Inorganic particles such as HAP, TCP, SiO2 or TiO2 are dispersed in solutions of polymers, for example in PLA, PCL or hydrogels. Various dispersion processes are available (ultrasonic, ball mill) for this purpose. Subsequently these dispersions are processed e.g. by wet-spinning, electrospinning, knife coating or extrusion and are consolidated in this process. Crosslinking is possible by means of the functionalization of the internal interfaces of the composite materials. In this way the tensile strength of hydroxylapatite, for example, can be increased by dispersion in polylactic acid.
