Product Overview

The CVD method for preparing carbon nanotubes is widely used because of its advantages such as mature method and high yield. However, the preparation of carbon nanotubes by CVD method often requires the introduction of a catalyst, and the nanotubes grow gradually along the radial and axial directions with the catalyst particle as the center. The difficulty of removing the catalyst has become an important factor restricting the purity of the carbon tube, which will limit the application of the carbon tube to a certain extent. Graphitized carbon tube is the ordinary carbon tube in the inert atmosphere of high temperature treatment, can effectively remove the catalyst and other impurities, effectively improve the purity of the carbon tube, reduce defects, effectively improve its microstructure, in order to obtain good electrical, thermal, mechanical and other properties. The higher the degree of graphitization, the better the crystallinity, thermal stability and electrical conductivity of the carbon nanotubes are generally better.

Product characteristics


High purity: Most of the metal impurities are removed under high temperature treatment of the carbon tube.

It has good flexibility and elasticity and can withstand large deformation without breaking. For example, in some micro-mechanical parts, complex movements can be achieved using their flexibility.

Electrical properties:

It has good electrical conductivity, and the electrical conductivity can be close to copper.

Exhibit unique quantum conductivity properties. For example, in nanoelectronic devices, their conductance characteristics contribute to precise current control.

Thermal properties:

The thermal conductivity is very high and can effectively conduct heat.

Good thermal stability, can still maintain the stability of structure and performance in high temperature environment. This makes it a potential application in highly efficient cooling materials, such as the cooling components of high-power electronic devices.

Chemical properties:

High chemical stability, not easy to react in most chemical environments.

The surface can be chemically modified to meet different application requirements. For example, it can be better dispersed in certain solvents or substrates through chemical modifications.

Optical properties:

It has unique optical absorption and emission characteristics in the near infrared and visible regions.

It can be used to make optical sensors and light-emitting devices.


Application Fields

Battery electrode: graphitized carbon nanotubes can be used as a conductive agent for lithium batteries to improve the conductivity and cycle life of the battery.

Composite materials: By adding graphitized carbon nanotubes to substrates such as polymers, metals or ceramics, composites with high strength, high electrical conductivity and high thermal conductivity can be prepared.

Electronic devices: Integrated circuits based on semiconductor graphitized carbon nanotubes and display backplane drivers are being developed.

Sensor parts: graphitized carbon nanotubes have the characteristics of high sensitivity and fast response, and can be used to prepare gas sensors, biosensors, etc.

Electric heater parts: Using the good electrical conductivity and electric heating conversion performance of graphitized carbon nanotubes, efficient electric heater parts can be prepared.

Defective toy and inconsistent quality.
Size: X-Large, Color: Raccoon, Size: X-Large, Color: Raccoon
My initial review was 5 stars based on my experience with a previous order (blue raccoon) and the fact my puppy was immediately interested in it. However, I did not give it to her to play with until this past Friday (May 21, 2026) because she had the first one I bought. In a matter of 2 days the seam on the back and at the base of the head unraveled and all of the stuffing was scattered all over the room. I thought I’d found some good, high quality, toys for her but apparently this one was defective because the first one had had a lot of use and I’d still in decent shape. This is too much money to pay for a dog toy that only lasts a day or two so be advised they aren’t all good.

Bigger, louder, crinklier, softer, than expected!
Size: X-Large, Color: Rabbit
My dog was gifted a collection of used toys and he really likes a very long stuffed pig which, unfortunately, another dog that is a destructive chewer, totally destroyed. I decided to break down and buy him another long stuffed toy today and since he's always blissfully watching rabbits in the yard and neighborhood I chose the rabbit version. This thing is huge which is great for him- he's 62 lbs and 7 months old and only half grown. He loves it, it has multiple LOUD squeakers, lots of crinkly spots, and fun ears/legs to grab hold off. He's a big fan and it's made with K9 Tuff Guard which LASTS. Super soft and easy to wash. Update after 2 months- easy to wash and looks new after a washing. very durable so far, standing up to indoor and outdoor use. He is not a destructive chewer but whips them around, tramples on them, steps on them while running top speed and chomps on the annoying squeaker for hours. one squeaker has a hole and its tune is now slightly muted (thank god)

Puppy loves! Supposed to be part of a set though??
Style: Coconut Tree
Bought this simply because we named our puppy Coco and was on a roll ordering her toys… she ended up absolutely LOVING this tiny palm tree!! Maybe because of the size and she was able to really handle it, she takes it everywhere with her and loves the squeaker. HOWEVER, the item is a lot smaller than I expected when ordering for almost $10 and the plastic packaging it came in says “not intended for individual sale, part of a pack” so I would not purchase from this seller again. I will maybe try to find this included with the intended set of toys.

It IS very small
Style: Coco-Nut, Style: Coco-Nut
I did not read the description and just saw 7.5 inches which usually is a pretty good sized toy BUT this is 7.5 inches circumference. They did state this in the product description but not a usual measurement so I missed it. Just wanted others to know what they are getting for $9.

Tiny Cheap Toy
Style: Coconut Tree, Style: Coconut Tree
It is way smaller than advertised and is maybe worth $0.50 cents. Only appropriate for toy breeds who do NOT chew.
