Improvement of mechanical and biological properties of porous CaSiO3 scaffolds by poly(d,l-lactic acid) modification

Porous calcium silicates (CaSiO3, WT) are regarded as a potential bioactive material for bone tissue engineering. However, their insufficient mechanical strength and high dissolution (degradation) limit their biological applications. The aim of this study is to surface modify WT scaffolds with poly(d,l-lactic acid) (PDLLA) to improve their mechanical and biological properties. The phase composition, microstructure, porosity and interconnectivity...
