Graphene few-layer film, applications in energy generation and storage

High quality and available online for fast, secure dispatch


Graphene few-layer film consists of ultra-thin layers of carbon atoms that are arranged in a hexagonal honeycomb lattice. Graphene film produced via chemical vapour deposition (CVD) is polycrystalline in nature, with multiple small graphene domains growing to merge into a continuous film.

Compared to single-layer graphene, few-layer graphene has the potential to be developed into hybrid materials or heterostructures - via intercalation of different substances into its layered structure.

Applications in photovoltaic devices/ batteries, sensors and flexible electronics, and photodetectors

Applications of Graphene Few-Layer Film

With a unique combination of novel electronic, optical, and mechanical properties, graphene-based nanomaterials find applications in energy generation and storage. For example, they have applications in photovoltaic devices and batteries, sensors and flexible electronics, photodetectors, and biomedical applications (e.g. drug delivery, bio-imaging, and tissue engineering).

Synthesis

High quality few-layer graphene films were first grown directly on copper foil via the chemical vapour deposition (CVD) method. The films were later transferred to the desired substrates via the wet chemical graphene-transfer process.

Usage

Monolayer graphene films are ready to use in various research purposes, such as microscopic analysis, photoluminescence and Raman spectroscopy studies. Graphene few-layer films can also be transferred to other substrates.
