Product Overview

Carbon nanotubes are simple substances composed of carbon atoms, which can be regarded as hollow tubular structures formed by the curling of graphene. On the surface of carbon nanotubes, carbon atoms form bonds with each other in the form of sp2 hybridized orbitals, arranged in a regular hexagonal graphite layer structure. In theory, this hexagonal structure is perfectly and uniformly distributed on the surface of the entire carbon nanotube. In terms of topology, the shared structure and properties between graphene and carbon nanotubes are one of the important factors contributing to their similar properties. However, due to the curvature of the graphite layer in carbon nanotubes and the potential defects that may occur during the growth process, sp3 hybridization may occur in the hexagonal ring structure on the surface of carbon nanotubes, leading to the formation of pentagonal or seven membered rings. Carbon nanotubes are classified into single-walled carbon nanotubes, double walled carbon nanotubes, and multi walled carbon nanotubes based on the curling of graphite sheets with different layers.

There are many preparation processes and methods for carbon nanotubes, and carbon nanotubes with corresponding properties and structures can be prepared through different methods. At present, the main methods for preparing carbon nanotubes include graphite arc method, laser evaporation graphite method, and chemical deposition method. Chemical deposition method has the advantage of large-scale production and is currently a widely used method.

Product Features

Multi walled carbon nanotubes have many unique properties:

Excellent mechanical properties: with extremely high strength and toughness. For example, its theoretical strength can reach tens or even hundreds of times that of steel.

Excellent electrical performance: can exhibit good conductivity, depending on aspect ratio, structure, and preparation method.

Good thermal performance: high thermal conductivity, capable of effectively transferring heat.

Large specific surface area: This makes it potentially applicable in fields such as adsorption and catalysis.


Application Fields

1. Composite material reinforcement: Multi walled carbon nanotubes have high strength and toughness. Adding them to matrices such as plastics, rubber, and metals can significantly improve the mechanical properties of the material, such as strength and stiffness. For example, grafting carbon nanotubes onto the surface of carbon fibers to obtain a multi-level structure can enhance the interfacial interaction with organic matrices and the mechanical properties of composite materials.

2. Electronic devices: Although their conductivity is not as single and excellent as single-walled carbon nanotubes, they still have good conductivity and can be used to manufacture high-performance conductive inks, sensors, flexible displays, and other electronic devices.

3. Electrode materials: Can be used as electrode materials for lithium-ion batteries and supercapacitors to improve energy storage and power output capabilities.

4. Catalysts and catalyst carriers: They can serve as catalysts themselves. It can also serve as a catalyst carrier, providing more active sites for catalytic reactions and enhancing catalytic performance due to its large specific surface area and unique structure. For example, acidified multi walled carbon nanotubes can be used as carriers to load composite inorganic salts, resulting in solid acid catalysts with superior catalytic effects than single component iron sulfate.

5. Energy field: In addition to the applications mentioned earlier in batteries, it can also be applied to hydrogen storage materials. The unique hollow structure and nanometer diameter of carbon nanotubes provide favorable conditions for hydrogen storage.

6. Absorbing materials: They have a certain ability to absorb electromagnetic waves and can be used to prepare absorbing materials. They have potential applications in military stealth, electromagnetic shielding, and other fields.

7. In the field of biomedicine: Its unique hollow structure and nanometer diameter can provide space for accommodating drugs, achieve high drug loading, and can pass through cell membranes and various biological barriers to deliver drugs to the inside of cells. In addition, it can effectively reduce the release rate of drugs and improve the sustained release effect.

Simple valet tray that finally keeps my pockets from exploding on the nightstand
Color: Black, Size: Sectional, Color: Black, Size: Sectional
This valet tray is one of those small things that makes daily life a little easier. I like the sectional layout because it gives everything its own spot instead of just tossing a pile of keys and a wallet together. The phone slot is angled so you can actually see the screen when it is sitting there, which is a nice touch. The inside lining feels soft so it helps with scratches and it also cuts down that loud clanking sound when you drop keys in it. The non slip base matters more than I expected since it keeps the tray from sliding when you grab stuff in a hurry. Size wise it fits the normal everyday carry stuff without being huge. If you want your entryway or nightstand to look less messy, this does the job.

Thoughtfully Designed Tray
Color: Black, Size: Sectional
Such a simple item, but Spigen was very thoughtful in some of the subtle design feature. This is not just a box with dividers. Each compartment is actually sloped, which makes grabbing an item ergonomic, allowing you to just pull something to the edge instead of the often awkward battle against the walled edges of a traditional design. Yes, it's just a tray, but I appreciate its thoughtful design.

Keep your essentials all in one place
Color: Black, Size: Sectional, Color: Black, Size: Sectional
Picked this up to declutter my nightstand and it’s honestly been a solid little upgrade. The layout is super practical, there are 4 compartments and they’re actually sized well, not just random sections. I can fit my keys, wallet, watch, and random small stuff without everything piling on top of each other. The phone slot is a nice touch too. It’s angled just enough that I can glance at notifications or watch something while it charges. Didn’t even miss having a cable hole like I thought I would. Build quality feels better than expected. It’s lightweight but still sturdy, and the outside has a clean, modern look. The inside lining is soft, so when you toss your keys or watch in, it doesn’t make that annoying clatter or scratch things up. Also appreciate the non-slip bottom, it actually stays put when you grab stuff instead of sliding all over the place. Overall, simple but well thought out. If you’re tired of your everyday carry stuff being scattered everywhere, this does the job nicely. For the price point, this is a great value 👌 👏

Spigen Modern Valet Tray
Color: Black, Size: Catchall, Color: Black, Size: Catchall
I'm a big fan of all Spigen products, I needed something to keep my nightstand as tidy as possible and took a chance with this tray, however I was a bit letdown on its quality. The tray has weird indentations on the very edge, I'm not sure if this is intended or if my product was damaged. The tray has nothing crazy going on, other than it has rubbery feet to prevent from sliding around your area. The size and fit are perfectly fine to keep my wallet, keys and headphones organized. I love the look of it, it has a great professional appearance, just a bit sad that it has those aforementioned weird markings on the edge. Tray was simple to use, nothing weird.

Soft Catch Tray
Color: Black, Size: Sectional, Color: Black, Size: Sectional
Pros: 1. Soft tray. Has almost a silicon type texture. Won’t scratch items you put in the tray. The segmented sections are the perfect size for wallet, keys, sunglasses, watches, etc. Phone section is slightly angled as well. 2. Rubber feet helps it stay in place and doesn’t slide. I have mine on top of my watch winder and it has moved even when throwing items on it. 3. Build quality is great. Has a textured hard bottom and soft inner. Everything has a nice finish. 4. Price is great for the quality received. Cons: 1. The silicon inner material is a dust magnet. Makes it difficult to keep clean. Summary: This is a great option for an organized tray. I am extremely happy with the quality and functionality of what I received. Spigen is always a great brand.
