The demand for conductive paste in the photovoltaic industry and electronic packaging field is undergoing a transformation from high silver content to low silver or even silver free. Although silver powder has excellent conductivity and chemical stability, it is expensive, has limited resources, and is prone to electromigration. In contrast, copper's conductivity is second only to silver and its c...

Titanium dioxide has the characteristics of high chemical stability, non toxicity, and good photoelectric performance, especially rutile titanium dioxide has high surface activity, which is very suitable for battery material modification. Like polyethylene glycol, the introduction of titanium dioxide is also to compensate for the insufficient energy density and rate performance of lithium iron pho...

Although spherical silicon micro powder is spherical and has good fluidity, there are still problems of poor compatibility and difficult dispersion when used as an inorganic filler mixed with organic matrix materials. Therefore, surface modification is necessary to solve these problems. Surface modification of spherical silicon micro powder involves introducing specific functional groups or coatin...

With the rapid development of modern industry and technology, different industries have increasingly high performance requirements for powder materials. In addition to having extremely low impurity content, fine particle size, and narrow particle size distribution, powder materials also need to have a certain particle morphology. Spherical powders have been widely used in high-end industries such ...

What are nanoparticles? Nanoparticles (NPs) are typically defined as granular materials with at least one dimension at the nanoscale (1-100 nm) in three-dimensional space. From the dimensions of structure and morphology, nanoparticles can be classified into zero dimensional nanomaterials (0D nanomaterials), corresponding to one-dimensional (1D) and two-dimensional (2D) nanomaterials. 0D nanopartic...

1.Characterization of particle size and distribution Dynamic Light Scattering (DLS): DLS is one of the most commonly used techniques for measuring the particle size and distribution of nanoparticles in suspensions. It calculates the hydrodynamic diameter of particles by measuring the time-dependent light scattering intensity fluctuations caused by Brownian motion of particles. DLS can also provide...
