The application discloses a lignin-based conductive eutectic gel and a preparation method and application thereof, and belongs to the technical field of intelligent soft materials.The lignin-based conductive eutectic gel comprises the following components in proportion by weight: 20-50 parts of polymerizable monomers, 0.01-0.2 parts of a crosslinking agent, 0.01-0.15 parts of sodium lignosulfonate, 3-6 parts of modified keratin, 0.1-1 parts of an initiator, 50-90 parts of a deep eutectic solvent and 50-100 parts of water; the polymerizable monomers are acrylic acid and [2-(methacryloyloxy)ethyl]dimethyl-(3-sulfopropyl)ammonium hydroxide; and the modified keratin is polyethylene glycol-based double-end crosslinking monomers and disulfide di(p-phenylene)di(2-methyl acrylate) grafted modified keratin.The lignin-based conductive eutectic gel has excellent strain sensing performance, can be used for monitoring the movement of different parts of a human body and personal health, and has excellent adhesion performance and can be stably combined with fitness equipment.

The application discloses a plastic embedding agent Big Cut resin, which is composed of a crosslinking agent and a non-reactive liquid auxiliary agent in a mass ratio of 3:7 to 7:3. The application further discloses a preparation method of the plastic embedding agent, which comprises the steps of mixing the crosslinking agent and the non-reactive liquid auxiliary agent in the mass percentage to obtain a mixture, and adding an initiator into the mixture to obtain the Big Cut resin. The application further discloses a plastic embedding method suitable for thick cutting of a large-volume sample, which embeds a biological tissue sample by using the Big Cut resin. The embedding method can realize uniform and stable polymerization of the large-volume resin, improve the cutting performance of the sample after embedding, meet the thick cutting requirement of an fMOST system, has the advantages of transparent depth imaging and adjustable refractive index, and realizes high-throughput imaging.
