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

To improve the dispersion and interfacial interaction between halloysite nanotubes (HNTs) and poly(l-lactide) (PLLA) matrix, and hence to increase the mechanical properties and cytocompatibility of the HNTs/PLLA composite, a facile approach was developed to prepare polydopamine-coated HNTs (D-HNTs) by the self-polymerization of dopamine (DOPA), and then HNTs and D-HNTs were further introduced into PLLA matrix to fabricate HNTs/PLLA and...
