Method for Forming Porous Calcium-Phosphate Polymer Composites

Methods for the formation of a porous structure in plastic and thermoplastic calcium-phosphate composites are considered. Plastic compositions were synthesized on the basis of natural polymers (collagen, gelatin and sodium alginate). Biodegradable polymers were used as thermoplastic polymers: polylactide and poly-3-hydroxybutyrate. The approaches to the formation of a porous structure in polymer composites, developed through the use of lyophilic, microwave drying, the use of special devices and gas-releasing additives, the use of 3D printing, and the electroforming of fibers (EPI) indicate the need to combine different methods to achieve a branched porous structure and the required pore sizes in composites.
