Highly flexible and stretchable sensors are becoming increasingly widespread due to their versatile applicability in human/robot monitoring sensors. Conductive polymeric composites have been regarded as potential candidates for such sensors, carbon nanotubes (CNTs) widely used fabricate composites. In the present study, CNT-embedded high were fabricated using a facile three-roll milling method, which mitigates drawbacks of conventional fabrication methods. CNTs content varied between 0.5 4.0...
The syntheses, characterization, and crystal structures of the reaction products Cu2+ with imidazole (Himz) different aromatic carboxylates, viz.: [Cu(Himz)2(cinn)2(H2O)] (1), [Cu(Himz)2(paba)2] (2) [Cu(Himz)2(clba)2] (3) (cinn– = C9H7O2–, paba– C7H6NO2–, clba– C7H4ClO2–) are described studied by spectroscopic (UV–visible, FTIR) measurements. Single-crystal X-ray diffraction analyses indicate that each complex is monomeric. metal ion in 1 adopts square-pyramidal coordination geometry arising...
The present study introduces a modified approach to synthesize polyaniline (PANI) and polypyrrole (PPy) doped with graphene oxide (GO) or (GN) through an in situ emulsion polymerization (EP) technique. Dodecyl benzene sulfonic acid (DBSA) was used as surfactant doping agent well during the reaction. morphology microstructure of synthesized polymers their nanocomposites were studied by scanning electron microscopy, transmission Fourier transform infrared spectroscopy, X‐ray photoelectron...
ABSTRACT The present study demonstrates a modified in situ emulsion polymerization (EP) approach convenient for the formation of polypyrrole/graphene (PPy/GN) nanocomposites with harnessed conductivities. A series PPy/GN were prepared by loading different weight percent (wt %) GN during EP pyrrole monomer. was carried out presence dodecyl benzene sulfonic acid, which acts as an emulsifier and protonating agent. microstructures studied scanning electron microscopy, transmission X‐ray...
We have synthesized unique flexible pressure‐sensitive nanocomposites by means of a solution mixing method, adding multiwalled carbon nanotubes (MWCNTs) into thermoplastic urethane (TPU) matrix along with poly(methyl methacrylate) (PMMA) microbeads various sizes. The influence the PMMA bead sizes on pressure sensing properties was studied over range pressures. were used to achieve an early percolation threshold at low loadings MWCNTs. scanning electron microscopy study nanocomposites'...
A coordination polymer, [Cu(tmen)(succ)]n·4nH2O (1) (where succ2- = succinate dianion, tmen N,N,N′,N′-tetramethylethylenediamine), was prepared by reacting CuCl2·2H2O, succinic acid (H2succin) and tmen, characterized elemental analysis, UV-visible spectroscopy, FTIR thermogravimetric (TGA) single-crystal X-ray diffraction analyses. The copper(II) ion in 1 has a distorted cis-CuN2O4 octahedral environment which the metal is bonded to chelating molecule four O atoms from two bridging,...

In this model, we used a 50 WP photovoltaic panel to produce electrical energy. This electricity production was directly and stored in battery. design, coupled batteries hydrogen as means of storing case overcharging the battery, it will be attached with water electrolysis convert excess amount chemical energy battery into storage. Hydrogen compacted gas We PEM (proton exchange membrane) technologies breakdown molecules oxygen, which were then designed tanks. Different supply voltages our...
