Product Name
Name:a>Industrial grade MWNTs 30-80 nm
Product Overview
Multi-walled carbon nanotubes are made of multilayer coiled graphene sheets and maintain a fixed distance between the layers, forming a coaxial circular tube structure. The tube diameter is usually between 5 and 30nm, and the length can range from a few microns to dozens of microns. The specific size depends on the preparation method and conditions. The purity of industrial-grade MWCNTs can reach 95% or higher, ensuring their stability and reliability in applications. The main preparation method of industrial grade multi-walled carbon nanotubes is chemical vapor deposition (CVD) method. In the process of CVD, carbon source substances (such as methane, acetylene, etc.) are decomposed and deposited into tubular structures under the action of catalysts (such as iron, cobalt, nickel, and other transition metals at high temperature). Precise control of the diameter, length and structural properties of MWCNTs can be achieved by controlling reaction conditions and the use of specific catalysts.
