In the fields of material processing and chemical production, coupling agents, crosslinking agents, and dispersants are three commonly used additives with different functions, but they all have a critical impact on material properties. The following provides a detailed explanation from the aspects of definition, main characteristics, typical types, and core differences. Coupling agent Coupling age...

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...

The meanings of metamorphic treatment, grain refinement, and primary phase refinement or morphology change are different, and sometimes the term metamorphic treatment is used to summarize these contents. (1) Deterioration treatment. For simple binary Al Si alloys, such as Z102 containing 11%~13% Si, it is a typical eutectic alloy. Its organization consists of coarse needle shaped (should be layere...

In transmission electron microscopy (TEM) analysis, the primary and crucial step in obtaining a high-quality image that can be interpreted reasonably is sample preparation. Inappropriate sample thickness, poor conductivity, or damage introduced during sample preparation can directly lead to abnormal electron beam penetration, image distortion, and even sample scrapping. TEM sample requirements ① T...

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...

With the increasing demand for high thermal conductivity materials, filled thermal conductive polymer composites have good application prospects. The performance of thermal conductive composite materials largely depends on the selection of thermal conductive fillers. Aluminum oxide (Al2O3)is a common ceramic filler with high hardness and good thermal conductivity, and is a commonly used choice to ...
