DESCRIPTION OF THE DATA

The dataset contains data for following measurements:
a) Dielectric Spectroscopy - Room Temperature and Temperature Range (-160 to 160 C)
b) Dynamic Mechanical Analysis
c) Fluroscence Microscopy
d) Fourier Transform Infra-Red Spectroscopy
e) Transmission Electron Miscroscopy
f) X-Ray Diffraction

Methodology:

Transmission electron microscopy (TEM) was conducted using a Hitachi H 7000 TEM operated under high-resolution bright-field mode. To prepare the required samples, a quantity of nanoparticles was 
added to ethanol and sonicated and a small drop of the resulting dispersion placed onto a carbon-coated TEM grid. To determine the particle size distribution present in a given system, multiple TEM images were
obtained from different areas of the above grids, with 40 nanoparticles being chosen at random from these multiple images for analysis using the ImageJ image analysis software package. Attenuated total reflection
Fourier transform infrared (ATR-FTIR) spectra were obtained using an iD7 Nicolet iS5 spectrometer from ThermoFisher. The dielectric response of the samples was measured via broadband dielectric spectroscopy (BDS) using a Solartron 1296 dielectric interface and a Schlumberger SI 1260 impedance/phase gain analyser.
Samples were sputter-coated with 20-mm-diameter gold electrodes prior to analysis and then mounted in a Janis Research STVP 200 XG system for measurement over the temperature range of - 160 to 160 C. 
An AC voltage of 7 V was used from 10^-1 to 10^5 Hz; an integration time of 10 s was used above 1 Hz; below 1 Hz acquired data were averaged over 10 cycles. A Mettler Toledo DMA/SDTA861 was used for dynamic mechanical 
analysis (DMA). It was operated in tension mode with a maximum force of 10 N or 3 lm maximum level with an auto offset of 150%. Measurements were carried out in isothermal steps of 10 C for a temperature range of - 100 C to
160 C and a frequency sweep of 10^–3 to 100 Hz.
