Abstract

Electrical conductivity of polymers may be increased with the addition of conductive fillers as minor phases. We prepared nanocomposite films through the addition of lithium hexafluorophosphate (LiF6P), an alkali metal salt, and gold nanoparticles (AuNPs), as minor phase materials into poly (methyl methacrylate) (PMMA). Though an improved conductivity of the PMMA film specimen with LiF6P was observed, it did not occur with AuNPs. PMMA/LiF 6P and PMMA/AuNPs solutions were prepared separately in different ratios to achieve 0.20, 0.50, 0.75 and 1.00 wt % of LiF6P in PMMA and 0.2 wt% of AuNPs in PMMA. Electrical conductivity was measured on nanocomposite samples with the mentioned contents of LiF6P and AuNPs. The nanocomposite films with LiF6P show improved electrical conductivity, and the sample with 0.75 wt% LiF6P has the highest conductivity value with an improvement of three orders of magnitude compared to that of the pure PMMA film. However, the film sample with only AuNPs did not show any obvious change in its electrical conductivity. The mechanism of the conductivity improvement was examined by FTIR analysis.
