Graphene on PET substrates combine excellent electrical conductivity, optical transparency, and mechanical flexibility, making them ideal for flexible electronics, transparent conductive films, optoelectronics, infrared devices, sensors, and advanced semiconductor research.
Graphene on PET substrates are widely used in flexible electronics, transparent conductive films, infrared devices, sensors, photonics research, and optoelectronic applications because they combine electrical conductivity with optical transparency and mechanical flexibility.
Researchers often request graphene on PET samples with specific sheet resistance, substrate size, optical transmission, and conductivity characteristics depending on the intended device application.
A researcher asked:
Can you provide the sheet resistance of graphene on PET samples, especially for large-area substrates?
2 questions:
a) Is 1 cm × 1 cm the largest available size? Can you provide 5 cm × 5 cm samples?
b) Is it possible to achieve lower sheet resistance values around 100 Ohm/sq maximum?
UniversityWafer, Inc. replied:
The typical sheet resistance for monolayer graphene on PET substrates is approximately 580 ± 50 Ohms/sq for 1 cm × 1 cm samples.

Common graphene on PET research requests include:
Graphene on PET is a flexible, transparent conductive material used in advanced research involving flexible electronics, sensors, transparent conductive films, optoelectronics, touch displays, solar cells, and infrared devices. PET provides a lightweight flexible polymer substrate, while graphene adds electrical conductivity, optical transparency, and mechanical strength.
Graphene is a single layer of carbon atoms arranged in a two-dimensional honeycomb structure. Because it is extremely thin, conductive, transparent, and flexible, graphene is often studied as an alternative to traditional transparent conductive materials such as ITO glass wafers.
Sheet resistance is one of the most important specifications for graphene on PET samples. It describes how easily electrical current moves across the surface of the graphene film. Lower sheet resistance is usually preferred for transparent conductive films, flexible circuits, sensors, and optoelectronic devices.
Graphene on PET samples are commonly used when researchers need a flexible conductive surface for testing electrical performance, transparency, bending durability, and device integration.
Graphene on PET substrates are used in many research and development applications because they combine conductivity with flexibility. Common applications include:
Researchers may also use graphene substrates, silicon wafers, and thin film materials for related semiconductor and optoelectronic experiments.
Graphene is attractive for transparent conductive film research because it offers a unique combination of high carrier mobility, optical transparency, flexibility, and chemical stability. These properties make it useful for devices that require both light transmission and electrical conductivity.
