Nanocomposites comprising biocompatible polymer matrices and inorganic nanoparticle fillers represent a new group of biomaterials for tissue engineering scaffolds and biomedical implants and devices. It has been demonstrated that addition of ceramic nanoparticles to polymer matrices greatly influences mechanical, physical and biological properties. The key to good performance is to achieve good homogeneity of the nanoparticle dispersion and uniform microstructure. Thus, these systems require controlled formulation methods (melt/solution processing, improved mixing). Much of the research to date has focused on homopolymer/nanofiller composites, while block or multiblock copolymers/nanofillers have not been yet extensively studied. Multiblock poly(aliphatic/aromatic-ester)s (PEDT) represent novel and interesting biocompatible materials offering the processability of thermoplastics combined with the good elasticity of rubber (thermoplastic elastomers, TPE). It is expected that incorporation of biocompatible ceramic phases (e.g. TiO2 nanoparticles) may be effective in increasing bioactivity as well as cell adhesion and growth for use of the composites in tissue engineering and other biomedical applications.
