Product Description

Overview of Supply electromagnetic shielding material 99% MWCNT Multi-Walled Carbon Nanotube

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 Supply electromagnetic shielding material 99% MWCNT Multi-Walled Carbon Nanotube

  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 Supply electromagnetic shielding material 99% MWCNT Multi-Walled Carbon Nanotube

MWCNT (Multi-Walled Carbon Nanotubes) is a type of carbon nanotube that has a unique electronic, mechanical, and thermal properties due to its high surface area, low density, and strong correlation with other materials. The effectiveness of MWCNT in providing electromagnetic shielding depends on several factors such as the material's surface roughness, size, and shape. The efficiency of MWCNT-based electromagnetic shielding depends on the length and diameter of the nanotubes, as well as the frequency and energy of the applied magnetic field. According to published research, MWCNTs can provide up to 75% effective shielding for magnetic fields ranging from 0.1 to 2 Tesla, with higher shielding at lower frequencies. In terms of parameter analysis, the most commonly used parameters to evaluate the performance of MWCNT-based shielding include: * Surface roughness: This parameter measures the degree of deviation from flatness or lamination of the nanotubes' surface. Higher surface roughness leads to better screening against charged particles. * Size distribution: This parameter describes the distribution of MWCNT sizes in the nanotubes. Smaller MWCNTs tend to have larger surface areas, which makes them more effective at absorbing charged particles. * Shape: Different shapes of MWCNTs may have different absorption profiles, which can affect their shielding performance. For example, flat MWCNTs may be less effective at blocking charged particles than cylindrical MWCNTs. Overall, MWCNT-based electromagnetic shielding can be an effective tool for protecting sensitive electronic equipment from external magnetic fields. However, it is important to carefully select and tune the material's parameters to achieve optimal performance.

FAQs of Supply electromagnetic shielding material 99% MWCNT Multi-Walled Carbon Nanotube

Q: Is Supply electromagnetic shielding material 99% MWCNT Multi-Walled Carbon Nanotube 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 Supply electromagnetic shielding material 99% MWCNT Multi-Walled Carbon Nanotube 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 Supply electromagnetic shielding material 99% MWCNT Multi-Walled Carbon Nanotube 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 Supply electromagnetic shielding material 99% MWCNT Multi-Walled Carbon Nanotube 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 Supply electromagnetic shielding material 99% MWCNT Multi-Walled Carbon Nanotube 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.
