The Fabrication and Characterization of PCLRice Husk Derived Bioactive Glass-Ceramic Composite Scaffolds

الملخص EN

The present study was conducted to fabricate a 3D scaffold using polycaprolactone (PCL) and silicate based bioactive glass-ceramic (R-SBgC).

Different concentrations of R-SBgC prepared from rice husk ash (RHA) were combined with PCL to fabricate a composite scaffold using thermally induced phase separation (TIPS) method.

The products were then characterized using SEM and EDX.

The results demonstrated that R-SBgC in PCL matrix produced a bioactive material which has highly porous structure with interconnected porosities.

There appears to be a relationship between the increase in R-SBgC concentration and increased material density and compressive modulus; however, increasing R-SBgC concentration result in reduced scaffold porosity.

In conclusion, it is possible to fabricate a PCL/bioactive glass-ceramic composite from processed rice husk.

Varying the R-SBgC concentrations can control the properties of this material, which is useful in the development of the ideal scaffold intended for use as a bone substitute in nonload bearing sites.
