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.

What are functionalized carbon nanotubes?
Functionalized carbon nanotubes (f-CNTs) are carbon nanotubes that have been chemically modified by attaching functional groups to their surface. This is done to improve their solubility, biocompatibility, and ability to interact with other materials.
Why functionalize carbon nanotubes?
The key benefits of functionalizing CNTs include:
·Improved dispersion and solubility in solvents and polymer matrices
·Enhanced interfacial interactions with other materials like polymers
·Better biocompatibility for biomedical applications
·Ability to attach therapeutic agents or targeting moieties for drug delivery
What are the methods for functionalizing CNTs?
There are two main approaches:
·Covalent functionalization: Forming covalent bonds between functional groups and the CNT surface, often by oxidation reactions
·Non-covalent functionalization: Using van der Waals or π-π stacking interactions to attach functional molecules to the CNT sidewalls without disrupting the sp2 structure
What functional groups are commonly used?
Some widely used functional groups include carboxyl (-COOH), hydroxyl (-OH), amine (-NH2), and others like polymers, biomolecules, fluorescent probes etc. based on the desired application.
What are the applications of f-CNTs?
Functionalized CNTs find applications in various fields like:
·Polymer composites with improved mechanical/electrical properties
·Biosensors and biomedical imaging
·Targeted drug/gene delivery vehicles
·Water purification membranes
·Energy storage devices like supercapacitors
Are there any toxicity concerns?
While functionalization can improve biocompatibility, the toxicity of f-CNTs depends on factors like functionalization degree, functional groups, exposure route etc. Careful evaluation of their potential toxicity is required before biomedical use.
