Cut-resistant tungsten wire is a specialized tungsten-based material whose cut resistance, wear resistance, and ability to withstand extreme environments have been significantly enhanced through material modification technology. Its main performance characteristics can be summarized as follows:

Cut-resistant tungsten wire is a specially treated or modified tungsten-based material. Its core design objective is to enhance resistance to cutting, wear, and high temperatures, making it suitable for scenarios involving high mechanical stress or extreme environments.

In the vast field of materials science, the research, development and innovation of new materials have always been the core driving force to promote scientific and technological progress and industrial development. In recent years, tungsten oxide-based composite materials, with their unique physical and chemical properties and broad application prospects, have gradually stood out among numerous new materials and captured the attention of scientific researchers.

With the rapid development of technology in today's era, energy-related issues have become increasingly prominent. Energy storage technology, as a crucial link in the energy field, has received unprecedented attention. Supercapacitors, emerging as a shining new star in the energy storage industry, are gradually coming into people's view with their distinctive advantages and broad application prospects, thus becoming the "new darling" in the modern energy domain.

In the high-temperature industry, pure tungsten electrodes have emerged as indispensable core materials in welding, smelting, and plasma technology, thanks to their exceptional physical and chemical properties. As the single metallic element with the highest melting point, tungsten's stability in extreme environments makes it the preferred choice for processing high-melting-point metals and demanding processes.

Pure tungsten electrodes, as one of the earliest electrodes used in argon arc welding, have consistently played a significant role in the welding industry. This type of electrode, characterized by its high melting point, high density, corrosion resistance, and excellent electrical and thermal conductivity, has become an indispensable key material under specific welding conditions.

The types of tungsten electrodes are mainly classified according to the different rare earth oxides or alloy elements doped in them. Here are the common types of tungsten electrodes and their characteristics:

Tungsten disulfide nanosheet (WS₂ nanosheet) is a typical transition metal tungsten compound. There are many different preparation methods, each of which has its own unique principles, operation procedures, advantages and disadvantages.

Tungsten disulfide nanosheet (WS₂ nanosheet) is a typical two-dimensional nanomaterial with a large specific surface area, a low friction coefficient, good electrochemical performance, and optical properties. It has great potential in the fields of nanoelectronics, optoelectronic devices, flexible electronics, lubricating materials, and chemical catalysis. So, what are the factors that affect tungsten disulfide nanosheet performance?

Tungsten disulfide nanosheet (WS₂ nanosheet), as a typical transition metal sulfide material, is a semiconductor material with a hexagonal crystal structure (space group P6₃/mmc). Each layer is a sandwich structure formed by a W atomic layer sandwiched between two S atomic layers. Research indicates that a single layer of WS₂ has a direct band gap of about 1.8eV, enabling it to exhibit a quantum efficiency superior to that of indirect-band-gap semiconductors in the optoelectronic device field. The room-temperature carrier mobility of a single-layer WS₂ nanosheet can reach 100-300cm²/V・s, and the electron concentration is approximately 1×10¹²cm⁻², significantly outperforming traditional silicon-based materials. Notably, the electron mobility of WS₂ nanosheet shows obvious thickness dependence. For instance, the mobility of a 10-layer structure can drop to below 50cm²/V・s, closely related to the enhancement of interlayer phonon scattering.
