Abstract EN

Nanolayered particulate of Zn-based layered double hydroxide (LDH) was prepared by a low temperature greener sol-gel method.

X-ray diffraction (XRD) studies were performed on the particles annealed at different temperatures.

Hexagonal crystal structure of the as-grown LDH particulates was observed.

The crystal structure was modified to tetragonal structure of layered double oxide (LDO) on annealing at 250°C.

Rietveld fittings showed a collapse of interlayer separation distance along the preferred orientation of the LDH particles as a result of heat treatment.

Further, LDH particles were used as fillers of electrospun poly(vinyl alcohol) (PVA) fibers.

Heat treatment of the polymer fibers was also performed at different temperatures, and thermal changes were studied by thermogravimetric analysis (TGA), Raman spectroscopy, and scanning electron microscopy (SEM) techniques.

Improved interaction of fibers with LDH nanoparticles was observed and ascribed to LDH-related LDO phase transformation at higher temperature.

Thermal mechanisms of the rapid weight loss in filled fibers were discussed in comparison to the pure PVA fiber losses.

Experimental Raman frequencies of the composite fibers were compared with the calculated Raman modes of the enol and ZnO monomers.

The molecular vibration frequencies were found to differ significantly due to heat treatment.

Finally, the role filler in the faster and greener thermal decomposition of polymeric fibers was also discussed in the present work.
