| Summary: | Filtration is an effective
method in any process concerning the removal of potential infective substances
via a size separation mechanism. The filter can be made from various materials.
This research analyzes the fabrication of nanofiltration membranes made from
polyvinyl alcohol (PVA) nanofibers reinforced with ramie cellulose nanocrystal
(CNC) using the electrospinning method. The physical and mechanical properties
of the filters were investigated with varying CNC concentrations in PVA to
investigate the effect of the CNC content. The results showed that the fiber
diameter in the membranes was not significantly related to the CNC content.
However, the strength and elongation increased with an increase in CNC
concentration until a certain value was reached, at which point it started
decreasing. The SEM image showed that the membrane nanofibers have a pore size
small enough to be used in a nanofiltration process. SEM-EDX and TGA/DSC
testing were also carried out to determine the elements in the membrane and
show the suitability of the thermal resistance. |
