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.
