“…Compared to PVK, nanocomposite coatings exhibited improved micro hardness which is attributed to the incorporation of Al 2 O 3 nanoparticles. With the increase in wt % of Al 2 O 3 nanoparticles in a certain volume fraction, Al 2 O 3 nanoparticles are much closer to each other compared to microparticles in the polymer matrix, and hence, nanoparticles will resist more strongly the penetration of the indentation in the matrix . This results in the increase in micro hardness for nanocomposites than that of polymer at a constant volume fraction of Al 2 O 3 particles.…”

Poly(vinylcarbazole) (PVK) and PVK-alumina (Al 2 O 3 ) nanocomposite coatings were electrochemically coated on 316 L stainless steel (SS) substrates for corrosion protection of 316 L SS in 3.5 weight (wt) % NaCl medium. The formation of PVK and incorporation of nanoalumina particles in PVK-Al 2 O 3 nanocomposite coatings were confirmed from attenuated total reflectanceinfrared spectroscopy (ATR-IR). Thermal analysis (TG) results showed enhanced thermal stability for the composites relative to PVK. Incorporation of Al 2 O 3 nanoparticles enhanced the micro hardness of PVK coated 316 L SS. The dispersion of alumina nanoparticles was examined via scanning electron microscope (SEM) and tunneling electron microscopy (TEM) and revealed distinct features. The influence of nanoparticles on the barrier properties of PVK and PVK-Al 2 O 3 nanocomposites was evaluated in aqueous 3.5 wt % NaCl by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) studies. The results proved that PVK nanocomposite coatings provided better protection for 316 L SS than PVK coatings. The drastic increase in impedance values is due to the high corrosion resistance offered by the PVK nanocomposite coatings that arises due to the interaction between Al 2 O 3 nanoparticles and PVK. The highest corrosion protection shown by the 2 wt % nano Al 2 O 3 incorporated PVK composite coatings proved enhanced corrosion resistance compared to PVK.

“…The conductivity of the polymer-composite membrane compared with that of the pure liquid electrolytes -EC/DEC/NaClO 4 (1M) with sodium ion conductivity of σ Na = 6.4 × 10 −3 S cm −1 and EC/DEC/LiClO 4 (1M) with lithium-ion conductivity of σ Li = 6.2 × 10 −3 S cm −1 at 25 • C -is consistent with the dominance of PVP on the ionic conductivity of the membrane. [20][21][22][23] The polymer composite with 45 wt% of PVDF-HFP, 25 wt% of PVP, and 30 wt% of Sb 2 O 3 is found to retain high flexibility, remarkable mechanical strength, and good conductivity. The data provided hereafter are for the pristine polymer and a polymer composite with a PVDF-HFP/PVP ratio of approximately 1.8.…”

We describe here preparation and performance of an ultra-flexible and low-cost Sb 2 O 3 /polymer composite membrane separator for Na-ion or Li-ion batteries operating with metallic Na or Li anodes. The separator has a large electrolyte window, excellent thermal and mechanical stabilities when infused with EC/DEC/AClO 4 (1M) electrolyte (A = Li or Na), excellent wettability and acceptable ionic conductivity to 1C rate. The ability of the separator to block anode dendrites from crossing it is demonstrated in symmetric alkali-metal cells and in the performances of Na-ion and Li-ion cells with/without loading with Sb 2 O 3 .

Nitrate is one of the nutrients that can give an effect on the environment if it is applied in excess. It is also easily soluble in water and it has the potential to be a pollutant in groundwater by the over-process of fertilizer. Therefore, it needs a detected component to give the right measure for nitrate in the soil, called a nitrate ion sensor. It consists of three electrodes configuration, namely, working, counter, and reference electrodes with conductive polyaniline doped with Nitrate (NO₃‾) which is fabricated by thick film technology. In previous research, acidic media was used as a solvent for polyaniline, while this research used water (H2O) solvent. The result of characterization showed that particles were distributed evenly on the sample with the form of particles being small balls with a dimension of 0.18 µm and the percentage of atomic elements being: 91.96 % carbon, 3.14 % nitrogen, and 4.9 % oxygen. The performance of sensors was investigated using potentiostat with four concentrations of nitrate standard solution. The result showed good response with a voltage range in each concentration of nitrate standard solution being 0.5002 Volt (10 mg/l), 1.3552 Volt (20 mg/l), 1.1208 Volt (50 mg/l), and 0.8963 Volt (100 mg/l). It was found that nitrate sensors with nitrate-doped conductive polymer, polyaniline, as the sensitive membrane responded well to detecting nitrate elements in precision farming and the sensitivity showed that for every 1 mg/l concentration in nitrate standard solution, the voltage increases by 0.0007.
