Graphene, a two-dimensional material, has been the subject of intense research and development in recent years, owing to its unique properties such as high surface area, high electrical conductivity, and mechanical strength, among others. However, there are different types of graphene, each with its own characteristics and applications. In this blog post, we will discuss the two most popular forms of graphene - graphene oxide (GO) and reduced graphene oxide (rGO), and their differences.

Nanotechnology is becoming increasingly important in many fields, from medicine to electronics. Nanomaterials, including nanoparticles, nanotubes, and nanowires, are essential components of many nanotechnology applications. Producing these materials requires specialized techniques, such as wet and dry methods. In this article, we will explore what dry and wet methods are, their benefits, and how SAT NANO provides high-quality nanomaterials.

Silver coated copper technology is a composite metal material technology, and its core product silver coated copper powder is composed of copper in the core and silver shell covering its surface. A typical silver layer thickness is between 50-200 nanometers, with a silver content (mass ratio) of 5% -30%. In this structure, the copper core plays a role in providing low cost and high conductivity, while the silver shell is crucial in ensuring that the particles resist oxidation during processes such as pulping and printing, while forming good ohmic contact with the battery silicon wafer or TCO film. After sintering, the silver shell acts as a conductive medium, ensuring low contact resistance and reliable adhesion of the electrode, while the copper core reduces material costs while endowing the slurry with certain mechanical strength and thermal stability.

​Graphene coated copper and silver coated copper have essential differences in conductivity, each with its own advantages and disadvantages, and their applicable scenarios are also different.

​Dispersants or dispersing agents are substances that aid in the uniform distribution of particles or materials such as nanoparticles in a medium. Dispersing nanoparticles can be a challenging task due to their high surface area, tendency to agglomerate and their small size. In this article, we will discuss the basic principles of using dispersants in dispersing nanoparticles.

Colloidal gold refers to a colloidal system formed by suspending nanoscale gold particles in an appropriate solution. The size of gold particles typically ranges from 1 to 100 nanometers.
