Achievement of high conductivity and electrochemical window at ambient temperature for an all‐solid polymer electrolyte used in lithium ion batteries is a challenge. Here, we report the synthesis and characterization of a novel solid‐state single‐ion electrolytes based on comb‐like siloxane copolymer with pendant lithium 4‐styrenesulfonyl (perfluorobutylsulfonyl) imide and poly(ethylene glycol). The highly delocalized anionic charges of SO2N(–)C4F9 have a weak association with lithium ions, resulting in the increase of mobile lithium ions number. The designed polymer electrolytes possess ultra‐low glass transition temperature in the range from −73 to −54 °C due to the special flexible polysiloxane. Promising electrochemical properties have been obtained, including a remarkably high conductivity of 3.7 × 10−5 S/cm and electrochemical window of 5.2 V (vs. Li+/Li) at room temperature. A high lithium ion transference number of 0.80, and good compatibility with anode were also observed. These prominent characteristics endow the polymer electrolyte a potential for the application in high safety lithium ion batteries. © 2017 Wiley Periodicals, Inc. J. Appl. Polym.

“…The initial degradation temperature of the modified compositions of PU were observed to be enhanced indicating the strong chemical bonds formed between the urethane‐epoxy‐siloxane linkages and the good dispersion of nanoparticles in the SNC. The onset decomposition temperature of SNC was similar to that of PES due to the presence of a minute quantity of SNPs . Here the presence of PDMS gives the thermal stability to the nanocomposite.…”

The effect of incorporation of silver nanoparticles (SNPs) in an organic–inorganic metal nanocomposite was investigated. A renewable resource‐based polyurethane (PU) was synthesized by an in situ polymerization method with a polyol: diisocyanate ratio of 1:1.2, an epoxy (glycidol) terminated polyurethane (PE) was prepared by a polyol: diisocyanate: glycidol ratio of 1:3:3, a hydroxy terminated poly (dimethyl siloxane) (HTPDMS) modified PE (PES) was synthesized by the incorporation of 10 wt.% of HTPDMS into the PE and a silver nanocomposite (SNC) was synthesized by the addition of 0.3 wt. % SNPs into the PES matrix. Fourier transform infrared spectroscopy analysis confirmed the existence of NHCOO, Si‐O‐Si and oxirane linkages. The structural analysis was carried by X‐ray diffraction analysis in order to verify the face centered cubic structure of SNPs. The differential scanning Calorimetry analysis and thermogravimetric analysis showed the improved thermal stability by the addition of thermally stable epoxy linkages, high energy siloxane linkages and SNPs. Thus an advanced composite material with desirable properties for industrial applications have been prepared in the current work. POLYM.

“…UV irradiation of the poly(St)-poly(MMA)/SN nanocomposite, whose matrix microphase structure consists of cylindrical domains of poly(MMA) with 20 nm diameter, distributed in a continuous poly(St) phase, leads to photodecomposition of poly(MMA) and the partial removal of the attached SN aggregates. In this case, the ester groups of the MMA fragments were found to participate in the reaction with the SN, even though the energy of the Ag···RO 2 C bond is rather low [79,101]. Depending on the chemical structure of poly(MMA) and the method of its preparation, other functional groups may participate in formation of the hybrid structure.…”

“…The use of copolymers with different structures and functionality permits controlled variation of the morphology of the SN as well as the structure and properties of the hybrid composites [98][99][100]. For example, a high content of siloxane fragments in the structure of the poly(methyl methacrylate)-PDMS block copolymer (poly(methyl methacrylate) = poly(MMA)) imparts enhanced hydrophobicity and thermal stability to its derived nanocomposites but a high concentration (>7 mass %) of SN is required to impart bactericidal activity to these materials [101].…”

The major methods for the preparation of silver-containing polymer composite nanosystems and the formation of their hybrid structure are examined. Special attention is focused on a new class of silver-containing hybrid systems, namely, organic-inorganic coordination polymers, obtained by the self-assembly of silver complexes. The effect of intercomponent interaction on the structure and properties of these hybrid composites was examined.The creation of new improved materials is an important goal of modern chemistry and materials science. Polymer composites with hybrid structure are among such materials and hold interest since they display a combination of properties characteristic for each of the inorganic and organic components [1-3] and, in some cases, unique properties related to the specific nature of their structure [4]. From a modern viewpoint, hybrid organic-inorganic materials are formed by the combination of components, differing in their chemical nature, on a molecular or nano level through formation of chemical bonds ((non)covalent bonds, hydrogen bonding, and donor-acceptor bonds) or weaker physical bonds (van der Waals and electrostatic interactions) [5]. Special attention is given to the stability of the nanodispersed components due to interaction between the nanophase and various stabilizers [6]. The interest in silver-containing hybrid polymer composite materials, including nanocomposites, which, by their very nature, are a priori hybrid systems, is attributed to a set of properties of the matrix itself, which often possesses hybrid structure, properties of silver in ionic and nanodispersed forms, and new properties related to the appearance of hybrid silver-polymer structures [7,8]. Special interest is presently found in bionanocomposites derived from biopolymers and silver nanoparticles (SN), which display specific physicochemical properties, in particular, electrochemical, photochemical, and catalytic properties highly dependent on the dimensions and polydispersion of the nanophase [9, 10] as well as biological activity due to the ionization of the metal atoms in the presence of H 2 O/O 2 and the interaction between the SN surface and functional groups of the various biomolecules [11].In light of the important role of the polymer matrix in formation of the major structural characteristics and properties of silver-containing hybrid systems, we should classify these materials according to their chemical structure.Composites with Silver Nanoparticles (SN) Dispersed in a Polymer Matrix with Hybrid Structure. The major distinguishing feature of such materials is the prior synthesis of the hybrid polymer matrix obtained due to the formation of chemical bonds between the organic and inorganic components with subsequent introduction of SN into the system. The synthesis of the SN may be either in situ or ex situ. 740040-5760/15/5102-0074
