Influence of silver nanoparticles on the surface characteristics and electrical properties of polypyrrole/PET polymeric composite films for electronic devices‏

The motivation behind this study is to fabricate novel nanocomposite materials with stronger dielectric characteristics to be applied in electronic devices. The chemical oxidative polymerization technique was employed to fabricate the PET/(PPy-Ag) polymer composite films. These films consist of silver nanoparticles (AgNPs) and polypyrrole (PPy), and the blend (PPy-Ag) is then deposited on the polyethylene terephthalate (PET) substrate. The choice of method depends on the desired application, the properties of the polymer and the level of nanoparticle dispersion required. The characterization methods, Fourier-transform-infrared spectroscopy (FTIR) and energy dispersive X-ray (EDX) were utilized in this study. The EDX data show that the PET/(PPy-Ag) is successfully fabricated with elements C, N, O and Ag, with weight ratios of 15.76%, 8.92%, 65.88% and 9.44%, respectively. The influence of (PPy-Ag) on the conductivity and surface wettability of …
