Microwave irradiation technique is successfully used to synthesize the copper coated MWCNTS in a one-pot reaction with and without surfactant. Since the graphite carbon absorbs the (in 2min 1100oC) maximum microwave radiation had led to the quick and uniform copper nanoparticles coating on MWCNTS. The advantage of this method is particles sizes and extent of coating can be controlled by varying the concentration of precursor and surfactant. Besides this the method is also can be used to synthesize or coating of other transition metals from their metals acetates. The method can be scalable for bulk production, which is the key element in the usage of multifunctional nanostructural materials for structural composite applications.
