Nicholas Pugno of the University of Trento and his team collected 15 spiders, which sprayed 5 of them a mixture of graphene and water, and 10 of them used carbon nanotubes and water. The mixture was sprayed and used as a comparison group to observe the effects of the two materials. If you are concerned that the nanomaterial coating will threaten the life of the spider, you are right - four of the spiders will die immediately. Among the surviving spiders, several of the spit silks were of poor quality, while others briefly spit out the silk containing the spray material after a short adjustment. These cobwebs, which are infused with carbon, are super tough, and the silk spit from a spider sprayed with carbon nanotubes is stronger than the current silkworm toughness record holder. 3.5 times. In theory, when a spider is silking, it will find suitable materials (whether eaten or absorbed) from the environment, and people can control the texture of the spider silk by controlling the external environment. Researchers don't know which form of graphene and carbon nanotubes are incorporated into the spider silk, but the carbon-containing spider silk is actually produced from the spider's belly. One possibility is that the carbon is wrapped directly on the outside of the wire, but Pugno believes that it is not enough to enhance the toughness of the wire. Instead, he firmly believes that spiders sweep the material in the environment and incorporate it into the spider silk during the silking process. Limited experience means that follow-up research and replication activities are based on well-defined mechanisms. Researchers believe that this super-strong spider silk can only be produced in small batches, and the specific use is still unknown, but "this method can be extended to other animals and plants, which can lead to a new class of biomimetic materials. application".
