Introducing Shandong Dazhan Nano Materials Co., Ltd.'s Carbon Nanotube Powder

Our carbon nanotube powder is created using a nanoscale catalytic precursor that self-assembles into controllable layers through a high-temperature aliphatic hydrocarbon source. After reduction by hydrogen, the carbon nanotubes are formed through a CVD reaction.

With the utilization of a large-diameter fluidized bed reactor, we ensure better heat and mass transfer reaction effects, leading to stable batch production of kiloton-level carbon nanotube powder. This allows for efficient and reliable production on a large scale.

FAQ

What are high purity carbon nanotubes?
High purity carbon nanotubes refer to carbon nanotube samples that contain very low levels of impurities like residual catalyst particles, amorphous carbon, and other carbonaceous byproducts from the synthesis process123. Purities greater than 99% or even 99.9% are considered high purity.
Why is high purity important?
High purity is crucial for many applications of carbon nanotubes:
·Electronics/optoelectronics: Metallic impurities can degrade the semiconducting properties required for devices
·Composites: Impurities weaken the reinforcement effect and interfacial interactions with the matrix
·Energy storage: Impurities reduce the electrochemical performance in batteries and supercapacitors
·Biomedical: High purity is needed to minimize toxicity for in vivo applications
How are high purity CNTs produced?
Some common purification strategies include:
·Oxidation in air/acids to remove amorphous carbon
·Annealing under vacuum/inert gas to remove defects
·Polymer wrapping to separate semiconducting from metallic CNTs
·Density gradient ultracentrifugation
·Closed-loop recycling of raw materials for high yield
What challenges exist?
The main challenges in obtaining high purity CNTs include:
·Balancing purity and yield - harsh purification can damage CNT structure
·Removing stable metal oxide catalysts without functionalization
·Scalability and cost-effectiveness for industrial production
Are high purity CNTs commercially available?
Yes, Dazhan offer high purity (>99%) multi-walled and single-walled CNT products for research and commercial use5. Prices can range from $100 to over $1000 per gram depending on purity level and type.Overall, continuous research is focused on developing efficient, scalable, and economical methods to produce high purity CNTs for their numerous high-performance applications across various industries.
