AI Technical Summary
In the manufacture of biodegradable synthetic polymer-ceramic composites, the polymer matrix has problems such as excessive hydrolysis and degradation speed, poor mechanical properties, and inconvenient solvent use during processing, resulting in the implant losing its mechanical properties before bone healing or triggering an inflammatory response.
Composite biomaterials are manufactured by compacting and sintering methods. By compacting biocompatible absorbable organic polymers and bioactive inorganic material powder at low temperatures, and then sintering at low temperatures, forming a tightly bound solid, avoiding polymer melting and solvent use at high temperatures, ensuring the stability and mechanical properties of the polymer matrix.
It improves the mechanical properties and stability of composite biological materials, reduces hydrolysis and degradation, simplifies the manufacturing process, reduces the use of solvents, and is suitable for orthopedic implants, avoids inflammatory reactions and mechanical performance losses caused by degradation.
