In situ preparation and surface modification of barium sulfate nanoparticles

Surface and interface study of ZnO nanoparticles modified by octadecanol phosphate

“…It is attributed to the coating of the organic material on the surface of the nanoparticles. According to previous work, [23,24] ODP molecules deposited on the surfaces of the nanoparticles might be in the form of insoluble salts consisting of Zn(n-C 18 H 37 OPO 3 H) 2 and Zn(n-C 18 H 37 OPO 3 ). The layer of the insoluble salts on the surface of ZnO nanoparticles forms steric hindrance between nanoparticles and prevents the nanoparticles from aggregating.…”

Preparation and colloidal behaviour of surface-modified EuF3

“…The modifier molecules are not only a part of particles produced, but also limit particles growth and aggregation [13]. It promotes the obtaining of nanosized particles [5,6]. It was established [7] that citric acid adding during GdF 3 synthesis results in formation of particles with diameter from 10 to 150 nm.…”

“…CaCO 3 modification with sodium stearate and oleic acid, resulting in greater hydrophobicity, greater stability in nonpolar media and enhanced compatibility with nonpolar matrices, was used to obtain nanocomposites of poly(methylmethacrylate)-CaCO 3 [4]. The BaSO 4 surface coating with octadecyl dihydrogen phosphate is described in [6]. The modification process mechanism is suggested.…”

“…The modification in situ during ionic substance synthesis is mostly used [1,2,[5][6][7]. The modifier molecules are not only a part of particles produced, but also limit particles growth and aggregation [13].…”

Novel Method for the Preparation of Mesoporous BaSO4Material with Thermal Stability by Spray Pyrolysis

“…[5][6][7][8] Bala et al reported the preparation of BaSO 4 nano particles with selfdispersing properties without additional treatments with insitu preparation and surface modification of BaSO 4 nano particles. 9,10 Li et al reported the performance of barium sulfate nanotube arrays in supporting sulfates for lowtemperature methane activation and detailed information on the preparation of three types of mesostructured barium sulfate (lamellar, agglomerate and single nanotube) under various preparation conditions. 11,12 We reported the preparation of mesostructured barium sulfate with high surface area by dispersion method and its characterization.…”
