Processing/structure/property relationship of multi‐scaled PCL and PCL–HA composite scaffolds prepared via gas foaming and NaCl reverse templating

In this study, we investigated the processing/structure/property relationship of multi‐scaled porous biodegradable scaffolds prepared by combining the gas foaming and NaCl reverse templating techniques. Poly(ε‐caprolactone) (PCL), hydroxyapatite (HA) nano‐particles and NaCl micro‐particles were melt‐mixed by selecting different compositions and subsequently gas foamed by a pressure‐quench method. The NaCl micro‐particles were finally removed...
