Conducting polyaniline/silver nanoparticles (PANI-Ag) nanocomposite was synthesized by in-situ polymerization of aniline in the presence silver nitrate as precursor. Nanocomposite characterized UV-VIS, PL, XRD, FTIR, SEM and TGA to study effect embedded into PANI on morphology, structure, crystalline thermal stability conducting polyaniline. The optical studies show that absorption edge PANI-Ag exhibits significant blue shift. photoluminescence emission peak shifted towards when compared...
Nowadays, the increased emission of hazardous volatile organic compounds (VOCs) due to rapid growth in manufacturing industry has enforced demand for highly sensitive, selective, and stable gas sensors. Among different types sensors, we resolved issues associated with chemoresistive alcohol sensors like low selectivity, temperature instability, long-term instability using iodine-doped polyvinyl acetate (IPVAc) films. These polymer-based will be beneficial power consumption, ease manufacture,...
Herein, aqueous ammonium sensing characteristics of polyvinylpyrrolidone (PVP) capped silver nanoparticles (Ag-NPs) coated optical fiber-based sensors are presented. The PVP-capped Ag-NPs were prepared using cold and modified polyol synthesis methods. Aqueous detection was carried out by the surface plasmon resonance (SPR) effect observed in fiber system. methods on performance studied. cladding with according to standard protocol for investigation. probe response analyzed varying...
Industrialization has led to an increasing need for specific and selective gas sensors in the past few decades. Environmental monitoring of certain volatile compounds such as ammonia is necessary. Advancements food storage sector have created cheap effective amine chemosensors. Classical chemosensors still face several issues, a lack selectivity low sensitivity toward amines. Sensitivity defined relative change response expressed percentage. In this work, we resolved issues associated with...
We are introducing 4′-aminodibenzo-18-crown-6 ether (A2BC) modification of gold nanoparticles coated optical fiber as a new sensor for evanescent wave trapping on the polymer to detect low-level potassium ions. characterized these by X-ray Diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR), Nanoparticle tracking analysis (NTA), Field Emission scanning electron microscopes (FE-SEM), and UV–Visible spectroscopy. In present study, we modified with A2BC selective sensing (K+) The...
Volatile organic compounds (VOCs) are majorly used in the manufacturing industry and hazardous to sustainability of environment. Polymeric sensors, rather than more traditional metal oxide currently taking lead attention greater part VOC sensing investigations. In polymeric plasma polymerized thiophene (PPTh) films being investigated because their unique properties, wasteless fabrication, feasibility for commercial mass manufacturing. present study, we fabricated PPTh powered by a 13.6 MHz...
The successful deployment of sodium-ion batteries (SIBs) requires high-performance sustainable and cost-effective anode materials having a high current density. In this regard, sodium disulphide (NiS2) has been prepared as composite with activated carbon (C) using facile hydrothermal synthesis route in the past. X-ray diffraction pattern as-prepared NiS2/C material shows well-defined peaks NiS2. Most carbonaceous are amorphous, Brunauer-Emmett-Teller (BET) study that surface area is close to...
In the present investigation, we demonstrated fabrication of polyethylene glycol (PEG) embedded a WO 3 -graphene film.Transparent and electrically composite films were fabricated on ITO coated substrate by incorporation Nano sheets into PEG followed spin coating chemical reduction.The obtained film exhibited good sensitivity for H 2 LPG gas sensing applications to be used in diverse areas.
The LPG gas sensing response of polyethylene oxide ( PEO )- Cu = 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8, 0.9 and 1.0 wt. %) composite thick films prepared on alumina substrates by using novel screen printing technique are reported in present paper. responses were tested at 1000 ppm home-built static system [between room temperature - 50 °C]. A very high value SF 1400 was obtained an optimum 47 °C for a film with 0.7 wt.%. Further, better response, 700 low operating 36 0.2 %. the found...
