Abstract

A facile method to chemically grafting polyimides from diamonds was presented, and the hardness of the resulting diamond-based nanocomposites was evaluated by an ultra-microindentation technique. Critical challenges lied in achieving desirable interfacial adhesion between diamond particles and organic polymers to efficiently transfer the superior properties of diamond to polymer matrix in light weight and ultrasonic composites for use in hi-tech fields. A commercially available nanodiamond (ND) powder fabricated via detonation method was refluxed in thionyl chloride achieving acyl chloride groups on the ND surfaces and yielded acyl chloride-functionalized nanodiamonds (F-ND). Experimental investigation showed that the improvement to F-ND had helped to break the ND agglomerations during chemical functionalization and mixing, as well as anchored polyimide chains on diamond surface.
