“…The grafting with PVDF chains was designed using the 3-HT monomer, leading to the filling of the nanochannel cylinder with the conducting P3HT polymer, followed by the sulfonation of the exclusively grafted films to make the nanochannels better ion conductors. The grafting followed by sulfonation led to the appearance of peaks at δ = 2.80 and 1.95 ppm for the grafting of P3HT on PVDF chains, at δ = 7.90 ppm for the grafting sulfonation in P3-HT chains, and at δ = 8.2, 7.7, 7.2, and 5.6 ppm for the sulfonate protons, as shown in the NMR spectra in Figure a. − The grafting and sulfonation were also confirmed through FTIR measurements by the appearance of peak positions at 1649 and 1730 cm –1 due to the corresponding −CC– and −CS symmetrical stretching vibrations of the thiophene aromatic ring attached to the PVDF chain (Figure b). , The sulfonation in the grafted nanochannel was visualized through the peak positions at 1047 and 989 cm –1 due to the SO 2 and SO 3 – vibration peaks attached to the PVDF chain, respectively . Similar results are also verified through UV–visible spectra.…”

The current review article provides deep insight into the fluoropolymers and their applications in energy technology, especially in the field of energy harvesting and the development of fuel cell electrolyte polymeric membranes. Fluoropolymers have gained wide attention in the field of energy applications due to their versatile properties. The incorporation of nanofillers within the fluoropolymer to develop the nanohybrid results in an enhancement in the properties, like thermal, mechanical, gas permeation, different fuel cross-over phenomena through the membrane, hydrophilic/hydrophobic nature, ion transport, and piezo-electric properties for fabricating energy devices. The properties of nanohybrid materials/membranes are influenced by several factors, such as type of filler, their size, amount of filler, level of dispersion, surface acidity, shape, and formation of networking within the polymer matrix. Fluoropolymer-based nanohybrids have replaced several commercial materials due to their chemical inertness, better efficacy, and durability. The addition of certain electroactive fillers in the polymer matrix enhances the polar phase, which enhances the applicability of the hybrid for fuel cell and energy-harvesting applications. Poly(vinylidene fluoride) is one of the remarkable fluoropolymers in the field of energy applications such as fuel cell and piezoelectric energy harvesting. In the present review, a detailed discussion of the different kinds of nanofillers and their role in energy harvesting and fuel cell electrolyte membranes is projected.

“…Considering the surface roughness values reported in the literature, it can be clearly stated that root-mean-square (RMS) of (PAH/ PAA50-PSS50) was significantly higher than that of Caruso' work [32]. It was reported that (PAA/PAH) 8 (assembled at pH 3.5/7.5, respectively) yielded a surface morphology with relatively high RMS value (23 nm) by blending PAA with PSS. They were also reported that the surface roughness can be systematically decreased by rising PSS content in the blend.…”

“…Today, new TFC membranes can be prepared from organic and inorganic materials using different modern technologies [7]. The physical and chemical properties of TFC membranes can be tuned for many applications, including fuel cells [8,9], gas [10][11][12], and liquid [13] separation/purification and various water treatment processes [7,[14][15][16]. For this purpose, the upper thin layer and the nonselective porous support can be optimized separately.…”

Our study is concerned with the development of a novel type of layer-by-layer (LbL) self-assembled membrane from a single cationic polyelectrolyte (PE) and blended anionic PEs. Their synthetic seawater stability is investigated as a function of PE type and blend ratios using quartz crystal microbalance-dissipation (QCM-D). These materials adsorbed into multilayers with significant viscoelasticity. Poly(allylamine hydrochloride) (PAH) and poly(vinylamine hydrochloride) (PVA) based LbL blend films did not show any multilayer decomposition with the addition of synthetic seawater regardless of blend ratio while chitosan based multilayers disintegrated. The flux of PVA based blend membrane to water with 1,000 ppm NaCl was found to be 6.7 L/ m 2 .h at 40 bar and the flux properties of the membranes were highly dependent on both the thickness and hydrophilicity of multilayers. Ion rejection can be controlled with the charge of the top layer consistent with a Donnan exclusion approach. Sodium ion rejection of 60.5 layered LbL blend membrane was 98.4% at 40 bar and it was determined that sodium ion rejection improved 110.7% compared to a commercial nanofiltration membrane. POLYM.

“…Combination of polymer matrix with different kinds of organic and inorganic fillers leads to improved properties of resulting composite. These materials are of great scientific and technological interest and are used in various applications like aerospace and automotive structures, or marine and sports goods, to name a few [1][2][3][4][5][6]. Polypropylene (PP) belongs to the group of the thermoplastic polymers offering excellent mechanical properties and electrical and chemical resistance against higher temperatures.…”

Electrically conductive polypropylene/graphite (PP/graphite) composites were prepared via blending granulated PP with maleic anhydride grafted PP and natural graphite. Electrical conductivity of prepared samples containing either 65, 70, or 75 wt.% of graphite was measured and the most conductive sample containing 75 wt.% of graphite was exposed to UV irradiation for 1 and 24 hours or thermally treated at 170 °C for 1 hour. The influence of thermal and UV exposure on the structural and electrical changes in such treated samples was studied. Local current measurements on the surface were made using scanning spreading resistance microscopy and morphology of the surface was studied by atomic force microscopy. X-ray diffraction analysis, infrared and Raman spectroscopy were also used for the structural characterization. Properties of treated and untreated samples are compared and differences are discussed.
