Preparation method of transparent ceramic optical fiber
The invention relates to a preparation method of a transparent ceramic optical fiber. The method comprises the following steps: adding a dispersing agent, an organic monomer and a cross-linking agent into deionized water to prepare a premixed solution; adding ceramic powder into the premixed solution, and carrying out ball milling to prepare a water-based material body; filtering, sequentially adding single-walled carbon nanotubes, a binder, a plasticizer and a surfactant into the material body, and uniformly stirring and mixing; vacuumizing, stirring and degassing, adding an initiator, and uniformly stirring and mixing; extruding a continuous ceramic optical fiber wet blank through an extrusion hole, drying the optical fiber wet blank, calcining and discharging glue, and cooling to room temperature along with the furnace; after vacuum sintering, cooling to room temperature along with a furnace, and annealing in an air atmosphere to obtain a transparent ceramic optical fiber primary product; and polishing the surface and the end face of the transparent ceramic optical fiber primary product by using a femtosecond laser vortex beam with orbital angular momentum of -5 to +5 to obtain a ceramic optical fiber finished product. According to the method, continuous long fibers can be prepared, the uniformity, compactness and mechanical property of the optical fibers can be improved, and large-area processing of fine structures is achieved.
一种透明陶瓷光纤的制备方法，该方法包括如下步骤：将分散剂、有机单体、交联剂加入到去离子水中配成预混液；向预混液中加入陶瓷粉体，球磨配成水基料体；过滤，向料体中依次加入单壁碳纳米管、粘结剂、增塑剂和表面活性剂，搅拌混合均匀；抽真空搅拌除气后加入引发剂，搅拌混合均匀；通过挤出孔挤出连续陶瓷光纤湿坯，将光纤湿坯干燥后进行煅烧排胶，随炉降至室温；真空烧结后随炉降至室温，再在空气气氛下退火得到透明陶瓷光纤初品；采用轨道角动量为‑5～+5的飞秒激光涡旋光束对透明陶瓷光纤初品表面和端面进行抛光处理，得到陶瓷光纤成品。该方法能制备出连续性长纤维，可提高光纤的均匀性、致密性和力学性能，实现精细结构大面积的加工。
