X-ray radiolysis-based three dimensional additive manufacturing process

To achieve the three dimensional additive manufacturing process, we investigated X-ray radiolysis-induced chemical reaction of Cu(CH3COO)2 solution. Here, we demonstrated synthesis and immobilization of cupric oxide particles onto a silicon or aluminium substrate using X-ray radiolysis directly from a liquid solution. The X-ray radiolysis of Cu(CH3COO)2 solutions was observed to produce curious shaped microstructures consisting of cupric oxide (CuO, Cu2O, Cu4O3) particles and Cu particles. The sizes of the particles depended on the additive type of alcohol. The results indicate that there are several routes and reaction processes for these particles and aggregation to be synthesized. In addition, we demonstrated the synthesis of these particles using X-ray radiolysis cell combined with a solution flow system. The developed technique of X-ray radiolysis enables us to achieve the rapid and easy synthesis of higher-order structures consisting of cupric oxide and copper particles onto the desired area.
