Preparation and properties of emulsion electrospinning Sacha inchi oil/polyvinyl alcohol nanofiber membrane

Abstract

Abstract: This paper studies the preparation of nanofibers from Polyvinyl alcohol (PVA)/ Sacha inchi oil emulsion under different spinning conditions and its properties. The conductivity and viscosity of the emulsion were measured and the fiber morphology and structure were observed by SEM and TEM to adjust and optimize the parameters. Thermal analysis and Fourier transform infrared spectroscopy (FTIR) characterization were used to characterize the interactions between the components of the fiber membrane. And the hydrophilic property of the fiber membrane surface was measured by contact angle measuring instrument. Finally, we know that the best ratio of PVA / Sacha inchi oil / Tween 80 is 14:5:1, spinning voltage 25kV, receiving distance 18cm. Under this condition, the fibers with average diameter of 570nm have good morphology and uniform distribution. The results of FTIR and thermal analysis showed that the fiber film successfully encapsulated Sacha inchi oil and showed good thermal decomposition stability under 330℃. The measurement of the contact Angle shows that the surface of the fiber film has good hydrophilic property.
