Abstract

Background: Nanofiber membrane/non-woven composite material is composed of electrospinning nanofiber membrane and non-woven fabric, which combines the supporting role of nonwoven material and the special nano-size effect of nanomaterials.

Objective: These composite material can be widely used in biomedical, filtration and other related fields. In the actual use process, nanofiber membrane/non-woven composite material is often subjected to external forces such as puncture or bursting. As a result, the mechanical study of nanofiber membrane/ non-woven composite materials has a high value and practical significance.

Methods: The nanofiber membrane/non-woven composite material was obtained by spraying solution (different concentrations of titanium dioxide-loaded Poly (vinyl alcohol) (PVA)) on meltblown polyester non-woven fabric. The surface morphology and fiber diameter of different concentrations nanotitanium dioxide-loaded Poly (vinyl alcohol) fiber were investigated by Field Emission Scanning Electron Microscopy (FESEM). The surface distribution of TiO2 on the electrospun fibrous membranes was characterized by Energy Disperse Spectroscopy (EDS). The semi-blunt puncture behavior of different concentrations of nano-titanium dioxide-loaded nanofiber membrane/non-woven composite material was conducted by universal material machine.

Results: With the increase of concentrations of nano-titanium dioxide particles, the surface smoothness of nanofibers diminishes, the unevenness of the diameter distribution of the fiber increased and the maximum semi-blunt puncture strength increased.

Conclusion: The addition of hard particles does contribute to improving the puncture properties of the composite materials. Several patents, related to electrospinning and bubble electrospinning equipment for nanofiber fabrication, have been reported.

Keywords: Electrospinning, nano-titanium dioxide, PVA, semi-blunt puncture behavior, composite material, patents.
