Fullerene Powder has excellent redox properties, high electron affinity, small recombination energy, and excellent mobility. The functionalized fullerene derivatives can not only maintain the properties of Fullerene Powder, but also realize solution processability and control of physical and chemical properties. By introducing different functional groups on fullerenes, the solubility, energy level, surface energy, orientation in the solid state, and intermolecular forces of fullerene derivatives can be further adjusted to achieve the fullerene derivatives. Multifunctionality makes Fullerene Powder an ideal acceptor material in solar cell applications. Such as PCBM, NCBA, ICMA, etc. In addition, its application in different fields including optical converters and field effect transistors can be expanded.
The electric sensor prepared by the electrode modified by Fullerene Powder has the advantages of reproducibility, simple production process, effective increase of the active surface area of the electrode, support of nanoparticles and compatibility with other materials compared with the electric sensor of traditional materials.
Fullerene Powder could serve as the basis for a new class of catalyst materials. Smalley proposed that some metal atoms known to have catalytic properties, such as platinum (pt) and palladium (pd), can be added to the central space of fullerene molecules to make a new class of catalysts. In this catalyst, The catalytic atoms are protected by carbon cages.
C60 has a special spherical shape, which is the roundest molecule among all molecules; in addition, the structure of C60 makes it have special stability. At the molecular level, a single C60 molecule is extremely hard, which makes C60 fullerene have excellent self-lubricating properties, and has the potential to become the core material of “molecular ball (shaft)” advanced lubricants. Improve the friction performance of fluid lubrication system and solid lubrication system (solid film, carbon-based, polymer-based, metal-based, ceramic-based lubrication system), which can reduce the friction coefficient of the system, reduce the wear rate, and increase the hardness, thereby optimizing Friction properties.
CVD diamond film
Another potential application of Fullerene Powders is that they can play an important role as uniform nucleation sites for diamond film growth. One of the unique properties of Fullerene Powder materials is that they sublimate at relatively low temperatures. For C60, the sublimation point is about 600 °C, which makes fullerene gas deposition coverage on irregularly shaped surfaces relatively easy to achieve.
In addition, since Fullerene Powder is easily soluble in polar organic molecular solvents such as benzene and toluene, complex surfaces can be directly immersed in the prepared solution at room temperature, and a layer of Fullerene Powder molecular film will be left after the solvent evaporates . Diamond films have many applications in the military, such as as an impact-resistant coating on the surface of armored vehicles, for making optical (X-ray, particle beam) windows, semiconductor wafers, high-hardness surface gears, diamond-fiber composite materials, and high-temperature And radiation-proof electronic devices, etc.
The molecular structure of C60 is quite special, and it can be used as a more effective hydrogen absorbing material than metals and metal alloys. At present, Chinese and American scientists have discovered a new type of material “C60+Ca” with the ability to store hydrogen, which can not only store hydrogen, but also store oxygen. What’s more, the pressure of gas stored in high-pressure cylinders is 63.9×10 Pa, while the pressure of oxygen stored in 60C is only 52.3×10 Pa. Using C60 to store a large amount of oxygen under low pressure conditions is of great importance for military, medical and even commercial development. the role of .
American scientist Bell discovered the superconductivity of Fullerene Powder, that is, K3C60 with a superconducting critical temperature of 18K was obtained after doping active metal potassium in C60. The discovery of doped C60 superconductor is another major achievement in the field of superconductivity. This superconductor has a relatively high critical temperature. The critical temperature of doped C60 superconductors is not only much higher than that of all organic molecular superconductors, but also much higher than that of previously discovered metal and alloy superconductors, only higher than the hot oxide ceramic superconductors. Low.
The biggest advantage of Fullerene Powder superconductors is that this compound is easy to process into various shapes required; at the same time, because they are three-dimensional molecular superconductors and are isotropic, current can flow equally in all directions. At the same time, the Fullerene Powder compound superconductor also has a higher critical magnetic field and critical current density. Theoretical analysis and some experimental results show that the superconducting critical temperature may be greatly increased in larger fullerene molecular doped compounds. Good properties and potentially high critical temperature create conditions for the application of Fullerene Powder superconductors.
Fullerene C60 has the functions of scavenging active oxygen free radicals, activating skin cells, and preventing aging. McEwen et al. first proposed the concept of “vitamin C60 free radical sponge”. Fullerene C60 molecules can scavenge free radicals like a sponge , strong absorption and large capacity. Japanese scientists Takada and other research found that fullerene C60 can quickly capture free radical molecules. Since the 21st century, fullerenes have been used as raw materials for cosmetics. They have excellent value in anti-wrinkle, whitening and anti-aging, and have become high-profile cutting-edge beauty ingredients. Many high-end skin care brands contain fullerenes.
Fullerene Powder is an important member of carbon nanomaterials. Its special molecular structure determines its more special physical and chemical properties, its good biocompatibility, reactive active surface and its large ratio as nanoparticles. The surface area and small size effect make it widely used in the research of drug carriers in the field of biomedicine.
As a drug delivery carrier, fullerenes have unique advantages in assisting the absorption and distribution of antitumor drugs in the body. First of all, as a kind of carbon nanomaterials, fullerenes are non-polar molecules with lipophilicity, and can directly penetrate tissue cell membranes in vivo; and, like other nanomaterials, they can be assembled and modified into nanoparticles by enhancing The enhanced permeability and retention effect of the drug preferentially accumulates in the tumor tissue. Secondly, the carbon cage structure of Fullerene Powder makes it have a large specific surface area, and different groups can be attached to its surface at the same time. After functional modification, it can not only improve its biocompatibility, but also enhance its targeting in vivo It can realize the sustained release and controlled release of drugs, and it can also have a larger loading capacity as a drug carrier.
