Spherical aluminum oxide nanoparticle synthesis and monolayer film assembly

What is Spherical aluminum oxide?

Spherical aluminum oxide powder refers to the aluminum oxide powder material made of specific irregular corner particles by the process of the flame method. A small surface area and good liquidity feature it.  Alpha Al2O3 spherical shape powder can be evenly dispersed in the organic body, and the formation of the most closely stacked gets a high filling, low viscosity, and high thermal conductivity mixture. At the same time, alpha Al2O3 spherical shape powder can reduce wear and tear in mixers, molding machines, and mold equipment to extend the service life of the equipment.

Spherical aluminum oxide nanoparticle synthesis and monolayer film assembly

Aluminum oxide is an important ceramic material for coatings and catalyst support for high-temperature applications. In this work, spherical aluminum oxide (AlOx) nanoparticles (NPs) are synthesized via the thermal decomposition of aluminum oleate using oleic acid as a stabilizing agent. X-ray diffraction analysis confirms its crystallization to γ-Al2O3 and α-Al2O3 after annealing at 700 and 1100 °C, respectively, revealing their gradual phase transition. Morphological and crystallinity changes of spherical nanoparticles upon annealing were investigated by transmission electron microscopy. The chemical composition and phase transitions to Al2O3 NPs were supported by X-ray photoelectron spectroscopy as a function of temperature. Monolayer assembly of as-synthesized NPs onto quartz substrate was performed using organic linker molecules (11-phosphonoundecanoic acid), confirmed by atomic force microscopy imaging. The optical band gap of the monolayer assembly was evaluated after annealing at different temperatures along with transmittance properties to compare with the current literature by UV–visible spectroscopy.
