This invention discloses a 3D-printed liquid crystal elastomer (LCE) actuator and its electrothermal actuation method, belonging to the field of smart materials technology. Addressing the problems of complex alignment processes, difficulty in balancing printability and actuation performance, and limitations in three-dimensional structures inherent in traditional LCE processes, this invention utilizes material-structure co-design to directly induce liquid crystal alignment using the shear force of the 3D printing nozzle and achieves local alignment programming. By controlling the ratio of furan to phenylethylamine to construct a cross-linked network containing dynamic Diels-Alder bonds, high-temperature decrosslinking 3D printing and structural reconfigurability are achieved. Optimized printing parameters combined with conformal printing are used to fabricate a large-deformation three-dimensional LCE actuator. Electrothermal actuation is achieved using Joule heating with a serpentine resistance wire. The actuator prepared by this invention exhibits fast phase change response, large actuation deformation, and can be integrated into a single unit, making it suitable for flexible intelligent equipment and soft robots.

This invention relates to the field of negative pressure automatic water discharge device technology, and discloses a mine negative pressure automatic water discharge device with anti-backflow function. The device includes a negative pressure automatic water discharge device, an upper cylinder cover fixedly installed at the upper end, an inlet pipe fixedly installed on one side of the device, and an outlet pipe fixedly installed at the lower end.
