Abstract
Nano-sized Ni(OH)
2
is being widely as an for various applications like battery, supercapacitor, fuel cell, sensor, catalyze etc. due
to its natural abundance, environmentally friendly and excellent electrochemical property. And these properties of nickel
hydroxide majorly depend on synthesis method. β-Ni(OH)
2
and Modified-β-Ni(OH)
2
(ethylenediamine as templating agent) was
successfully synthesized by conventional chemical precipitation method. β-Ni(OH)
2
and Polyvinyl alcohol (PVA) nanocomposite
formed by vigorous sonication up to the formation of the uniform dispersion. Developed materials were characterized by using
X-ray Diffraction (XRD), Scanning electron microscope (SEM) and Fourier Transform Infrared Spectroscopy (FTIR). Structural
characterization suggested the formation of the hexagonal structure of β-Ni(OH)
2
and particle size was found 7.5 nm and 3 nm
for conventional and modified β-Ni(OH)
2
respectively. Flame retardancy and thermal stability study were exhibited with UL-94
and TG/DTA and it was found that as particle size decreases uniform dispersion and better flame retardancy and thermal
stability.

1. Introduction
Development in nanosheet synthesis and characterization continues unstoppable the nanomaterials make a
revolution in material science. Properties of nanomaterials are better than conventional material example high
surface area to volume ratio.
