Abstract A series of epoxy resin (EP)/octa(aminpropyl)silsesquioxane (POSS‐NH 2 ) organic–inorganic hybrid composites (EP/POSS‐NH 100/0, 95/5, 90/10, and 80/20 wt/wt) were prepared by melt casting then curing. Viscoelastic mechanical properties these studied dynamic analysis testing, respectively. Scanning electron microscopy was used to study the micromorphologies elucidate toughening mechanisms POSS‐NH . POSS units incorporated into network showed good compatibility with matrix. Phase...
Abstract The curing behavior of a difunctional epoxy resin/octa(aminopropyl)silsesquioxanes hybrid resin system using 4,4′′‐diaminodiphenyl sulfone as agent was studied. Fourier transform infrared (FTIR) spectroscopy used to evidence the formation and monitor process. Results showed that reactivity slightly lower than pristine resin. Differential scanning calorimetry study kinetics resins analyzed by two methods: Kissinger Flynn‐Wall‐Ozawa methods. FTIR analysis accorded well with results...
Abstract The thermodegradation kinetics of a hybrid inorganic–organic epoxy system formed by diglycidyl ether bisphenol A, DGEBA/DDS, modified with octahedral oligomeric silsesquioxane, octa(aminopropylsilsesquioxane) was studied. average activation energy this calculated the integral method developed Flynn–Wall–Ozawa ( E = 105.01 kJ mol −1 ) and Coats Redfern 113.07 ). Lifetime half‐life time materials were predicted using kinetic parameters. results obtained from two methods accorded well...
Abstract Cyanate esters with excellent high‐temperature properties and easy processing are well known as good resin materials used in aerospace electrical industries, but the drawback of brittleness limits their usage. In this study, carboxyl‐terminated liquid butadiene‐acrylonitrile (CTBN) was introduced to improve toughness bisphenol A dicyanate (BADCy), a typical kind cyanate esters. Fourier transform infrared spectroscopy differential scanning calorimetry were employed investigate...
Styrene–butadiene rubber (SBR) was reinforced with silica (SiO 2 ) by co-coagulating process. This study investigated the SiO amount, stirring time and pH value affecting content, curing characteristics mechanical properties of SBR. Results showed that content reinforcing behavior were greatly influenced amount value. The torque, tensile strength elongation at break optimal when mass fraction 21.5 wt%, 6 h 6.57. utilized efficiency decreased increasing but increased time. optimum cure . Both...
The surface properties of bastnaesite and parisite are similar to their associated gangue mineral, fluorite, which makes the flotation separation these two rare earth minerals from fluorite one industry’s most significant challenges. This study systematically investigates inhibitory effects mechanisms sodium silicate (SS) on bastnaesite, parisite, in an octyl hydroxamic acid (OHA) collector system through experiments, various modern analytical methods, DFT simulations. test results indicate...
The surfaces of high-modulus poly ( p-phenylene-2, 6-benzobisoxazole) (HMPBO) fibres have been treated by a solution polyphosphoric acid/acetic acid (PPA/AA). single fibre pull-out strength, chemical compositions and surface morphologies HMPBO were tested characterized tests, contact angles, X-ray photoelectron spectroscopy, atomic force microscope, scanning electron microscopy thermogravimetric analyzer. Results show that this method has great potential in the treatment fibres.
