Efficient nano-filler for the phase transformation in polyvinylidene fluoride nanocomposites by using nanoparticles of stannous sulfate
Abstract
Abstract Nanocomposites of PVDF-tin sulphate were synthesized by solution-mixing technique with 0–4% w/w loadings of SnSO4 nanoparticles. The novel nanoparticles of SnSO4 were synthesized via in situ deposition method and its surface modification was performed by nonionic polymeric surfactant PEG. XRD analysis revealed that the average diameter of synthesized nanoparticles was 45 nm. Polymeric films of PVDF/SnSO4 nanocomposites were characterized by FTIR, SEM, EDS, TG/DTA, DSC and UV–vis spectrum. FTIR absorption bands show that α and β-phases coexist in pure PVDF which was supported by the 2θ value of XRD at 20.75°. This critical data shows that the phase of PVDF was completely transformed from α to β with incorporation of SnSO4 nanoparticles. The UV absorbance intensity was increased, T g and T d were decreased with the increase in nanoparticles loadings in polymer matrix. The prepared nanocomposites could be used as a smart material for sensing device.
