SiC powder is a widely used material in various applications such as electronic devices, coatings, and composites. However, its agglomeration and inadequate dispersion in aqueous media limit its efficiency. Therefore, surface modification techniques are essential to enhance the properties of SiC powder. This article discusses two methods for the surface modification of ultrafine SiC powder: PDADMAC and PSS modification and AC1830 surfactant modification.
Nano-aluminum oxide is a widely used material, especially in the field of nanotechnology, due to its unique physicochemical properties such as high surface area, high thermal stability, and excellent catalytic activity. However, the surface properties of nano-aluminum oxide play an important role in its performance in many applications. Therefore, surface modification of nano-aluminum oxide is essential to improve its properties for specific applications. In this article, we discuss one of the effective surface modification methods of nano-aluminum oxide, which involves using a silane coupling agent (KH-560).
The synthesis of carbon quantum dots can be mainly divided into two categories: top-down method and bottom-up method. Through the pre-treatment, preparation, and subsequent processing, carbon quantum dots can be controlled in size, passivated on the surface, doped with heteroatoms, and nanocomposites to meet the requirements.
Quantum dots (QDs) refer to semiconductor nanoparticles with a size smaller than the Bohr radius of the exciton and exhibiting quantum confinement effects. Due to the quantum confinement effect, the fluorescence emission of quantum dots is related to their diameter and chemical composition. By compounding with semiconductor surfaces, their optical and photochemical properties can be enhanced. Traditional quantum dots are mostly composed of heavy metal elements. Although their excellent performance has been widely used in fields such as biological imaging, electrochemistry, and energy conversion, heavy metal elements can cause environmental pollution and affect the health of organisms.
