Description

technical field [0001] The invention relates to the field of biological material preparation, in particular to a preparation method of ceramic-based core-shell fibers. Background technique [0002] Bioactive ceramic materials are used in bone tissue engineering as an artificial replacement for bone. Because of their specific biological and physiological functions, they are widely favored by researchers and clinicians. Bioactive ceramics are usually used as bone repair materials in the form of ceramic blocks, granules, powders or bone cement. In contrast, ceramic fibers can provide a A more ideal bone microenvironment can achieve better bone repair effect. Ceramic fibers are more and more widely used in the field of bone repair. The preparation methods of ceramic fibers can include template-assisted synthesis, self-assembly, electrospinning, etc., among which electrospinning is the most common fiber manufacturing technology at present, which can prepare continuous and direct...
