Abstract
Bad dispersibility is a major cause that hinders the application of nanodiamond (ND) severely. In this paper nanodiamond was covalently functionalized with 1, 3-propanediamine to obtain a novel derivative (ND-NH2). FTIR results showed that the 1, 3-propanediamine molecules were covalently attached to the nanodiamonds through amide linkages. Content of the nanodiamond in the ND-NH2 is about 29.97wt%. The ND-NH2 dissolves not only in inorganic or organic acidic aqueous solution, but also organic solvents such as acetone, CH2Cl2, NMP, DMF, DMAc and DMSO. Laser Granularity and TEM results further indicated the dispersibility of the nanodiamond was much improved: the average granularity of the nanodiamond decreased from 3.301-0.166 μm by the modification of 1, 3-propanediamine. This might be a beneficial base for next study and application of nanodiamond in fields of complex electroplating and lubrication.
