​The core reason why surface treatment is necessary for submicron high-purity alumina micro powder (usually with a particle size between 100nm and 1 μ m) is that its huge specific surface area leads to extremely high surface energy. This physical property causes it to exhibit serious' side effects' in its untreated state. Submicron high-purity alumina micro powder is prone to agglomeration due to its small particle size, large specific surface area, and high surface energy, which is a common problem in its application. To solve this problem, it is necessary to comprehensively consider the three dimensions of physics, chemistry, and technology, and choose the most suitable depolymerization solution.

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 16th China International Powder Metallurgy & Hard Alloy Exhibition, also known as PM CHINA, is the flagship event of the global powder metallurgy industry. Since its establishment in 2008, it has grown at an astonishing rate of 30% annually, from a few hundred square meters to a massive 40,000 square meters in 2023. With its extensive international reputation and global influence, PM CHINA has become a must-attend event for companies worldwide.

The combination of flexibility and elasticity makes elastic materials essential in a wide range of industries, including automotive, construction, and consumer goods. Moreover, they are increasingly attractive in emerging fields such as microfluidics, soft robotics, wearables, and medical devices. However, having sufficient mechanical strength is a prerequisite for any application. Thus, solving the seemingly contradictory attributes between softness and strength has always been an eternal pursuit.

​The difference in cohesive force between different powders is due to the type and strength of interparticle forces (van der Waals forces, capillary forces, electrostatic forces, etc.), and its core influencing factors include particle size, surface roughness, moisture content, and material properties, resulting in cohesive force that can span multiple orders of magnitude (from 10 ⁻⁶ N to 10 ⁻¹ N). This difference can be quantitatively described through the aggregation feature index, surface tension, and roughness correction model.

The fusion of nanotechnology and textile engineering has led to the development and improved performance of multifunctional smart materials in various application fields. One recent breakthrough is the one-step synthesis of AgNPs/CNTs spray-coating solution, which is used to anchor silver nanoparticles on multi-walled carbon nanotubes and apply them onto nonwoven fabric to create multifunctional smart textiles.
