On June 19-21, the SAMPE China 2024 Conference and the 19th International Advanced Composite Material Product Raw Materials, Fixtures, and Engineering Applications Exhibition were grandly opened at the China International Exhibition Center.

At the exhibition, WINNER, a professional technology enterprise in the field of grinding and dispersion, presented a one-stop composite material preparation solution at the Chaoyang Hall in Beijing.

Carbon nanotubes (CNTs) are a new type of graphite material, which is a cylindrical structure formed by curling graphite layers, with a diameter range of generally one nanometer to several hundred nanometers. The length variation range of these tubular fibers is also large, generally ranging from a few micrometers to several thousand micrometers; Therefore, the length to diameter ratio (the ratio of length to diameter) of carbon nanotubes ranges from one thousand to one hundred thousand. In order to fully utilize the properties of a single carbon nanotube, it is necessary to uniformly disperse the carbon nanotube in the target matrix material.

This process scheme utilizes methods such as shear mixing, grinding, and cavitation to effectively disperse carbon nanotubes in liquids or molten materials. By adding surfactants or surface modification methods, the interaction between carbon nanotubes and dispersants can also be improved, thereby achieving maximum dispersion.

Further details on the preparation of carbon materials, such as stealth materials, composite materials, functional carbon materials, etc., will be provided by WINNER Intelligence for free on-site communication and testing services.
