Preparation and Characterization of Electrospun EVOH/Ti3C2 Composite Fibers
In this work, the EVOH/Ti3C2composite fibers were prepared via electrospinning and the effect of added Ti3C2on the structure and properties of electrospun EVOH fibrous membranes was further investigated. The morphology, crystal structure, thermal properties, wettability, tensile properties, as well as air permeability and water vapor permeability of as-prepared EVOH/Ti3C2composite fibers were studied. The Ti3C2is uniformly loaded onto the surface and inside the composite fiber and affects the fiber diameters. Furthermore, The Ti3C2self-orients along the fiber axis and does not change the crystal structure of the electrospun EVOH fibers, improving the crystallinity and thermal stability of the electrospun EVOH/Ti3C2fibrous membranes. With the increase in the Ti3C2concentration in the electrospinning polymer solution, the addition of Ti3C2not only rapidly improves the wettability of the fibrous membranes, but also enhances their air permeability, compared with the pristine electrospun EVOH fibrous membranes. The experimental results provide theoretical guidance for the preparation of Ti3C2composite fibers, and also expand the application of electrospun EVOH and EVOH/Ti3C2fibrous membranes.
