3results about How to "Address mechanical properties" patented technology

The application belongs to the technical field of lighting lamps, and particularly relates to a three-dimensional full-space wireless sliding table lamp with anti-dazzle and eye protection, which comprises a supporting frame, a lifting mechanism, a horizontal adjusting mechanism, a wireless sliding connecting assembly, a balance structure and a bidirectional light-emitting anti-dazzle assembly. A placing seat is fixedly connected to the bottom of the supporting frame, and a first sliding groove is formed in the vertical direction in the middle of the supporting frame. The lifting mechanism comprises an adjusting plate arranged at the end of a fixed cylinder, and a positioning rail is fixedly connected to the outer wall of the adjusting plate. The adjusting plate is clamped on the inner wall of the first sliding groove through the positioning rail. The LED upper lamp plate with a front inclination angle is arranged to effectively supplement the background light of the working environment. The bidirectional light-emitting mode significantly reduces the brightness ratio between the center of the working area and the surrounding environment, reduces the light-dark contrast, relieves the visual fatigue caused by frequent pupil adjustment of the human eye, and prevents myopia from the optical and physical aspects.

This invention belongs to the technical field of thermoelectric materials and functional polymer materials, specifically relating to a thermoelectric hydrogel based on the synergistic enhancement of zwitterionic and polar solvents, its method, and applications. The thermoelectric hydrogel is obtained by polymerizing a precursor solution to form a gel matrix, followed by immersion in an immersion solution to introduce a potassium ferrocyanide / potassium ferrocyanide redox couple. The precursor solution is prepared by mixing acrylamide, N-isopropylacrylamide, dimethyl sulfoxide, N,N-dimethylformamide, 1-ethyl-3-methylimidazolium tetrafluoroborate, the zwitterionic monomer [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfonic acid propyl)ammonium hydroxide, the crosslinking agent N,N'-methylenebisacrylamide, a photoinitiator, and deionized water. This invention prepares a thermoelectric hydrogel with high mechanical strength, high ductility, and a high Seebeck coefficient, and also exhibits good temperature resistance.
