Potential Oscillations

Fractal growth patterns of polyaniline were developed during electropolymerization of aniline using the surfactants sodium dodecyl sulphate (NaDS) and NaDS containing cetyl trimethyl ammonium bromide (CTAB). Growth kinetics was studied and electric potential oscillations were monitored as a function of time. On addition of CTAB polymer growth was inhibited due to coordination of CTAB with the growing polyaniline chain. The average particle size of the polymer aggregate obtained from aniline- NaDS-H2O system was ~150 nm as evident by Transmission Electron Microscopy (TEM) results. Polymer aggregates were characterized by electrical conductivity measurements, X-ray diffraction (XRD) and Thermogravimetric (TG) studies. An interaction between NaDS and aniline was observed in the absence of electric field as evident by (i) electrical conductivity of aqueous solution of NaDS in the absence and presence of aniline, and (ii) their crystallization patterns on microslides. A mechanism for the development of fractal patterns and electrical potential oscillations is proposed on the basis of diffusion limited aggregation process.

Polymer Blend Electrolyte

The composite polymer electrolyte consisting of poly (ethylene oxide) (PEO), KI, I2 and TiO2 was blended with low molecular weight poly (ethylene glycol) (PEG) and (PEG-MA)-Ru. The SEM images of these blended PEO electrolytes showed better dispersion of materials and the electrochemical impedance spectroscopic study showed an increase in conductivity compared to that of composite PEO electrolyte. These results were consistent with enhanced efficiency of DSSCs using these blended PEO electrolytes. The energy conversion efficiencies of DSSCs using composite PEO-PEG, PEO-(PEG-MA)-Ru and PEO-PEG-(PEG-MA)-Ru polymer blend electrolytes were 5.47, 5.05 and 5.28, respectively compared to 4.99 of DSSC using composite PEO electrolyte. The long-term storage of unsealed DSSCs at room temperature for 93 days demonstrated that the cell efficiency gradually decreased to 0.49-1.88%. DSSCs assembled with composite polymer blend electrolyte showed a slower decrease than that of DSSC using composite PEO electrolyte. It was found that the composite PEO-PEG-(PEG-MA)-Ru polymer blend electrolyte of 1.0:0.1:0.1 weight ratio gave the best improvement in stability of DSSCs.
