ZIF-8@BG Degradable Scaffolds with Three-dimensional Pore Structure
采用 3D打印技术制备了生物活性玻璃(BG)支架,并通过 1150℃烧结得到了纯BG支架.以金属有机框架(ZIF-8)、硝酸银、透明质酸(HA)为原料,采用原位生长和双溶剂的方法成功制备了不同组分的HA@Ag@ZIF-8@BG支架.利用Zeta、BET、XRD、FT-IR和SEM对材料的微观结构和性能进行了研究,探究了各组分支架的孔隙率、抗压强度以及降解能力.结果表明:原位生长未改变BG支架的原有三维孔道结构和孔隙率;支架的抗压强度仍处于人体松质…查看全部>>
Bioactive glass(BG)scaffolds were prepared by 3D printing technology,and pure BG scaffolds were obtained by sintering at 1150℃.HA@Ag@ZIF-8@BG scaffolds with different components were successfully prepared using metal organic framework(ZIF-8),silver nitrate,and hyaluronic acid(HA)as raw materials by in situ growth and dual-solvent method.The microstructure and properties of the materials were investigated using Zeta,BET,XRD,FT-IR and SEM.The porosity,compress…查看全部>>
