“…When treated with triethoxyvinylsilane using a US-assisted technique, the surface modification of the CaCO 3 NPs proceeds via the reaction of each Si-OC 2 H 5 group with the -OH groups on the surface of the CaCO 3 NPs. 200 The surface of CaCO 3 NPs can be modified with methacrylic, 201 myristic, 202 oleic acids, 203 and SA. 204 These acids are made up of two parts: a hydrophobic tail and a hydrophilic head.…”

“…In this study, we dispersed calcium carbonate (CaCO 3 ) particles in aqueous suspensions with various surfactants using wet-jet milling. CaCO 3 is currently being used in biological and industrial fields, such as in paper coating, paint, polymer molding, food, and preparation of clay materials, owing to its ease of production, high biocompatibility, and slow biodegradability [ 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 ]. Especially, the preparation of smaller sized CaCO 3 nanoparticles in a liquid phase is becoming essential to produce better functional properties in various fields since reducing the size of particle induces a larger specific surface area and a higher surface energy [ 23 , 24 ].…”

Dispersing particles in a liquid phase is significant for producing various functional nano/bio applications. The wet-jet milling method has been gaining attention as an attractive dispersing method in the preparation of soft material suspensions. This is because the main driving force of dispersion by the wet-jet milling method is the shear force, which is weaker than that it is in the ultrasonication dispersing method. In the wet-jet milling method, the pressure of the narrow channel which the liquid is passes through and the number of passes are used as the control parameters for dispersing the particles. However, the values of the pressure depend on the size (diameter and length) of the narrow channel, thus, it is not a commonly used dispersing parameter in dispersing by wet-jet milling to set the dispersing condition by various wet-jet milling instruments. In addition, wet-jet milling users must optimize the dispersing conditions such as the pressure and number of passes in the narrow channel, therefore, a simple prediction/optimization method of the dispersing size by the wet-jet milling method is desired. In this study, we established a novel colloidal dispersing concept, the dispersing energy input based on a calorimetric idea, for particle suspension preparation using the wet-jet milling method. The dispersing energy input by wet-jet milling was quantitatively calculated under various conditions during the dispersing by wet-jet milling, and then, the dispersing size of the particles was easily predicted/optimized. We demonstrated the usability of the concept by preparing aqueous suspensions of calcium carbonate (CaCO3) particles with various surfactants using the wet-jet milling method. Based on the established concept, in a case study on dispersing CaCO3, we found that changes in the micelle sizes of the surfactants played a role in wet-jet milling. The novel idea of the representation of energy input makes it possible to estimate the appropriate condition of the dispersing process by wet-jet milling to control the size of particles.
