A surfactant-assisted hydrothermal route has been presented to one-pot synthesized Ni nanoparticles encapsulated in Mg(OH)2 hollow spheres. The diameter of cores and the thickness shells are about 60–80 15 nm, respectively, size a whole composite sphere is approximately 70–100 nm. Benefiting from ferrimagnetic behavior high surface area shells, Ni@Mg(OH)2 nanocomposites exhibit excellent heavy metals adsorption capacity recyclable property. first removal efficiency almost 100% for target...
Chromium carbide nanopowders were synthesized by mechanical alloying-assisted microwave heating. The effect of gamma irradiation on phase composition and microstructure chromium the heating method was analyzed. samples characterized X-ray diffractometry (XRD), photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission (TEM), high-resolution (HRTEM) techniques. results showed that well-dispersed can be maintaining temperature at 1000 °C for 1 h. Gamma ray had an...
In this paper, polylactide (PLA)/wood flour (WF)/calcium carbonate (CC) composites with different content of poly(maleic anhydride -co- vinyl acetate) (PMAVA) were prepared. PMAVA was obtained by radical solution polymerization and identified FTIR. The torque - time curves showed that the balance torques PLA/WF/CC improved adding PMAVA. SEM photographs after addition PMAVA, compatibility interfacial adhesion between filler (CC or WF) PLA in each composite increased. DSC heating two cold...
Abstract The ratio of poly(lactic acid) (PLA), poly(butylene adipate- co -terephthalate) (PBAT), and calcium carbonate (CaCO 3 ) fillers in PLA/PBAT/CaCO composites was set at 90/10/5, 70/30/5, 30/70/5. effect nano- micro-CaCO on the melting crystallization performance investigated by differential scanning calorimetry. PLA related to PBAT ratio, cooling rate, CaCO particle size composites. Nano-CaCO prevented 90/10/5 70/30/5 but did not prevent Unlike nano-CaCO , regardless ratio. Nano-...
Quaternary phosphonium cationic starch (St-g-AM/ATPPB) flocculant was synthesized by using corn and acrylamide (AM), allyl triphenyl bromide binary (ATPPB) through simultaneous gamma-irradiation. The chemical structure of the copolymer characterized FTIR (Fourier transform infrared spectroscopy) 1H NMR (nuclear magnetic resonance) technologies. effects absorbed dose in range 1 to 6 kGy, AM/ATPPB ratio starch/(AM + ATPPB) on grafting flocculation were investigated. At a starch:AM:ATPPB wt...
CaO and MgO were used to neutralize aluminum dihydric tripolyphosphate (ADTP) by co-grinding, the effects of on anticorrosive performance ADTP mild steel studied. The efficiency resulting multicomponent pigments as corrosion inhibitors for boards in 3.5% w/w NaCl solution was determined electrochemical measurements. results showed that depended component feeding order ADTP, CaO, grinding. ADTP/MgO/CaO displayed more high than others, which attributed relatively integrated passivating film...
Abstract In this paper, poly(butylene succinate) (PBS)/polylactide (PLA)/poly(vinyl acetate) (PVAc) ternary blends were prepared via directly blending. The content of PBS in each sample was fixed at 30 wt% and that PVAc different, 2, 4 or 6%. PBS/PLA (30/70, g/g) PLA/PVAc (66/4, also for comparison. XRD DSC results showed miscible with PLA, the crystallinity ( X c ) PLA increased by adding PBS, but PBS/PLA/PVAc reduced PVAc. SEM images dispersed as droplets blend addition improved...
Abstract Cationic starch‐based hydrogels were synthesized by simultaneously irradiating starch, acrylamide (AM), dimethyldiallylammonium chloride (DMDAAC), and N , ′‐methylenebisacrylamide (MBA) in aqueous solution. A mechanism for hydrogel formation was proposed, the product characterized NMR spectroscopy.
