Product Description

Overview of Industrial Grade Multiwalled Carbon Nanotubes Powder MWCNTs 20-40nm with Purity 95%

Carbon nanotubes (CNTs) are cylindrical nanostructures consisting of a single sheet of rolled-up graphene, a two-dimensional lattice of carbon atoms. Discovered in 1991, CNTs exhibit extraordinary properties due to their unique molecular structure, making them one of the most promising materials in nanotechnology. They can be single-walled (SWCNTs) or multi-walled (MWCNTs), differing in the number of concentric carbon layers.

Features of Industrial Grade Multiwalled Carbon Nanotubes Powder MWCNTs 20-40nm with Purity 95%

  1. Exceptional Strength and Stiffness: CNTs are among the strongest and stiffest materials known, with tensile strengths up to 60 times greater than steel.

  2. Lightweight: Despite their strength, CNTs are extremely lightweight, with a density close to that of graphite.

  3. High Thermal and Electrical Conductivity: They can conduct heat and electricity far better than copper, silver, or gold, with electrons flowing freely along the tube's length.

  4. Chemically Inert: CNTs are highly resistant to chemical reactions and corrosion, maintaining their properties in harsh environments.

  5. Flexibility: They can be bent or twisted without breaking, displaying excellent flexibility alongside their strength.

  6. Large Surface Area: CNTs have an incredibly high surface area to volume ratio, enhancing their effectiveness in adsorption and catalytic applications.

Parameter of Industrial Grade Multiwalled Carbon Nanotubes Powder MWCNTs 20-40nm with Purity 95%

Industrial grade multiwalled carbon nanotubes powder (MWCNTs) of diameter between 20-40 nm and purity of 95% can be obtained by chemical vapor deposition (CVD) process. The process involves heating a substrate to high temperatures, allowing carbon atoms to evaporate from the surface and form nanotubes. The size distribution of the nanotubes is typically controlled by adjusting the temperature during CVD. Here are some general steps involved in the synthesis: 1. Preparation of substrates: Clean and dry the substrate using an ultrasonic cleaner or sandpaper. 2. Target growth stage: Choose a suitable growth stage for MWCNTs, such as a low temperature regime (e.g., 600-700°C) for smaller diameter nanotubes or a higher temperature regime (e.g., 800-1000°C) for larger diameter nanotubes. 3. Catalyst preparation: Use a catalyst material that promotes the formation of carbon nanotubes. Common catalysts include transition metal oxides (such as MoOx and CrOx), hydrocarbons, and co-functionalized materials. 4. Growth conditions: Optimize the growth conditions for CVD, including the substrate temperature, pressure, and flow rate, to achieve the desired size distribution and nanotube quality. 5. Post-growth treatment: After growth, remove any unwanted material, such as impurities or debris, and perform purification techniques, such as spin-coating or chemical precipitation, to refine the product. 6. Quality control: Evaluate the purity, diameter distribution, and mechanical properties of the synthesized MWCNTs using standard characterization techniques, such as X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and thermal analysis (TGA). By following these steps and optimizing the growth conditions, you can obtain industrial-grade MWCNTs with a high purity and good mechanical properties. Note that the specific synthesis parameters may vary depending on the chosen catalyst, growth condition, and purification methods, so it's essential to experimentally determine the optimal settings for your particular application.

FAQs of Industrial Grade Multiwalled Carbon Nanotubes Powder MWCNTs 20-40nm with Purity 95%

Q: Is Industrial Grade Multiwalled Carbon Nanotubes Powder MWCNTs 20-40nm with Purity 95% safe for human health and the environment? A: Concerns have been raised about the potential toxicity of CNTs, particularly their respirable forms, which may resemble asbestos fibers. Research is ongoing to establish safe handling practices and assess long-term environmental impacts.

Q: How is Industrial Grade Multiwalled Carbon Nanotubes Powder MWCNTs 20-40nm with Purity 95% produced? A: There are several methods to produce CNTs, including arc discharge, laser ablation, and chemical vapor deposition (CVD), with CVD being the most common for industrial-scale production.

Q: Can Industrial Grade Multiwalled Carbon Nanotubes Powder MWCNTs 20-40nm with Purity 95% be seen with the naked eye? A: No, due to their nanoscale dimensions (typically 1-100 nanometers in diameter), CNTs are invisible to the naked eye and require electron microscopy for visualization.

Q: Is Industrial Grade Multiwalled Carbon Nanotubes Powder MWCNTs 20-40nm with Purity 95% expensive? A: Historically, CNTs were very expensive due to complex synthesis processes. However, advances in production methods have lowered costs, though they remain more expensive than many conventional materials.

Q: How does Industrial Grade Multiwalled Carbon Nanotubes Powder MWCNTs 20-40nm with Purity 95% compare to graphene? A: Both are forms of carbon with exceptional properties, but graphene is a flat sheet while CNTs are tubes. Graphene offers superior in-plane conductivity, while CNTs excel in out-of-plane conductivity and have additional mechanical advantages due to their tubular structure.
