Recrystallization improves the mechanical properties of sintered electrospun polycaprolactone

In contrast with the current state-of-the-art which assumes that tissue engineering scaffolds only grow weaker following exposure, in these scaffolds maximum values of compressive strength and modulus were observed after 7 d of aqueous immersion. This suggests that polymeric recrystallization can be used to increase or optimize mechanical properties in vitro/in vivo. Scaffolds that increase their mechanical integrity during biological exposures constitute a new pathway enabling clinical advances.
