Area of Science:

  • Biomaterials Science
  • Tissue Engineering
  • Polymer Chemistry

Background:

  • Designing tissue engineering scaffolds with controlled multiscale pore networks is a significant challenge.
  • Biocompatible and biodegradable porous materials are crucial for guiding cell activity and tissue regeneration.

Purpose of the Study:

  • To provide an overview of temperature-driven process technologies for fabricating scaffolds with tailored, interconnected porosity.
  • To develop three-dimensional (3D) porous composite scaffolds with strictly defined pore size distribution.

Main Methods:

  • Fabrication of poly(epsilon-caprolactone) (PCL) scaffolds using thermally induced phase separation (TIPS) and melt co-continuous polymer blending (MCPB).
  • Integration of a salt leaching technique with TIPS and MCPB to achieve bimodal porosity.
  • Characterization of scaffold morphology and mechanical properties for hard tissue regeneration applications.

Main Results:

  • Successful fabrication of 3D porous composite scaffolds with interconnected pore networks.
  • Establishment of bimodal porosity through the combination of polymer blending and salt leaching techniques.
  • Demonstration of potential for tailoring morphological and mechanical properties to mimic extracellular matrix (ECM) of hard tissues.

Conclusions:

  • The developed techniques offer a versatile approach for creating advanced tissue engineering scaffolds.
  • The bimodal porosity and interconnected network are beneficial for cell infiltration and tissue ingrowth.
  • These scaffolds show promise for regenerating hard tissues like bone.
