dc.description.abstract | Aloe Vera gel (AVG), and polyvinyl alcohol (PVA) are compatible materials
with the human tissues. The current research studied the characteristic of nanofiber
membranes made of AVG (aloe Vera filtrate/AVF) and aloe Vera extract (AVE) combined
with PVA with varying AVF concentrations of 10, 20, and 30 wt.%), while
AVE concentrations ranged from 0 to 5 wt.%. Changes in surface morphologies and
tensile properties of the nanofiber membranes due to AVF and AVE concentrations
and the correlation effect between them are the goals of this research. The fiber
diameter and tensile strength of AVF/PVA membranes increased with AVF concentration.
The AVF/PVA membrane with 30 wt.% AVF showed the highest tensile
strength (3.58 MPa) and 233 nm in fiber diameter. The addition of 1% AVE concentration,
significantly improved the tensile strength and modulus of AVE/AVF/PVA
membrane: i.e., 8.78 MPa and 26.8 MPa, respectively, with a smaller fiber diameter
around 124 nm. At AVE concentration higher than 1%, the tensile properties
gradually decreased, and fiber diameter increased. As a result, the properties of the
AVE/AVF/PVA membranes could be the candidate material for wound dressing due
to their comparable properties to that of natural skin. | en_US |
