The invention relates to a method for 3D printing a high-intensity continuous streamer photocatalytic system. The catalyst is mounted on the surface of a high-intensity 3D printing structure, and stable internal light is obtained through a point light source, the light energy utilization efficiency is greatly improved, and the breakthrough of high-performance photocatalysis is achieved. Apply restrictions. As a functional material, optical fiber transmits light, and at the same time, it has the effect of strengthening the composite structure. As a structural material, polymer has good strength and toughness, and at the same time constrains the three-dimensional molding of optical fiber, the two have a synergistic reinforcement effect. Compared with the pure polymer carrier without optical fiber reinforcement, the compressive strength is increased from 21.27±3.19MPa to 60.84±4.32MPa, and the mechanical properties are improved by nearly three times. The invention realizes a continuous streamer photocatalytic system suitable for 3D printing technology, adjustable microstructure, simple light source, high structural strength, and can significantly improve catalyst efficiency and stability. |
