Preparation and Characteristics of Electrospun Silver-Containing PHBV Ultrafine Fiber

摘要

The effects of synthesized silver nanoparticles on electrospun PHBV ultrafine fibers were studied by scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and thermal gravimetric analysis (TGA). Addition of silver nanoparticles increased from 0.1% to 2.0%, the sooth ultrafine fiber with an average diameter of about 2 μm formed a non-woven mat was obtained. DSC showed the efficient heterogeneous nucleation by the silver nanoparticles for facilitating PHBV crystallization. The thermal stability of the PHBV/Ag ultrafine fibers improved with the increase in the content of the silver nanoparticles.
