“…In order to improve the compatibility between the inorganic filler and the organic matrix, the surface of the inorganic filler needs to be modified by grafting with polymeric organic substances. [6][7][8][9][10] In this study, the polymerization of methyl methacrylate is initiated by free radicals, and the surface of nano-barium sulfate has been grafted with polymethyl methacrylate (PMMA), thus effectively solving the problem of nanobarium sulfate surface modification. Only a few papers on this type of chemistry have been reported to date.…”

“…Traditional methods often use organic solvent washing, 2 azeotropic distillation, 3 the inorganic dispersant method, 4 wet surface modification, 5 and other process methods to modify the barium sulfate treatment, so as to improve the material properties. The key to modification is to achieve ultrafine dispersion of nano-barium sulfate in the polymer.…”

In this paper, the wet modification method is compared with the grafting method to modify nano-barium sulfate. The effects of the modification method, the modification time, the modifier dosage, the modification temperature, and other factors on the degree of activation of modified nano-barium sulfate are investigated to solve the nano-barium sulfate agglomeration problems and to make it a suitable process for industrial production. Thermogravimetric analysis, infrared spectroscopy, and scanning electron microscopy are used to characterize the morphology and encapsulation of modified nano-barium sulfate. The grafting method is used to modify nano-barium sulfate with a modification time of 120 min, a modifier dosage of 27%, and a modification temperature of 80 °C. From the experimental results, a hydrophobic nano-barium sulfate in powder form with 76.86% activation degree and 77.41% oil absorption value is obtained.

Conventional barium sulfate is characterized by large particle size, crude manufacturing processes, and inferior quality. Conversely, ultrafine barium sulfate offers significant enhancements in product quality and broadens its range of applications. To achieve industrial-scale production of high-quality ultrafine barium sulfate, characterized by reduced particle size and narrow particle size distribution, a high-throughput tubular reactor was employed. Ultrafine barium sulfate with small particle size and narrow distribution can be effectively prepared without amplification effects using a high-throughput tubular reactor. This study investigates the influence of reactant concentration and feed flow velocity on particle size. The particle size of ultrafine barium sulfate exhibits a trend of decreasing and then increasing with the increase in reactant concentration. A minimum particle size of 28.17 nm can be achieved when the concentration of the reactant material is 1.2 mol L−1. The particle size decrease with an increase in the flow velocity of the reaction material. A minimum particle size of 28.17 nm for ultrafine barium sulfate can be achieved at a flow velocity of 10.42 m s−1. Furthermore, the product’s particle size and morphology were characterized utilizing a BET specific surface area analyzer and scanning electron microscope.
