Electrically conductive nanocomposites based on an open cell polyurethane foam were fabricated by dip‐coating of the PU in a cross‐linkable doping solution. The solution was prepared mixing room temperature vulcanizing silicone rubber, and hybrid filler systems consisted carbon black graphite nanoplates n‐hexane as solvent. influence types GN: CB ratio at constant concentration, electrical conduction, dielectric properties frequency range 10 ° –10 5 Hz, electromagnetic wave interference...
In this study, electrical properties and electromagnetic interference shielding effectiveness (EMI SE) of composites based on room temperature vulcanizing silicone rubber (RTV‐SR) hybrid conductive fillers (carbon black [CB]) graphite nanoplate [GNP]) were studied. The role GNP/CB ratio developed networks, properties, as well (EMI) was investigated in comparison with SR/CB SR/GNP composites. Dielectric controlled by the dominant filler phase. Nevertheless, all nanocomposites a higher...
The effect of stearic acid-coated nano calcium carbonate (NCC) on transitions and chain mobility poly(lactic acid) (PLA) was investigated. Dispersion state NCC in polymeric matrix explored using scanning electron microscopy surface tension component measurements. Trends PLA transitional phenomena were investigated the results dynamical mechanical analysis (DMA) differential calorimetry (DSC) nanocomposite systems based NCC. In addition, two types crystal structures decreasing glass...
Abstract Nanoscale Organic Hybrid Materials (NOHMs) consist of polymers tethered to a nanoparticle surface, and NOHMs formed with an ionic bond between the polymer have been proposed for electrochemical applications. exhibit negligible vapor pressure, chemical tunability, oxidative thermal stability, high conductivity making them attractive in reactive separation systems. In this study, are synthesized by tethering Jeffamine M2070 (HPE) SiO 2 nanocores via (NOHM‐I‐HPE) covalent (NOHM‐C‐HPE)...
The correlation among chemical structure, mesoscale and ion transport in 1,2,3-triazole-based polymerized ionic liquids (polyILs) featuring comparable polycation polyanion backbones is investigated by wide-angle X-ray scattering (WAXS), differential scanning calorimetry, broadband dielectric spectroscopy (BDS). Above the glass transition temperature,
Highly flexible nanocomposites based on room temperature vulcanizing (RTV) silicon rubber, conductive nano system comprised of high structure carbon black (CB) and graphite plates (GNP) were fabricated by solution processing method. Electrical properties EMI shielding effectiveness generated various ratios CB/GNP measured compared with the binary SR/CB SR/GNP. The composites prepared showed higher electrical conductivity lower percolation threshold than SR/GNP counterparts. hybrid to be...
In this study, the relationship between chemical structure, nanoscale organization, and ion transport in 1,2,3-triazolium polymerized ionic liquids (PILs) was investigated by wide-angle X-ray scattering (WAXS) broadband dielectric spectroscopy (BDS). Analyzing WAXS BDS results indicated that mobile types structure of pendant groups controlled structural heterogeneity conduction PILs below T g . The normalized length extracted from data used to correlate activation energy. For polycation...
