X-ray Radiolysis-based Three Dimensional Additive Manufacturing Process

Abstract

To achieve the three dimensional additive manufacturing process, we investigated X-ray radiolysis-induced photochemical reaction of Cu(CH₃COO)₂ solution. Here, we demonstrated synthesis and immobilization of copper and copper oxide particles onto an aluminium substrate directly from the liquid solution. The particles are formed in the X-ray radiolysis of flowing aqueous solutions of Cu(CH₃COO)₂ which also contain methanol as ⋅OH scavenger. We found that the sizes and compositions of the particles depend on the flow rate of solution. The results indicate that there are several routes and reaction processes for these particles formation and their aggregation. Our study will shed light on understanding and providing a novel photochemical reaction route induced under the X-ray irradiation. The development of X-ray radiolysis-induced photochemical reaction process enables us to achieve the rapid and easy formation of higher-order nano/micro-scale structures consisting of composite materials.
