Nano-PLLA/chitosan scaffolds were prepared through thermally induced phase separation(TIPS). With incorporation of chitosan fibers, composites not only improved the mechanical properties of nano scaffolds, but also reduced the degradation rate of mechanical properties which deepen the applications of scaffolds better.

In this study, a nanofibrous poly (L-lactic acid) (PLLA) scaffold reinforced by Hydroxyapatite (HAP) and β-tricalcium phosphate (β-TCP) was fabricated using the thermally induced phase separation method. The composite scaffold morphology showed a nanofibrous PLLA matrix and evenly distributed β-TCP/HAP particles. The composite scaffold had interconnective micropores and the pore size ranged 2-10 μm. Introducing β-TCP/HAP particles into PLLA matrix significantly improved the mechanical properties of the composite scaffold. In summary, the new composite scaffolds show a great deal promise for use in bone tissue engineering.
