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.

One month later - Pros & Cons
Size: 10 Little Kid, Color: Cobalt Blue, Size: 10 Little Kid, Color: Cobalt Blue
I purchased these shoes for my three year old son who is really hard on his shoes. I wanted shoes that were a good price value and that my son could put on and take off by himself, run around in, and that would stand up to 3 year old kid abuse. These shoes fit the bill, and for the price I would recommend them and I would buy them again, but they'd be even better if they were even more reinforced around the toes. **This is NOT a paid or subsidized review. If you find this review helpful, please click "yes" - thank you! PROS: * Price - these are a well made, good looking shoe for a very fair price. * Easy for my son to put on and take off, but do not fall off. Velcro is holding up well so far. * The velcro tab that holds them on is big, so there's plenty of room for error in putting them on, and there's plenty of velcro to ensure a good hold. * Nice looking - my son likes them which is a big deal when you're three. * Stand up well to rough and tumble play * Lightweight * Good grip on the soles of the shoes. * Fit is as expected, no discomfort, he wears them all day long without complaint. CONS: * As with all kids shoes, the toe area could be even more reinforced although he's worn them every day for a month and, as you can see in the pictures, they're not showing much wear. * VERY lightweight - so if you're looking for a heavier, more protective shoe for any reason, this is not the pair for you. Overall I'd highly recommend these shoes, and would purchase them again.

Easy 2-Velcro closure
Bought the first pair at Kohls, was a favorite easy velcro closure for our 2.5 yr old Grandaughter. Wanted pink and Amazon had these. Perfect fit one half size up. They run a little narrow and smaller but are lightweight and easy for a toddler to put their own shoes on! Her favorite.

run small.
Size: 7.5 Little Kid, Color: Peri
I was a fool and didn't size up, our daughter was only able to sue them for a minute. Should have sized up 2 sizes, I know better. A bit chunky too which I forgot about with these shoes, but fun color and easy to put on.

Stylish and comfortable
Great for my toddler, very easy for him to walk in. They’re sturdy but lightweight and have good traction so he doesn’t slip. He does have really fat feet so the Velcro is a little tight if you’re between sizes with a fat foot toddler size up
