AbstractMulti-walled carbon nanotube (MWCNT)/dendrimer sheet scaffolds, i.e., dendrimers attached to the surface of MWCNT buckypaper, were fabricated, and a hydroxyapatite (HAp) coating prepared on dendrimer-modified buckypaper using an alternate soaking process (ASP) is described. The amount of the HAp that is retained on the surface of the MWCNT/dendrimer sheet scaffolds depends on the modification method; i.e., surface modification performed after the formation of the buckypaper is much more effective in producing MWCNT/HAp hybrid materials than surface modification prior to the formation of the buckypaper. Moreover, biomimetic crystallization of calcium phosphate on buckypaper in simulated body fluid (SBF) was carried out. TEM analysis of the resulting MWCNT/dendrimer sheet scaffolds revealed that the MWCNT backbone was covered with scaly crystals.Multi-walled carbon nanotube (MWCNT)/dendrimer sheet scaffolds, i.e., dendrimers attached to the surface of MWCNT buckypaper, were fabricated, and a hydroxyapatite (HAp) coating prepared on dendrimer-modified buckypaper using an alternate soaking process (ASP) is described.

树枝状聚合物改性巴克纸上的磷灰石涂层和多壁碳纳米管上纳米磷灰石的形成

摘要制备了多壁碳纳米管 (MWCNT)/树枝状聚合物片状支架,即附着在 MWCNT 巴基纸表面的树枝状聚合物,并描述了使用交替浸泡工艺 (ASP) 在树枝状聚合物改性的巴基纸上制备的羟基磷灰石 (HAp) 涂层. 保留在 MWCNT/树枝状聚合物片状支架表面的 HAp 量取决于改性方法;即,在巴基纸形成之后进行的表面改性在生产 MWCNT/HAp 混合材料方面比在巴基纸形成之前进行表面改性更有效。此外,在模拟体液(SBF)中进行了巴克纸上磷酸钙的仿生结晶。所得多壁碳纳米管/树枝状聚合物片状支架的 TEM 分析表明,多壁碳纳米管骨架被鳞状晶体覆盖。 制造了多壁碳纳米管 (MWCNT)/树枝状聚合物片状支架,即附着在多壁碳纳米管巴克纸表面的树枝状聚合物,并且描述了使用交替浸泡工艺 (ASP) 在树枝状聚合物改性巴基纸上制备的羟基磷灰石 (HAp) 涂层。保留在 MWCNT/树枝状聚合物片状支架表面的 HAp 量取决于树枝状聚合物的含量。此外,在模拟体液(SBF)中进行了巴克纸上磷酸钙的仿生结晶。所得 MWCNT/树枝状聚合物片状支架的 TEM 分析表明,MWCNT 主链上覆盖着鳞片状晶体。制备附着在 MWCNT 巴基纸表面的树枝状聚合物,并描述了使用交替浸泡工艺 (ASP) 在树枝状聚合物改性的巴基纸上制备的羟基磷灰石 (HAp) 涂层。保留在 MWCNT/树枝状聚合物片状支架表面的 HAp 量取决于树枝状聚合物的含量。此外,在模拟体液(SBF)中进行了巴克纸上磷酸钙的仿生结晶。所得 MWCNT/树枝状聚合物片状支架的 TEM 分析表明,MWCNT 主链上覆盖着鳞片状晶体。制备附着在 MWCNT 巴基纸表面的树枝状聚合物,并描述了使用交替浸泡工艺 (ASP) 在树枝状聚合物改性的巴基纸上制备的羟基磷灰石 (HAp) 涂层。保留在 MWCNT/树枝状聚合物片状支架表面的 HAp 量取决于树枝状聚合物的含量。此外,在模拟体液(SBF)中进行了巴克纸上磷酸钙的仿生结晶。所得 MWCNT/树枝状聚合物片状支架的 TEM 分析表明,MWCNT 主链上覆盖着鳞片状晶体。保留在 MWCNT/树枝状聚合物片状支架表面的 HAp 量取决于树枝状聚合物的含量。此外,在模拟体液(SBF)中进行了巴克纸上磷酸钙的仿生结晶。所得 MWCNT/树枝状聚合物片状支架的 TEM 分析表明,MWCNT 主链上覆盖着鳞片状晶体。保留在 MWCNT/树枝状聚合物片状支架表面的 HAp 量取决于树枝状聚合物的含量。此外,在模拟体液(SBF)中进行了巴克纸上磷酸钙的仿生结晶。所得 MWCNT/树枝状聚合物片状支架的 TEM 分析表明,MWCNT 主链上覆盖着鳞片状晶体。
