Which nanomaterials have different crystal forms
In recent years, the application of nanomaterials has received
increasing attention. Nanomaterials have a larger specific surface area
and submicron size, giving them chemical and physical properties that
differ from macroscopic substances. The crystal structure of
nanomaterials has a significant impact on their properties.
Nanomaterials with different crystal forms have certain advantages in
their respective application fields.
Dongguan SAT NANO is a professional company that provides nanomaterials,
with years of technical research and market experience. We provide
customers with high-quality nanomaterials and different crystal forms to
help them meet their innovative needs.
Next, let's take a look at several common nanomaterials and their different crystal forms.
Titanium dioxide is a widely used nanomaterial that can be used in fields such as solar cells, catalysts, self-cleaning coatings, etc. The crystal forms of titanium dioxide include rutile phase, rutile phase, and rutile rutile phase. The rutile phase titanium dioxide has a high specific surface area and good optical properties, making it suitable for preparing dye sensitized solar cells. The rutile phase of titanium dioxide has good catalytic activity and is widely used in the field of catalysts.
2. Carbon nanotubes
Carbon nanotubes are nanomaterials with special mechanical, electrical, and thermal properties. The crystal form of carbon nanotubes has various forms such as single walled, multi walled, and corolla. Among them, single-walled carbon nanotubes are a unique hollow pipeline structure with good conductivity and thermal conductivity, making them very suitable for making battery electrode materials and conductive composite materials.
3. Nano gold particles
Nano gold particles are a common metal nanomaterial that can be applied in fields such as biomedicine and printing. The crystal forms of gold nanoparticles include hexagonal and face centered cubic crystal systems. Hexagonal crystal based gold nanoparticles can be used as carriers for anti-cancer drugs, while face centered cubic crystal based gold nanoparticles can be applied to the production of printed products.
