Product Overview

Multi-walled carbon nanotubes are made of multilayer coiled graphene sheets and maintain a fixed distance between the layers, forming a coaxial circular tube structure. The tube diameter is usually between 5 and 30nm, and the length can range from a few microns to dozens of microns. The specific size depends on the preparation method and conditions. The purity of industrial-grade MWCNTs can reach 95% or higher, ensuring their stability and reliability in applications. The main preparation method of industrial grade multi-walled carbon nanotubes is chemical vapor deposition (CVD) method. In the process of CVD, carbon source substances (such as methane, acetylene, etc.) are decomposed and deposited into tubular structures under the action of catalysts (such as iron, cobalt, nickel, and other transition metals at high temperature). Precise control of the diameter, length and structural properties of MWCNTs can be achieved by controlling reaction conditions and the use of specific catalysts.

Product Features

 

1)Mechanical properties: Industrial-grade multi-walled carbon nanotubes have extremely high strength and toughness and are considered the super fibers of the future. It is 100 times as strong as steel and weighs only 1 / 6 of steel, giving it great potential for composite enhancers.

2)Conductivity: Multi-walled carbon nanotubes have good electrical conductivity, even better than copper. This makes it widely used in electronic devices, conductive inks, sensors and other fields.

3)Thermal conductivity: multi-wall carbon nanotubes also have excellent thermal conductivity, their thermal conductivity is much higher than the general metals and alloys. This makes it have an important application value in the thermal interface materials, heat dissipation materials and other fields.

4)Chemical stability: Multi-walled carbon nanotubes have good chemical stability and can maintain their stability in a variety of harsh environments.


Application Fields

 

1)Electronic devices: Multi-wall carbon nanotubes can be used to manufacture high-performance conductive inks, sensors, flexible displays and other electronic devices. Their excellent electrical conductivity and mechanical properties enable these devices to have higher performance and longer service life.

2)Energy storage and conversion: Multi-walled carbon nanotubes can be used as electrode materials for lithium-ion batteries and supercapacitors to improve energy storage and power output capabilities. Its high specific surface area and excellent electrical conductivity make the electrode material have higher energy density and faster charge and discharge speed.

3)Composite materials: In composite materials, multi-wall carbon nanotubes as enhancers can significantly improve the mechanical properties and electrical conductivity of materials. They can be added to plastics, rubber, metal matrix, etc., to enhance the strength, stiffness, and thermal conductivity of the material.

4)Other fields: multi-walled carbon nanotubes can also be used as catalyst or catalyst carrier, hydrogen storage materials, thermal interface materials, etc., which has a wide application prospects in chemistry, energy, environmental protection and other fields.

Great choice for heavy chewers
Perfect for dogs that chew hard! Ours shred comparable toys at every turn, but this has held up beautifully. We’ve had it for a few months and it’s got minor wear and tear, but it is easy for them to play with, hardy, and worth every penny.

Durable, Fun, soft enough to not break teeth
Finally found a quality toy that our 75lb Black Mouth Cur hasn't destroyed in 5 minutes! In fact it's been a few months now. There are teeth marks, but she hasn't been able to take a chunk out of it yet. It even has some bounce to it when you toss it. And she finds it fun. Veterinary dentists recommend toys that are soft enough that you can leave a fingernail print in for toys that are less likely to break teeth, unlike bones and antlers. This is that toy! (My other dog broke both of her upper 3 rooted premolars on a Nylabone - healthy roots but the slab fracture exposed the pulp and had to be removed. Healthy roots are more difficult to remove. Dentists say those and antlers are money makers. 😭)

Great toy for big chewers!
Have only had 3 days but my boy has been trying to destroy it and it’s holding up really well! Normally his toys would have been destroyed in 24 hours or less, including Kong and other brands advertised as tough!

Durability is no joke!
Excellent product! Our GSD puppy chewed it for the past 10 months and she is a pretty strong chewer. Only now did she manage to get a couple small pieces off of it, and WoofBite was quick to provide our one-time replacement. Great customer service! Will purchase more of their products and highly recommend!

So far so good
Had this for almost a month and no chunks have been chewed off yet. I have a lab who prefers chewing over pulling or retrieving type toys. She's destroyed everything we've given her --sometimes within minutes. She loves Wubbas but she chews them to bits immediately. Other toys get chunks or small pieces chewed off and we wind up throwing them away. This has lasted well. Full disclosure, we only pull out toys at the end of the day for just a couple of hours, and we are within sight of her the whole time, that's why 4 stars. But so far to our surprise this has held up very well.
