Solubility and diffusivity of CO2 in poly(l-lactide)-hydroxyapatite and poly(d,l-lactide-co-glycolide)-hydroxyapatite composite biomaterials

▶ Solubility and diffusivity of supercritical CO2 in polymers and composite materials. ▶ The effect of filler concentration on the solubility and diffusivity. ▶ PLLA-HA composites: presence of filler decreases CO2 solubility and diffusivity. ▶ PLGA-HA composites: small filler content favors CO2 solubility and diffusivity.
