Product Features

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.

8. Research field: commonly used in various scientific studies to help researchers explore the properties and potential applications of nanomaterials.

Perfect for Summer
Color: Pink
I ordered this portable fan for a trip to the Caribbean and it was perfect. It definitely kept me cool during the heat. It's small and lightweight and it has various settings for different levels of flow. It doesn't oscillate but that's fine with me. I've brought it with me on multiple trips so I'd say it's reliable and it has great power too. The blush pink color is so cute and feminine I love it!

Compact Fan That Actually Works Well
Color: Black
This ended up being a pretty solid little fan. The biggest strength is how compact and portable it is while still putting out a decent amount of airflow. Easy to throw in a bag, keep while traveling, or use outdoors without it feeling bulky. Build quality feels decent for the price. The plastic body is lightweight but doesn’t feel especially cheap or fragile. It feels designed for portability first, which is exactly what I wanted. One thing I did appreciate was that the blades don’t hurt if they accidentally hit your hand or finger. Small detail, but it makes the fan feel less annoying to use and probably safer around kids as well. The flashlight feature is honestly whatever for me. Nice that it exists, but not something I personally needed or would buy it for. The fan itself is the real value here. Pros * Compact and easy to carry * Good airflow for the size * Lightweight but reasonably well made * Fan blades are safe and don’t hurt on contact * Convenient for travel or outdoor use Cons * Flashlight feature feels unnecessary * Plastic construction is functional, not premium * Not powerful enough to replace a larger fan Final Thoughts Overall, this is a very practical portable fan that does exactly what it’s supposed to do. Compact, effective, and easy to keep with you. The extra features aren’t a huge selling point for me, but the core fan functionality works well enough that I’d still recommend it. Who It’s For Great for travel, theme parks, outdoor events, sports games, commuting, or anyone wanting a compact personal fan that’s easy to carry around.

Great product
Color: Pink
Fit in my purse and has a good battery life for as much as I use it. Enjoy that there’s two different air flows.

Perfect Wind Speeds, Size, Weight, and Price Here on Amazon Prime
Color: Pink
My wife uses this little fan when she experiences one of her occasional hot flashes. And she said it works well for these times. She also uses it when we are at an outdoor market or park when the temperature rises along with the humidity thus providing a little respite from the these conditions. She likes the size, weight, the included lanyard, and the fact that it is so quite when in use. A full charge seems to last for a two to three hours depending on the selected speed of the fan itself. There are other more powerful portable handheld fans available, however, this one seems to be the perfect compromise between air speeds, size, weight, and price.

I have 3!
Color: Pink
I love this fan! The high speed will cool you down quickly! It's great for church! ballgames! Beach! Hotflashes!!! It's very quite! You can hold it or put on a table and position it where you want. I have one for work, one at home and one in my purse. The oldest is about 4 years old and works as good as day one.
