This study is devoted to studying the properties of a new polymer sorbent based on polyvinyl alcohol and carboxymethylcellulose using infrared spectroscopy and thermogravimetric analysis. The influence of calcium chloride on the performance characteristics of the sorbent, such as oil capacity, floatation, moisture content and polymer degradation, is studied. The cross-linked matrix has improved properties: increasing the oil capacity and flotation time, retention of the structure when the sorbent is on the water s...

Fabrication of nanofibers is a field of research attracting a lot of interest from technologici scientists because of its great applications in many fields. In order to design the polymer drug delivery system, we had to select a polymer that is biocompatible, biodegradable, non-toxic and approved for medical use. One of the polymers that fulfill those requirements is poly (vinyl alcohol) (PVA). There have been various reports on the fabrication of PVA nanofibers with solvents as water, or water with different salt...
