▎ 摘　　要

NOVELTY - High power bidirectional driving bionic muscle fiber comprises the base fiber can be electrified to heat, and the guest material layer comprises a liquid crystal elastomer, the bionic muscle fiber is over-twisted to a spiral cylindrical structure. USE - The bionic muscle fiber is useful in preparing driver (claimed). ADVANTAGE - The bionic muscle fiber improves the mechanical performance of the liquid crystal elastomer, has large working ability and driving quantity, realizes fast response, has high frequency, has bidirectional driving characteristics circulating work, is greater than zero, has low complexity, solves the problem of complex and difficult to continuously prepare, and is good for development. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing biomimetic muscle fiber comprises providing matrix fiber and guest material precursor liquid, the matrix fiber can be electrified to heat, the guest material precursor liquid includes liquid crystal elastomer precursor, coating the precursor liquid of guest material on the surface of base fiber to form a liquid film, trigger reaction of the liquid film, forming a guest material layer on the surface of base fiber to obtain fiber precursor, over-twisting the fiber precursor, making the fiber precursor have a spiral cylindrical structure to obtain bionic muscle fiber.
