Mouldable artificial bone composite material and preparation method thereof

A method for preparing a mouldable artificial bone composite material, comprising the steps of:

• adding a catalyst, an initiator, a first monomer, and a second monomer to carry out a thermal reaction to obtain a degradable polymer material, the first monomer being selected from the group consisting of caprolactone and p-dioxanone and the second monomer being selected from the group consisting of lactide or glycolide;
• dissolving the polymer material in an organic solvent to obtain a polymer solution;
• adding and mixing inorganic particles composed of calcium-phosphorus compounds into the polymer solution to obtain a mixture solution;
• and
• drying the mixture solution in a vacuum to obtain the artificial bone composite material composed of the polymer material and the inorganic particles;
• wherein:
• an average molecular weight of the polymer material is 4,000 Da to 16,000 Da;
• the inorganic particles are distributed in the polymer material;
• in a first predetermined temperature range, the artificial bone composite material is in a shape of a mouldable plasticine;
• in a second predetermined temperature range, the polymer material has fluidity;
• the second predetermined temperature is greater than the first predetermined temperature;
• the first predetermined temperature range is 25° C. to 40° C.;
• and
• the second predetermined temperature range is 40° C. to 60° C.
