(Summary description)Suspended self-transfer graphene is based on the soaked graphene, etching the copper substrate to obtain the graphene/protective layer film, and then transferring the graphene/protective layer film to the "suspended substrate". In this case Next, use the product simply by gently releasing it in deionized water to obtain a graphene/protective layer film that can be transferred directly to any substrate. After the graphene/protective layer film (the protective layer is generally selected from PMMA) is transferred to the target substrate, the protective layer (PMMA) can be removed by drying at low temperature and soaking in acetone. It is very convenient to use and can save a lot of energy for graphene researchers.

Information

Suspended self-transfer graphene is based on the soaked graphene, etching the copper substrate to obtain the graphene/protective layer film, and then transferring the graphene/protective layer film to the "suspended substrate". In this case Next, use the product simply by gently releasing it in deionized water to obtain a graphene/protective layer film that can be transferred directly to any substrate. After the graphene/protective layer film (the protective layer is generally selected from PMMA) is transferred to the target substrate, the protective layer (PMMA) can be removed by drying at low temperature and soaking in acetone. It is very convenient to use and can save a lot of energy for graphene researchers.

The method of self-transferring graphene in the air: take a dropper with pure water or deionized water, infiltrate the dust-free cloth substrate next to the graphene, and then slowly release it into the water, it will naturally float on the water surface.

The self-transferring graphene in the air is released into deionized water and then transferred to other substrates. Is the combination of graphene and substrate very strong: After the graphene is transferred to other substrates, the moisture is dried, and there is no air between the graphene and the substrate. It is very strong, and the binding force is mainly intermolecular force.

How to store suspended self-service graphene: For long-term storage, it must be stored in the fresh-keeping layer of the refrigerator to keep the packaging environment moist, or released into deionized water for sealed storage. It is best to use the product as soon as possible (about two weeks) after getting the product. After the packaging environment is dry, it is not conducive to the release and use of graphene. The water mist in the packaging bag is a normal phenomenon, which is generated by deionized water absorbed by the white dust-free cloth. The purpose is to maintain the humidity of the packaging environment and facilitate the user to remove the graphene from the substrate.

Can the suspended self-transfer graphene be cut again: if it can be cut, after the suspended self-transfer graphene is released into deionized water, it is transferred to the filter membrane for cutting, and then released into deionized water again after cutting, and then transferred to the target on the base.

Will the graphene transfer to the substrate fall off in a high temperature environment? Graphene will not fall off in a high temperature environment.
