This study aimed to evaluate the effects of carbon nanofibers (CNFs) on performance liquid epoxidized natural rubber (LENR)-modified asphalt. The physical, adhesion and rheological properties were determined by several tests such as penetration, elastic recovery, ring ball softening point, Brookfield rotational viscometer, AFM dynamic shear rheometer. LENR was used at concentrations 3, 6, 9%, while CNFs contents 0.3, 0.4, 0.5% weight Conventional test results showed that increases in...
Abstract In this study, a novel biodegradable polymer electrolyte membrane with reduced fuel crossover, high selectivity, and conductivity compared Nafion 117 in direct ethanol cells (DEFCs) has been reported. Herein, polyvinyl alcohol/epoxidized natural rubber (PVA/ENR) blend membranes were synthesized via simple solution casting method applied DEFCs. The structural physicochemical features of the PVA/ENR examined using FESEM, FTIR, XRD, water absorption, uptake, swelling ratio oxidative...
Abstract Our work aims to investigate the morphology and properties of natural rubber (NR) dispersed in a polystyrene/silica hybrid nanomatrix. The nanomatrix structure was formed by graft copolymerization vinyltriethoxysilane onto NR grafted with styrene. This composed nanosilica size less than 100 nm, incorporation polystyrene resulted outstanding mechanical viscoelastic properties. tensile strength 23 MPa, storage modulus 2.54 which were 2.5 15 times higher those silica this material...
Poly(methyl methacrylate) (PMMA) grafted natural rubber (NR) latex was successfully prepared and solely exploited even at high MMA concentration (1.5 mol/kg-rubber) to make coherent uniform vulcanized films without blending with other polymer achieve excellent physical properties. High ammonia (HANR) subjected graft-copolymerization methyl methacrylate (MMA) monomer in the presence of tert-butyl hydroperoxide (TBHP) tetraethylenepentamine (TEPA). conversion, i.e., 85.12 mol%, grafting...
Natural rubber (NR) with an in situ nanosilica nanomatrix was characterized present work. The prepared via graft copolymerization of a silane monomer, vinyltriethoxysilane (VTES), onto deproteinized NR (DPNR) latex stage using tetrapentamine (TEPA)/ tert ‐butylhydroperoxide (TBHPO) as initiators. VTES conversion more than 80% obtained, and it depended on concentration. copolymer structure by Fourier transform infrared (FT‐IR), solution‐state proton nuclear magnetic resonance ( 1 H‐NMR),...
A simple and versatile method is reported for the synthesis of La(OH)3 on halloysite nanotubes (HNT) catalytic depolymerization liquid epoxidized natural rubber (LENR). The lanthanum nitrate was incorporated into HNT by impregnation method. characteristics these La(OH)3−HNT catalysts were investigated using SEM equipped with Energy Dispersive X-ray (EDX), X-Ray Fluorescence (XRF), Fourier-transform Infrared Spectroscopy (FTIR), Diffraction (XRD), Ultraviolet Visible Light (UV-Vis)...
Cu2+-HNT nanocomposite was synthesized via impregnation of CuSO4.5H2O onto halloysite nanotube (HNT). A portion the calcined at 550 and 900 °C respectively, to obtain CuO-HNT catalysts. The FTIR, XRD EDX results reveals successful formation nanocomposites. This is consistent with decrease in SBET pore volume for Cu2+-HNT, °C, when compared HNT. Optical properties both HNT, nanocomposites show a bandgaps GPC pristine LENR (P-LENR) photo-degraded showed that treated gives lowest molecular...
