Structural and Optical Properties of Li: PVP & Ag: PVP Polymer Films
نویسندگان
چکیده
PVP polymers containing Li or Ag Ions have been synthesized in good stability and transparency by using the solution casting method. Their structural, optical, thermal and electrical properties have been investigated from the measurement of XRD, FTIR, SEM, EDAX, optical absorption spectra, TG-DTA profiles and impedance spectral features in order to evaluate their potentialities for their use in electrochemical display device applications.

Optical properties of Ag nanoparticle-polymer composite film based on two-dimensional Au nanoparticle array film
The nanocomposite polyvinyl pyrrolidone (PVP) films containing Ag nanoparticles and Rhodamine 6G are prepared on the two-dimensional distinctive continuous ultrathin gold nanofilms. We investigate the optical properties and the fluorescence properties of silver nanoparticles-PVP polymer composite films influenced by Ag nanoparticles and Au nanoparticles. Absorption spectral analysis suggests th...
متن کاملEffect of Fe3+–MMT on thermal degradation and mechanical behavior of PVP/Amylose nanocomposite films
Novel nanocomposite films based on amylose (AM) and Fe3+-montmorillonite (Fe3+–MMT) in the matrix of poly (vinyl pyrrolidone) (PVP) were fabricated by using a solution casting method. The X-Ray diffractional analysis indicated that an ion-exchange process occurred between Fe3+–MMT and PVP. Thermogravimetrical analysis (TGA), differential termogravivetrical analy...
متن کاملA Simple and High Yield Solvothermal Synthesis of Uniform Silver Nanowires with Controllable Diameters
Silver nanowires were synthesized by solvothermal method through reducing silver nitrate (AgNO3) with ethylene glycol (EG) in the presence of polyvinylpyrrolidone (PVP). In order to prevent the agglomeration of Ag+ in the initial Ag seeds formation, sodium chloride (NaCl) was added into the solution to form AgCl colloids. By dissolving AgCl in the late stages, Ag+ ions were released into the so...
متن کاملSynthesis and Characterization of Ag/PVP Nanocomposites by Reduction Method
A polyvinylpyrrolidone (PVP)/Ag nanocomposite was prepared by reduction of silver nitrate in ethylene-glycol in the presence of a polymeric protective agent (i.e., poly (N-vinylpyrrolidone)). The size dependent color variation of this nanocolloid is a clear indication of the presence of Ag as nanoparticles in the polymer matrix. The nonlinear optical properties were studied by Z-scan technique ...
متن کاملMechanical, Rheological and Computational Study of PVP/PANI with Additives
Polyvinylpyrrolidone/polyaniline emeraldine salt (PVP/PANI) with additives (TiO2, ZnO, NaCl, and Na2SO4) was synthesized via oxidative in situ polymerization. Because of using PVP/PANI as a protective membrane layer and its applications in an electrical device, we investigated the mechanical and rheological properties of PVP/PANI and other composites in orde...
