▎ 摘　　要

NOVELTY - The macroscopic laser traction method in a thin gas involves: placing a macroscale graphene aerogel/silica bilayer in a rarefied gas; irradiating the silica layer using laser beams to obtain traction force; and subjecting the graphene aerogel/silica bilayer structure and the related objects to macroscale laser traction in the rarefied gas. The rarefied gas comprises air, argon and nitrogen. The silica layer is a transparent and thermally insulating thin layer of quartz, ordinary glass or aluminum oxide. The graphene aerogel/silica bilayer structureis directly pulled by the laser beam or other payloads are added to the structure to further carry out laser traction of complex structures and loads. The payloads are PET plastic sheets, micro-nano detectors, and light-weight structures of micro-nano sensors. USE - Method for performing macroscopic laser traction in the rarefied gas for a micro-nano-scale object is useful in the fields of commerce, scientific research, information and military, material processing and measurement control, and medical applications (claimed). ADVANTAGE - The method overcomes the micro-scale limitation of the object to be pulled by the existing optical pulling technology, can realize the laser pulling at the macro scale, and can realize the graphene aerogel/silica bilayer without any fuel. The traction force is far greater than the light pressure (radiation pressure). The whole process is simple and efficient, green and environmentally friendly, and has broad application prospects. The method realizes the laser traction movement of the macroscopic pendulum device. The method uses the optical lever method to measure the traction force, and when the laser power is only 10 mW, the traction force is up to 1 µN. If a higher laser power is used, a greater traction above mN can be generated without an upper limit. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a macroscopic laser traction device. DESCRIPTION OF DRAWING(S) - The drawing shows a flow chart of a macroscopic laser traction method in rarefied gas. (Drawing includes non-English language text).
