| Popis: | In this study, we have successfully prepared polylactide (PLA)/Graphene (G)/multiwalled carbon nanotubes (MWCNTs) solution by a solution-blending technique, and the different composition proportion of PLA/G/MWCNTs composite nanofiber membranes were produced via an electrospinning technique. The morphology, dispersion of graphene/MWCNTs, crystal structure and thermal stability of PLA/G/MWCNTs membranes were studied by SEM, TEM, XRD and TG, respectively. The results showed that the MWCNTs and graphene could disperse randomly into the fibers, and the introduction of graphene and MWCNTs did not mainly affect the crystal structure of PLA. TG test indicated that the addition of MWCNTs and graphene enhanced the thermal stability of the composites. Additionally, the presence of the graphene and MWCNTs in the PLA matrix had an obvious delaying effect on the degradation of PLA, which made PLA/G/MWCNTs nanofiber membrane have large potential in tissues scaffold. |
