The physical properties and response of osteoblasts to solution cast films of PLGA doped polycaprolactone.

Polycaprolactone films doped with poly(lactide-co-glycolide) (65:35) in 0, 10, 20, and 30 (wt%) were prepared and evaluated in terms of morphology, dynamic contact angle analysis, and thermal properties. The unique surface morphology of the doped PCL film resulted, without introducing significant microstructure disruption of PCL aggregation. The doped PCL film registered a lower contact angle and increased hydrophilicity. Osteoblast cells attached to all doped materials, the 10% and 20% doped materials demonstrating the greatest cell growth.
