Preparation process of novel porous biphase calcium phosphate ceramic scaffold
The invention relates to the technical field of ceramic scaffolds, in particular to a preparation process of a novel porous biphase calcium phosphate ceramic scaffold, which comprises the following steps: by component limitation, taking BCP precursor powder as a raw material, hydrogen peroxide as a foaming agent, sodium carboxymethyl cellulose as a rheological agent and lauryl sodium sulfate as a dispersing agent; the calcium phosphate ceramic with high porosity and good pore connectivity is prepared under the condition that a template is not used; the preparation method comprises the following steps: carrying out modification treatment on BCP precursor powder, carrying out in-situ growth of nano zinc oxide on the BCP precursor powder by adopting a microwave hydrothermal method, grafting a styrene-maleic anhydride polymer with a coupling function, and then grafting linear polyether amine to obtain the modified BCP precursor powder, so that various properties of the ceramic bracket are greatly improved.
本发明涉及陶瓷支架技术领域，具体是一种新型多孔双相磷酸钙陶瓷支架的制备工艺，通过成分限定，以BCP前体粉末为原料，以双氧水为发泡剂，以羧甲基纤维素钠为流变剂，以十二烷基硫酸钠为分散剂，在未使用模板的情况下制备孔隙率高、孔隙贯通性好的磷酸钙陶瓷；对BCP前体粉末进行改性处理，采用微波水热法在BCP前体粉末上原位生长纳米氧化锌，接枝具有偶联功能的苯乙烯‑马来酸酐聚合物，然后接枝线性聚醚胺，得到改性BCP前体粉末，大幅提高陶瓷支架的各项性能。
