Abstract
Functionalized detonation nanodiamond particulates of the formula: wherein Ar is selected from the group consisting of: wherein R is selected from the group consisting of H, H3C—(CH2)n— and wherein n has a value of 0-10. Also provided is a process for functionalizing detonation nanodiamonds particulates.
Claims2
Functionalized detonation nanodiamonds particulates of the formula:
- wherein Ar is selected from the group consisting of:
- wherein R is selected from the group consisting of H, H3C—(CH2)n— and
- wherein n has a value of 0-10.
A process for preparing functionalized detonation nanodiamonds particulates of the formula:
- wherein Ar is selected from the group consisting of:
- wherein R is selected from the group consisting of H, H3C—(CH2)n— and
- wherein n has a value of 0-10, which comprises the steps of (a) combining an acid Ar—COOH, wherein Ar is as defined above, detonation nanodiamonds particulates, and 83% PPA, (b) stirring this mixture at about 130° C. for about 3 hours, (c) adding additional P2O5, (d) continuing to heat the mixture with stirring for about 24-60 hours, and (e) recovering the reaction product.
