This study aims to prepare a novel porous titanium (Ti) scaffold in order to improve the biocompatibility of the metallic implants. Porous Ti was produced by a Liquid foaming method and subsequent chemical treatments. It was found that the scaffold had three-dimensionally hierarchical porous structures with pore size ranging from nanometer to micrometer scale, and it also had activated surface. Mechanical test results showed that the scaffold also has sufficient compressive strength to meet the requirements of implantation. Protein adsorption results indicated that the novel scaffolds significantly enhanced the protein adsorption.
本研究旨在制备一种新型多孔钛（Ti）支架，以提高金属植入物的生物相容性。通过液体发泡法和后续的化学处理制备多孔 Ti。研究发现，该支架具有从纳米到微米级的三维分级多孔结构，并且具有活化表面。力学性能测试结果表明，该支架还具有足够的抗压强度，满足植入要求。蛋白质吸附结果表明，新型支架显著增强了蛋白质吸附。
