Poly(ε-caplactone) (PCL), widely used in sutures, implants, tissue engineering scaffolds, suffers drawbacks of low softening temperature and poor mechanical properties. In order to address this problem, PCL was processed with α-cyclodextrin to form an inclusion complex and then stripped the host α-cyclodextrin away to yield bulk PCL resulted in largely extended chains, called coalesced PCL. PCL/coalesced PCL single-component fibers fabricated by electrospinning process showed enhanced crystallize and mechanical properties. Here we report the relationships between physical properties and multilength scale of ordered level of PCL/coalesced PCL single-component fibers by thermal analysis, X-Ray, and neutron scatterings.
