摘要

PURPOSE: A method for manufacturing lower-shaped silver nanomaterials based on the irradiation of proton beam pulse is provided to easily adjust the shape of the silver nanomaterials by adjusting the irradiation number of the proton beam pulse.;CONSTITUTION: A method for manufacturing lower-shaped silver nanomaterials based on the irradiation of proton beam pulse includes the following: The alcohol aqueous solution of silver salt is prepared. Proton beam pulse is irradiated to the aqueous solution. The alcohol is the mixture of polyvinyl alcohol and binary or tertiary alcohol. The mixed ratio of the polyvinyl alcohol and the binary or tertiary alcohol is between 10:1 and 1:1. The concentration of the silver salt with respect to the aqueous solution is between 1 and 100mM. The peak current of the irradiation is between 1 and 20mA. The pulse width of the proton beam is between 50um and 1ms. The repetition rate of the proton beam is between 0.1 and 60Hz.;COPYRIGHT KIPO 2012
