Nano-diamond is a new type of carbon nanomaterial. At present, nano-diamonds on the market are generally prepared by explosive detonation method. Weakness, hard agglomeration, uneven particle size and other shortcomings. There is a new type of nanodiamond-single crystal flake nanodiamond, the specific characterization results are as follows:
The morphology of nano-diamond is flake-like, with good dispersion, and it is a single crystal structure.
The crystallinity of flaky nanodiamonds is much stronger than that of detonation nanodiamonds.
The surface of single-crystal flaky nanodiamonds is rich in functional groups, such as hydroxyl-OH, which is conducive to compounding with other materials. In addition, flaky nanodiamonds can be made with other functional groups through surface modification technology.
Single-crystal flake nanodiamonds are available as suspension and dry powder, and the color is off-white. The nano-diamond has excellent dispersibility and is easily dispersed in water.
1. Dispersion stability in water system
Nanodiamond concentration wt%=50%
2. Dispersion and spraying effect in water-based epoxy resin
The flake-shaped nano-diamond is uniformly dispersed in epoxy resin after stirring and has stable dispersion for a long time, and the coating is transparent after spraying on the iron base material.
3. Dispersion stability in oleoresin
The flaky nano-diamonds can be uniformly dispersed in the oleoresin after being stirred and remain stably dispersed for a long time. It can be seen through optical microscope observation that the flaky nano-diamonds are uniformly dispersed in the whole system.
4. Dispersion stability in ink
a: pure ink
b: 0.1%ND
The flake nanodiamonds can be uniformly dispersed into the ink and remain stable for a long time.
