THE FORMATION METHOD OF FLOWER-LIKE SILVER NANO MATERIAL BY USING PULSED PROTON BEAM

摘要

invention is a silver salt of an alcohol aqueous solution to the prepared aqueous phase and the proton beam irradiation pulse to the step of is a flower shape including relates to a process for the production of nanomaterials. The silver salt is silver nitrate Here, the acid is perchloric acid, and sulfuric acid is at least one may be a selected from the group consisting of alcohol may be a mixture of polyvinyl alcohol and a secondary or tertiary alcohol, in particular , secondary or tertiary alcohol is an alcohol of a carbon number of 3-10, and preferably from isopropyl alcohol. Polyvinyl alcohol, the mixing ratio of the secondary or tertiary alcohol in a weight ratio of 10: 1 to 1: 1 and the number of days, the concentration of the silver salt to the aqueous solution of alcohol may be from 1 mM to 100 mM Irradiating the proton beam pulses, the peak current is 1 to 20 mA, and a pulse width is 50 to 1 ms, repetition rate of the proton beam is a 0.1 to 60 Hz, 1 MeV to 100 MeV of energy beam having an acceleration can be to examine the proton beam irradiation step for irradiating a number of proton beam pulse may be from 1 to 100 hoeil, by adjusting the number of irradiation of a proton beam pulse irradiating the flower shape is easy to shape of nanomaterials it can be controlled. ;
