▎ 摘　　要

Poly (lactic-co-glycolic acid) (PLGA) and graphene (G) were selected as raw materials to prepare PLGA/G composite nanofiber membranes with different contents by electrospinning using N -N dimethylfor-mamide (DMF) and trichloromethane (TCM) as solvent. Different samples were characterized by scan-ning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), mechanical measurement and photothermal analysis. Results demonstrated that graphene was physical scattered in the PLGA polymer matrix. The crystallization and mechanical tensile behaviors of PLGA/G composite nanofiber membranes were improved with graphene content. In addition, PLGA/G composite nanofiber membranes exhibited a rapid and steady photothermal conversion ability. It is anticipated that the proposed PLGA/G composite nanofiber membrane might be applied as a favorable tumor treatment candidate. (c) 2022 Elsevier B.V. All rights reserved.
