The synthesis of ternary nanocomposites with tailored properties based on polymer blends is gaining popularity all over the world. Our work introduces a novel ternary nanocomposite of poly (ethylmethacrylate)/polystyrene/silver nanoparticles (PEMA/PS/Ag NPs). Silver nanoparticles were synthesized via laser ablation route at different laser times (5, 10, 15, 20, and 30 min) and scattered in PEMA/PS...... hiện toàn bộ

Concomitant Crystallization of Copper(II) Sachharinato Complexes with 2-methylpyrazine as a Monomer and an One-dimensional Polymer: Syntheses, Crystal Structures, Spectroscopic and Thermal Properties
Springer Science and Business Media LLC - Tập 18 - Trang 407-413 - 2008
Veysel T. Yilmaz, Evrim Senel, Canan Kazak
The reaction of [Cu(sac)2(H2O)4] · 2H2O with 2-methylpyrazine (mpyz) leads two complexes, concomitant crystallization of a mononuclear complex [Cu(sac)2(mpyz)(H2O)2] (1) and a polymeric complex [Cu(sac)2(μ-mpyz)]n (2). Both complexes have been characterized by elemental analyses, magnetic measurements, FT-IR and ESR, TG-DTA and single-crystal X-ray diffraction analyses. Single-crystal X-ray analys...... hiện toàn bộ
Synthesis and Electric Modulus Formalism of Novel Metal-Phthalocyanine Bridged Polymers
Springer Science and Business Media LLC - Tập 24 - Trang 858-864 - 2014
Wael M. Darwish, Mahmoud A. Abd El-Ghaffar, Gamal M. Turky
Novel nickel and copper phthalocyanine polymers, with uniformly carboxylic end groups and carbonyl groups as bridges linking the phthalocyanine units, were successfully prepared. Structural modelling and atomic absorption spectroscopy confirmed the network polymeric structure and suggested at least nine phthalocyanine units in each polymeric network. The dielectric properties of the prepared polym...... hiện toàn bộ
Micro-Nanoarchitectonics of Electroless Cu/Ni Composite Materials Based on Wood
Springer Science and Business Media LLC - Tập 32 - Trang 687-699 - 2021
Yanfei Pan, Qiang Guo, Dingwen Yin, Mayin Dai, Xiaofang Yu, Yinan Hao, Jintian Huang
The changes of properties of wood-based Cu–Ni composites were studied via a simple electroless Cu and Ni method on wood surface to obtain Cu–Ni multilayer composites with excellent properties. The results showed that the wood was conducted via two times electroless Cu and one times electroless Ni had better performance, obtaining good surface roughness (9.99 μm) and good hydrophobic performance (c...... hiện toàn bộ

Physicochemical Analysis of Tetrakis (Thiourea) Palladium Chloride: A Prospective Non Linear Optical Crystal
Springer Science and Business Media LLC - Tập 27 - Trang 739-756 - 2017
N. R. Rajagopalan, P. Krishnamoorthy, K. Jayamoorthy
The solubility test and nucleation kinetics studies of Tetrakis (thiourea) palladium chloride (TTPC) have been carried out and optical quality crystals of TTPC have been harvested by means of slow evaporation method. The single crystal X-ray diffraction studies revealed the orthorhombic structure and Pna21 space group of the crystals. To ascertain the stoichiometry and the purity of the crystals, ...... hiện toàn bộ
Complexation of Tolane by Fluorinated Organomercurials—Structures and Luminescence Properties of an Unusual Class of Supramolecular π-Coordination Polymers

The interaction of the Hg(II) derivatives bis(pentafluoro)phenyl mercury (1), (pentafluoro)phenyl mercury chloride (2) and trimeric perfluoro-ortho-phenylene mercury (3) with tolane (diphenylacetylene) in CH2Cl2 leads to the formation of [1·tolane], [2 2·tolane], and [3·tolane·CH2Cl2]. These adducts have been characterized by elemental analysis, X-ray crystallography, and l...... hiện toàn bộ
Synthesis and Tuning the Structural, Optical and Electrical Behavior of PVA-SiC-BaTiO3 Polymer Nanostructures for Photonics and Electronics Nanodevices
Springer Science and Business Media LLC - - Trang 1-14 - 2023
Majeed Ali Habeeb, Waleed Khalid Kadhim
This study aims to fabricate thick films of polyvinyl alcohol containing (SiC-BaTiO3) nanoparticles in order to improve their structural, optical, and electrical characteristics. The (PVA-SiC-BaTiO3) nanocomposite films are made utilize the casting method. According to optical microscope images, the (SiC-BaTiO3) nanoparticles create a persistent network inside the polymer compared to pure (PVA). F...... hiện toàn bộ
Synthesis and Characterization of Ta-Doped WO3 Nanomaterials for Their Application as an Efficient Photocatalyst
Springer Science and Business Media LLC - Tập 33 - Trang 3454-3467 - 2023
Iqra Maryam, Tahir Iqbal, Sumera Afsheen, Atif Mossad Ali
For the degradation of MB dye, pure and Ta-doped (1 to 5%) WO3 nanoparticles (NPs) have been synthesized in the current work. Facile and efficient hydrothermal method has been carried out to synthesize pure and Ta-doped WO3 NPs. By using SEM, XRD, UV–Vis, PL, FTIR and Raman spectroscopy analysis, the morphological, structural, optical, and spectral features have been addressed. Due to the well-mat...... hiện toàn bộ
