Abstract
In this work, the EVOH/Ti(3)C(2) composite fibers were prepared via electrospinning and the effect of added Ti(3)C(2) on 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/Ti(3)C(2) composite fibers were studied. The Ti(3)C(2) is uniformly loaded onto the surface and inside the composite fiber and affects the fiber diameters. Furthermore, The Ti(3)C(2) self-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/Ti(3)C(2) fibrous membranes. With the increase in the Ti(3)C(2) concentration in the electrospinning polymer solution, the addition of Ti(3)C(2) not 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 Ti(3)C(2) composite fibers, and also expand the application of electrospun EVOH and EVOH/Ti(3)C(2) fibrous membranes.
