Preparation and Characterization of Electrical, Morphological and Topographic Properties for Advanced Conductive PMMA/PVDF/PANI Ternary Blend for Low Percolation Threshold Devices
Ali Hussein, Asra1.
The presented work targets on developing an advanced conductive polymer blend. This polymer hasa low permeation threshold at low concentrations of conductive polymer.Two groups of polymer blend, consist of amixture of polyvinylidene fluoride (PVDF), polymethylmethacrylate(PMMA) and polyanylene (PAni) were used.Thefirst group was used with various weight fractions (1%, 3% and 5%) of Pani, whilesecond group(10%, 30%, and50%)of PVDFwas used via solution casting method. The tests carried out were the AFM,FTIR, SEMas well as analysis ofelectrical conductivity. The results show that the dielectric constant was observed to saturate at mid frequency of 103Hz–105Hz. At low frequency (101Hz), Cp, dielectric constant and impedance resistance werehigh. Moreover, it could be observed that the Cp, dielectricconstant and impedance resistance value for optimized samples was decreased for group PMMA-30%PVDF-5%PAnimore than PMMA-50%PVDF-5%PAni. TheAFM results demonstrate the topographic of neat PMMA where bigger globules can be seen. Littleamounts of these globules were noticed inthe ternary blend of PMMA-PVDF–PAni.AFM micrographof ternaryblend demonstratesthat the expansion of PVDF wt.% in the blend reducesstraightened globules. In the second group, the ternary blends were smoother than neat PMMA.The FTIR investigationdemonstratesthe higher absorptivity peak because of C -O aggregate showsup in the ternary blend. Aslight move of the crest at 1727 from 1730cm−1for neat PMMA might be owing to the good homogeneity ofPMMA matrix with PAni and PVDF in the ternary blend. Morphological propertiesrepresented by SEM imageillustrateshomogenous mixing forboth groups.In PMMA-50%PVDF-5%PAniblend, the zone involved by PAnihas been restrictedwhich results in a lower permeation threshold of PAni, and an expansion in the conductivity of the sampleas compared with counterpart groupPMMA-30%PVDF-5%PAni.
