  • In situ self-setting mineral-polymer hybrid materials, composition and use thereof
    Patent number: 8389467
    Abstract: The present invention relates to self-setting compositions consisting in admixed liquid and solid components enable the formation of hardened bio-materials having a broad range of properties and performances. The present invention proposes a) a thermo-sensitive self-gelling liquid component, being water-based, comprising at least a polycationic and a phosphate source, wherein the liquid component is a thermo-gelling solution at a pH ranging from 6.5 to 7.4; b) a powder component consisting in at least two calcium phosphate sources. The preferred calcium phosphate source includes apatites, tricalcium phosphates, tetracalcium phosphates and dicalcium phosphates. Both solid and liquid components are admixed to form a flowable slurry that sets in situ into a hardened calcium phosphate based bio-material.
