“…Moreover, the crystallinity of the hybrid materials increased with the incorporation of Pt particles into the structure, due not only to the pi-pi interactions of PANI and rGO but also to the interaction between the PANI chains and Pt nanoparticles. [41][42][43][44] Additionally, Pt_rGO/PANI:PSS hybrid materials with different Pt amounts showed increasing crystallinity with increasing amount of Pt particles in the structure, owing to the enhanced interaction between PANI and Pt (Fig. S2 †).…”

With recent developments in technology, tremendous effort has been devoted to producing materials for flexible device systems. As a promising approach, solution-processed conducting polymers (CPs) have been extensively studied owing to their facile synthesis, high electrical conductivity, and various morphologies with diverse substrates. Here, we report the demonstration of platinum decorated reduced graphene oxide intercalated polyanililne:poly(4-styrenesulfonate) (Pt_rGO/PANI:PSS) hybrid paste for flexible electric devices. First, platinum decorated reduced graphene oxide (Pt_rGO) was fabricated through the chemical reduction of platinum cations and subsequent heat reduction of GO sheets. Then, the Pt_rGO was mixed with PANI:PSS solution dispersed in diethylene glycol (DEG) using sonication to form a hybrid PANI-based paste (Pt_rGO/PANI:PSS). The Pt_rGO/PANI:PSS was printed as a micropattern and exhibited high electrical conductivity (245.3 S cm(-1)) with flexible stability. Moreover, it was used in a dipole tag antenna application, where it displayed 0.15 GHz bandwidth and high transmitted power efficiency (99.6%).

“…Then mesoporous layer of TiO 2 was cast with doctor blade method on the dense blocking layer by spreading a TiO 2 Paste which was prepared according the reported procedure. 36 The film was burned again at 450 0 c for 30 mints and cool down to room temperature. The prepared TiO2 anode was subsequently dipped in 0.5 mM solution of N719 dyefor 24h at room temperature to afford the sufficient dye adsorption.…”

This paper demonstrates the facile synthesis of high performance silver-polypyrrole-multiwall carbon nanotubes (Ag-PPy-FMWCNTS) nanocomposites via electrodeposition method on stainless steel substrate and its application as a low cost counter electrode (CE) for the precious platinum (Pt) free DSSC. The nanocomposites were characterized by variety of techniques such as Fourier transforms infrared (FTIR), X-ray diffraction, Scanning electron microscope (SEM), cyclic voltammetry (CV) and Four probe technique respectively. The cyclic voltammetry and Tafel polymerization measurements of Ag-PPy-FMWCNTS nanocomposites CE reveal the favorable electrocatalytic activity and low charge transfer resistance Rct(2.50 Ω cm2) for I3−/I− redox solution. The four probe studies showed the large electrical conductivity (226S cm−1) of Ag-PPy-FMWCNTS nanocomposite. The DSSC assembled with Ag-PPy-FMWCNTS nanocomposites CE display the considerable short circuit current density (13.95 mA cm−2) and acceptable solar to electrical conversion efficiency of 7.6%, which is higher to the efficiency of DSSC with thermally decomposed Pt reference electrode 7.1%. The excellent conversion efficiency, rapid charge transfer in combination with low cost and simple fabrication method of Ag-PPy-FMWCNTS nanocomposites can be exploited as an efficient and potential candidate to replace the Pt CE for large scale production of DSSC.

“…[6][7][8][9] However, it is difficult to meet the requirements in all industries with PANI alone. Up to now, many PANI-based composites such as PANI/Ag, 10,11 PANI/Au 12 and PANI/Zn 13,14 have shown great performance. Therefore, the development of PANI-based composites is of great significance.…”

Polyaniline (PANI)/Ce 3+ and PANI/Ce 4+ composites were successfully prepared by in situ polymerization in an aqueous solution of poly(2-acrylamido-2-methylpropane sulfonic acid) and characterized by Fourier transform infrared spectroscopy, ultraviolet-visible spectroscopy, X-ray photoelectron spectroscopy, SEM, TEM and electrochemical methods. The results showed that the PANI/Ce ion composites had a high degree of sphericity, high electrical conductivity and good electrochemical performance. The conductivity of PANI/Ce(NO 3 ) 3 reaches a maximum of 46.76 S cm −1 at 20 wt% of Ce(NO 3 ) 3 . It is increased by 377% by comparison with that of pure PANI. In particular, the polarization results showed that the corrosion current density (0.47 A cm −2 ) and the inhibition efficiency (97%) of PANI/Ce(NO 3 ) 3 were better than the results for PANI and PANI/Ce(SO 4 ) 2 composite. This suggested that the PANI/Ce(NO 3 ) 3 composite has promising applications in conductive materials, anticorrosion coatings and other related fields.
