| Abstract: | Poly(lactide-co-glycolide)(PLGA)/silk fibroin(SF) blend nanofibrous porous membrane was fabricated by electrospinning of PLGA/SF blend solutions dissolved in 1,1,1,3,3,3-hexafluoro-2-propanol(HFIP).The morphology,molecule structure, mechanical and hydrophilic properties of PLGA/SF blend membrane were investigated by field emission scanning electron microscope(FE-SEM),Fourier transform infrared spectrum(FT-IR),multi-purpose tensile tester and drop shape analyzer. The results show that the fiber diameter decreases and the uniformity tends to be better with the increase of SF.There are miscibility and hydrogen bond between PLGA and SF molecules.The mechanical characterization of blend fibrous membrane becomes very poor when the content of SF is more than 40%.Nevertheless hydrophilic property of blend fibrous membrane is improved markedly due to the adding of SF. |
