Microscaled non-woven fabrics with fiber diameters in the range 1.8-3.1 mu m were prepared by electrospinning from a chloroform solution of a degradable multiblock copolymer (PDLCL) consisting of crystallizable poly(omega-pentadecalactone) hard segments (PPDL) and poly(epsilon-caprolactone) switching segments (PCL). The surface morphology and microstructure of the non-woven fabrics were characterized by scanning electron microscopy, temperature-controlled scanning probe microscopy, wide angle X-ray diffraction (WAXD), and small angle X-ray scattering (SAXS). The microstructural analysis demonstrated that the rod-like domains of hard segment (PPDL) formed in the electrospun PDLCL fiber functioned as physical crosslinks. Cyclic, thermomechanical tensile tests showed that the electrospun PDLCL fabrics exhibited good shape-memory properties with strain recovery rates of R-r = 89-95% and strain fixity rates of R-f = 82-83% after the 2nd cycle, when small deformations were applied at clinically relevant temperatures.
