Abstract

The invention discloses a preparation method and a preparation device for a negative-curvature hollow-core terahertz polymer waveguide. The length of the prepared waveguide can be infinitely long in theory, which is beneficial to the stability of the quality of the terahertz waveguide device and mass production. The large-scale application of terahertz waveguide communication systems provides low-cost high-quality thin-walled waveguide devices. The main implementation steps of the method include: 1. Fully drying the granular optical polymer raw material; 2. Sending the dried granular material into a vertical single-screw extruder, and stirring in the vertical single-screw extruder 1. Fully heated and plasticized under the push to form a fluid material; 3. Forming and synchronous stretching of the waveguide prefabricated structure; 4. Winding and winding the negative curvature hollow-core terahertz polymer waveguide.

Description

technical field [0001] The invention discloses a preparation method of a terahertz polymer microstructure waveguide, in particular to a preparation method and a preparation device of a negative-curvature hollow-core terahertz polymer waveguide. Background technique [0002] The existing terahertz polymer microstructure waveguide is prepared by a two-step method of drawing in a drawing tower after the preparation of a large-scale preformed rod. According to the different preparation methods of the preform, it can be divided into the stacking-stretching method and the extrusion-stretching two-step method. The method of manufacturing stacked preforms is mainly to use large-diameter polymer pipes to nest together several or hundreds of small-diameter pipes arranged in a certain order; the method of manufacturing extruded preforms is mainly to use extrusion The machine is connected with the preform rod mold, and the preform rod is made in the mold by thermoplastic extrusion mold...
