Abstract To synergistically improve the mechanical properties and osteogenic activity of electrospinning poly( l -lactide) (PLLA) membrane, chitosan (CS) nanofibers were firstly introduced to prepare sub-micro and nanofibers interpenetrated PLLA/CS membrane, which was further surface modified with a polydopamine (PDA) layer to obtain PLLA/CS-PDA. Surface morphology, porosity, surface area and hydrophilicity of the obtained fibrous membranes were studied in detail. As compared to pure PLLA, the s...

Abstract In this study, icariin (ICA), one of the main active ingredients of Herba Epimedii for osteogenesis, was applied to functionalize electrospinning poly( l -lactide) (PLLA) fibrous membrane via an intermediate layer of polydopamine (PDA) to obtain enhanced cytocompatibility and osteogenic activity. For this purpose, an array of PDA-coated PLLA fibrous membranes (PLLA-0.5PDA, PLLA-1PDA, PLLA-2PDA, PLLA-5PDA) and ICA-modified PLLA-2PDA fibrous membranes (PLLA-2PDA-10ICA, PLLA-2PDA-20ICA, PL...

To improve both the mechanical properties and cytocompatibility of poly(l-lactide) (PLLA), rod-like chitin whiskers (CHWs) were prepared, and subsequently surface modified with l-lactide to obtain grafted CHWs (g-CHWs). Then, CHWs and g-CHWs were further introduced into PLLA matrix to fabricate CHWs/PLLA and g-CHWs/PLLA nanofiber membranes by electrospinning technique. Morphologies and properties of the CHWs and g-CHWs were characterized. The surface-grafted PLLA chains played an important role ...

Abstract Rod-like chitin whiskers (CHWs) were prepared by acid hydrolysis and then surface-modified with l -lactide to obtain grafted CHWs ( g -CHWs). The structures, morphologies and properties of the CHWs and g -CHWs were studied by FTIR, solid state 13 C NMR, TG, XRD, FESEM and TEM. Subsequently, CHWs and g -CHWs were used as reinforcing agents for a poly( l -lactide) (PLLA) matrix to fabricate CHW/PLLA and g -CHW/PLLA nanocomposites via solution casting. The resulting nanocomposites were ful...
