Abstract: Highly porous poly( L lactic acid)/apatite composites were prepared through in situ formation of carbonated apatite onto poly( L lactic acid) foams in a simulated body fluid. The highly porous polymer foams (up to 95% porosity) were prepared from polymer solution by solid–liquid phase separation and subsequent sublimation of the solvent.
