Enhanced mechanical properties and cytocompatibility of electrospun poly(l-lactide) composite fiber membranes assisted by polydopamine-coated halloysite nanotubes

- D-HNTs was prepared by a facile approach based on the self-polymerization of DOPA.
- The D-HNTs can disperse more uniformly in PLLA matrix than untreated HNTs.
- The interfacial adhesion between D-HNTs and PLLA matrix was obviously improved.
- D-HNTs/PLLA fiber membrane has better tensile properties compared with HNTs/PLLA.
- The D-HNTs/PLLA fiber membrane is favorable to cell adhesion and proliferation.
