BIOMEDICAL IMPLANTABLE MATERIALS

摘要

The invention relates to the incorporation of bone-growth reactive compounds and anti-infection agents upon the surface of an implantable polymeric material to enhance the biological properties of the resultant multifunctional composite material. To this end, supercritical carbon dioxide was used to plasticise the surface of the polymer and permit the incorporation of bone-bonding compounds and anti-microbial compounds to the structure of the implants. Nanodiamond particles and a Tea Tree Oil- derived compound, terpinen-4-ol, were used to enhance the bone bonding and antimicrobial properties of the implants, respectively.
