Preparation and properties of epoxy semi-coated quartz sand proppant decorated with stearic acid functionalized TiO2 nanoparticles
In this work, the hydrophobic and oleophilic epoxy semi-coated quartz sand proppant decorated with stearic acid functionalized TiO2 nanoparticles is successfully prepared. The unique semi-coated structure is characterized by SEM, SDF, and TEM. Compared with raw quartz sand proppant, the water contact angle of the epoxy semi-coated quartz sand proppant can even reach 141.6°, which is due to the rough surface and hydrophobic coating induced by semi-coated epoxy and hydrophobic stearic acid-modified TiO2. Meanwhile, the water contact angle could be adjusted by controlling the weight content of quartz sand. Moreover, the semi-coated proppant can maintain its hydrophobicity after treated by boiling water for 4 h, indicating improved thermal stability. The physical properties including bulk density (1.44 g/cm3), apparent density (1.40 g/cm3), acid solubility (3.43%), and breakage rate (1.26%) of the semi-coated proppant decorated with stearic acid functionalized TiO2 nanoparticles are improved. The thermal stability, acid solubility, and flow conductivity are analyzed as well. This work could provide a new idea for the preparation of quartz sand proppant to enhance the petroleum and gas production through hydraulic fracturing technology.
期刊介绍：
Advanced Composites and Hybrid Materials is a leading international journal that promotes interdisciplinary collaboration among materials scientists, engineers, chemists, biologists, and physicists working on composites, including nanocomposites. Our aim is to facilitate rapid scientific communication in this field.
The journal publishes high-quality research on various aspects of composite materials, including materials design, surface and interface science/engineering, manufacturing, structure control, property design, device fabrication, and other applications. We also welcome simulation and modeling studies that are relevant to composites. Additionally, papers focusing on the relationship between fillers and the matrix are of particular interest.
Our scope includes polymer, metal, and ceramic matrices, with a special emphasis on reviews and meta-analyses related to materials selection. We cover a wide range of topics, including transport properties, strategies for controlling interfaces and composition distribution, bottom-up assembly of nanocomposites, highly porous and high-density composites, electronic structure design, materials synergisms, and thermoelectric materials.
Advanced Composites and Hybrid Materials follows a rigorous single-blind peer-review process to ensure the quality and integrity of the published work.
