Polyacrylate/silica nanocomposite materials prepared by sol–gel process
Polyacrylate/silica nanocomposite was prepared by sol–gel process via in situ emulsion polymerization. The influence of the synthetic conditions, such as the ratio of different monomers and the contents of tetraethoxysilane (TEOS), c-methacryloxypropyltrimethoxysilane (Z-6030), diethanolamine (DAM) and ammonium persulfate (APS) on the physical mechanical properties of polyacrylate/silica nanoco...
متن کاملSynthesis and characterization of Alumina (Al2O3) nanoparticles prepared by simple sol-gel method
Alumina is one of the most widely used ceramic materials as catalysts, catalyst supports and absorbents, and also wear resistant coating. This study focused on fabricating and characterizing of alumina ceramic nanoparticles fabricated using new and simple sol-gel method. Aluminium oxide (Al2O3) nanoparticles were synthesized by iron (III) nitrate 9-hydrate as precursor. Physicochemical properti...

متن کاملPreParatiOn Of nanO-SCale α-Al2O3 POwder by the SOl-gel methOd
Sol-gel method was applied to synthesize ultrafine nano α-alumina particles using aqueous solutions of aluminum isopropoxide and 0.5 M aluminum nitrate hydrate. Sodium dodecylbenzen suffocate and Sodium bis-2ethylhexyl sulfosuccinate were also used as surfactant stabilizing agents. The prepared solution was stirred for 48 hours at 60°C, then, the resultant gelled mass was dried at 90°C, and fin...
متن کاملSintering of Al2O3–Ceo2nanopowder Prepared by Co-Precipitation Method
In the present work, Al2O3-CeO2 composite nanopowders were synthesized via co-precipitation method. The sinterability of the synthesized powders was investigated. The results showed that the transformation of transition phases of alumina to α-Al2O3 takes place at 1200 °C. TEM images showed that the powders was composed of nanoparticles in the range of 30−70 nm. The densification of composites s...
