Carbon Nanotubes FAQs
Q1: What is the surface area of OH or COOH functionalized CNTs?
A1: The surface area of functionalized CNTs depends on the degree of functionalization and the specific treatment process used. Typically, functionalized CNTs exhibit a higher surface area than non-functionalized CNTs due to the presence of oxygen-containing functional groups. This increased surface area makes them more reactive and better suited for applications like energy storage, catalysis, and sensor development.
Q2: Are OH and COOH functionalized CNTs dispersible in solvents?
A2: Yes, both OH-functionalized CNTs and COOH-functionalized CNTs are more easily dispersible in various solvents compared to non-functionalized CNTs. The presence of hydroxyl or carboxyl groups creates a hydrophilic or polar character, which improves the solubility and dispersion of CNTs in polar solvents like water, ethanol, and other organic solvents.
Q3: What is the typical particle size of OH or COOH functionalized CNTs?
A3: The particle size of functionalized CNTs can vary depending on the method of functionalization, but they typically remain in the range of 5-25um. However, the functional groups significantly enhance the dispersion of CNTs, ensuring that they remain uniformly dispersed in solutions, composites, and other materials.
