“…Ternary Ni-based oxides or nanocomposites containing Li-Al [64], Li-Zr [65], and Li-W [66] have given particularly interesting results. Finally we note that work has been reported also for number of hybrid materials of NiO-Q, where Q stands for poly(3,4-ethylenedioxythiophene) [67], polypyrrole [68], polyaniline [42], graphene oxide [69], and LiPON [70].…”

Porous nickel oxide films were deposited onto unheated indium tin oxide coated glass substrates by reactive dc magnetron sputtering. These films had a cubic NiO structure.Electrochromic properties were evaluated in 1 M potassium hydroxide (KOH) and in 1 M lithium perchlorate in propylene carbonate (Li-PC). Large optical modulation was obtained for ~500-nm-thick films both in KOH and in Li-PC (~70 % and ~50 % at 550 nm, respectively). In KOH, tensile and compressive stress, due to expansion and contraction of the lattice, were found for films in their bleached and colored state, respectively. In Li-PC, compressive stress was seen both in colored and bleached films. Durability tests with voltage sweeps between -0.5 to 0.65 V vs Ag/AgCl in KOH showed good durability for 10,000 cycles, whereas voltage sweeps between 2.0 to 4.7 V vs Li/Li + in Li-PC yielded significant degradation after 1000 cycles.

“…It was observed that with the addition of NiO in PMOTNiO nanocomposites, the bands coming from PMOT shift to lower wave number due to loss of conjugation and molecular order, in contrast to the bands coming from NiO located at higher wave number. This shift in stretching vibration of Ni-O is due to binding of organic compound to NiO[22]. These results indicate strong chemical interaction between PMOT and NiO nanoparticles 1.…”

Electrically conducting hybrid composites of poly(3-methoxythiophene) (PMOT) and nickel oxide (NiO) (PMOT-NiO) were synthesized by chemical oxidative method with their different proportions. The synthesized PMOT-NiO nanocomposites were characterized for optical, structural, and electrical analysis. Transmission electron microscope (TEM) depicts the morphology of the samples which revealed the transformation of thread morphology of PMOT to the clusters in PMOT-NiO hybrid composites. The structural and optoelectronic properties of hybrid composites were quite different from those of pure PMOT and NiO nanoparticles which were attributed to the chemical interaction between PMOT and NiO nanoparticle. X-ray diffraction (XRD) confirmed the cubic structure of NiO with an average crystallite size of 5 nm. The nanocomposites had lower diffraction peak intensities and smaller interplanar spacing as compared to NiO. Ultraviolet (UV) spectra and fluorescence spectra (PL) showed that the optical behavior of nanocomposites was far superior to PMOT and NiO separately. FTIR spectra revealed that the absorption of PMOT was affected by the presence of NiO nanoparticle. The roomtemperature electrical conductivity was increased up to 4.2× 10 −7 Ω/cm −1 with increase in the concentration of NiO content in PMOT-NiO hybrid composites.

“…Among these materials, polypyrrole (PPy) has been considered as one of the most promising conducting polymers due to its low cost, air stability, environmentally friendly, and easy processing [1][2][3]. However, PPy usually shows a poor thermal and oxidative stability and is difficult to process because of their insolubility in common solvents and infusibility that limits their industrial application [4,5] In order to overcome the shortcomings mentioned above, a series of PPy composites were prepared, such as PPy=SiO 2 [6], PPy=Nano-graphite sheets (NanoGs)=AgCl [7], PPy=MoO 3 [8]. The results showed that the conductivity and mechanical properties of PPy were significantly improved.…”

Nano-graphite sheets (NanoGs) were prepared by treating the expanded graphite with sonication in 95% alcohol solution. The polypyrrole (PPy)/NanoGs/TbCl 3 nanocomposites were successfully prepared by in-situ polymerization. The structure, morphology, and stability of the composites are characterized by transmission electron microscope (TEM), scanning electron microscope (SEM), and thermogravimetric analysis (TG). The PPy/NanoGs/TbCl 3 nanocomposites exhibited much higher electrical conductivity and better thermal property than the pristine PPy. The electrical conductivity of these nanocomposites were adjusted by changing different wt% of the NanoGs and TbCl 3 , the conductivity of the composites was reached 80.0 S/cm with the 7 wt% of TbCl 3 and 3 wt% of NanoGs.
