Abstract

The invention provides a novel graphene thin film transferring method and a preparation method of a sensor and relates to the technical field of graphene. The novel graphene thin film transferring method comprises the following steps: covering melted paraffin wax on the surface of a graphene thin film which is formed on the surface of a growth substrate; after the paraffin wax is cured, removing the growth substrate to obtain a paraffin wax / graphene composite thin film; putting the paraffin wax / graphene composite thin film on the surface of a target substrate; heating the target substrate until the paraffin wax is fitted to the target substrate and removing the paraffin wax by utilizing a solvent. The method provided by the invention takes the paraffin wax as a novel transferring medium and is convenient to operate; and the graphene thin film can be basically transferred in a lossless manner. The preparation method of the sensor comprises the following steps: a channel electrode is manufactured on the surface of the graphene thin film prepared using the transferring method and a pattern of a touch sensor is formed by the graphene thin film; and an optical adhesive is fitted on the surface of the graphene thin film and then de-foaming treatment is carried out. By adopting the method provided by the invention, the obtained graphene thin film is complete, basically has no loss and has large area, and can be used for manufacturing the sensor.

Description

technical field

[0001] The invention relates to the technical field of graphene, and in particular to a method for transferring a novel graphene film and a method for preparing a sensor. Background technique

[0002] Graphene is a single atomic layer two-dimensional crystal with carbon atoms tightly packed in a hexagonal structure. Graphene has excellent properties such as extremely high carrier mobility, high light transmittance, and high strength. It has a huge potential in electronic devices. Value. In order to fabricate graphene electronic devices, large-scale graphene films with excellent electrical properties must first be fabricated and transferred to a suitable target substrate. The transfer technology of graphene film is the key factor restricting the development of graphene film.

[0003] At present, the transfer of graphene film is mainly through PMMA method, resin transfer method or thermal release tape method, but there are certain operational difficulties or ...
