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.

Can't choose the dino... sad!
I have a beagle/jack russel mix. Needless to say, he is very high-energy and does best when given a job to do that involves chewing. He LOVES his Novabone and Nylabone- but tears thru the larger sizes in a single afternoon- so when I saw this I was very happy, because it is an unusual shape and durable! Amazon's iphone app let you scan in an item and find it cheaper on Amazon- so instead of the higher pet shop price, I scored a savings deal on Amazon! Nice! My big, fat, sad complaint is that you cannot CHOOSE the dinosaur! I knew this when ordering and the stegosaurus arrived- honestly I was hoping for the T-Rex or the Brontosaurus but I guess you get what you get. Still, a beagle gnawing on a T-Rex would be pretty funny...

Great Toy for Teething and Strong Chewer
Eli is now 10 months old, a labrador retriever that proves time and time again he needs toys that he can chew, but won't fall apart. He cannot have the stuffed animal toys (no, those he'll tear apart in SECONDS, never mind minutes). Aside from the Kong and the antler, this is the only toy he can chew on that won't fall apart. Even animal bones will split in minutes. Since he was a couple of months old, he has loved this Dinosaur Chew Toy. When he was teething, I'd put it in the freezer (sometimes put peanut butter on it to keep his interest). It was not only great for teething, but also massaged his gums. Now that he's out of teething phase, he still loves to chew on it. For the money, this is worth it. It's saved the furniture and the house from being chewed on, as he focused on this toy instead. Highly recommend, especially for the price. For any strong-chewing pup or dog in particular, this toy won't shatter, split or break apart.

Cracked Tooth
Update: While I originally loved this product and so did my dogs, I feel the need to update this review. The Dura Chew Nylabones are incredibly hard, which is what makes them last so long. However, one of our dogs did crack a tooth recently from chewing on a Dura Chew. Since then, we have been very hesitant to allow any of our dogs to chew on these as other reviews also state that dogs have cracked teeth. We have since thrown out all of the Dura Chews that we had. We are still using the regular Nylabone products (when they aren't made in China), but once those are gone we will not buy any additional products from Nylabone. We have been buying Whimzees for our dogs for the last two years or so and they are a healthy edible alternative. They do not last as long because they are edible, but I have the peace of mind in knowing that my dogs are safe with them. Another healthy alternative would be antlers, which we also give to our dogs and they usually last a long time. Original review: Another great Nylabone product. I love that dogs can chew on Nylabone products and they can't pull off pieces like products from other brands (Hartz for example). The Dura Chews are especially great for our hard chewers and they last forever! I love all of the dimples on their chews too, they're great for keeping our dogs' teeth clean. The vet is always impressed when they check their teeth.

This is not designed for dogs who are chewers. I gave this to my adult dog thinking she could play with it and be entertained for a little while. She had it ripped up and spread around the room in about 10 seconds. I would maybe recommend this for puppies to have something softer and gentle on their little teeth and gums. It also makes a bot of a mess once it starts coming apart so I suggest using outside or where it can be contained. Little high of a price point for the value I got out of it
