General description

Indium tin oxide films are inherently brittle in nature. To overcome this, ITO is coated with transparent conductive polymers or nanomaterial.[1] Indium tin oxide coated polyethylene terephthalate (PET) film is optically transparent and electrically conductive.[2]The ITO coating is protected by a thin, transparent film, that can be easily peeled off.

Application

A radius of curvature of up to 75 mm will not damage the ITO coating.
Micro mechanical properties of ITO-PET were investigated. Electrical resistance of ITO-PET increases in case of degradation. [1] ITO-PET was used as an electrode in the electrochemical measurements in a study of biosensors composed of polymer brushes.[3] ITO microelectrodes were studied as an “electronic tongue” for analyte recognition.[2] The sheet resistance of ITO, after bending to a radius of 25 mm was investigated, for its use for flexible optical devices. [4] Giant unilamellar vesicle (GUVs) were produced on ITO coated glass slides by drying droplets of the FhuA proteoliposomes.[5]

Features and Benefits

The polyester film products comprise sputtered ITO, and exhibit transmittance and resistance characteristics similar to those of the glass substrates.

Articles

In this article, we demonstrate that bis-styrylbenzene derivatives show promising characteristics for very low lasing thresholds and discuss the design considerations for organic lasing molecules.

Organic photovoltaics (OPVs) represent a low-cost, lightweight, and scalable alternative to conventional solar cells. While significant progress has been made in the development of conventional bulk heterojunction cells, new approaches are required to achieve the performance and stability necessary to enable commercially successful OPVs.

A transparent conductive electrode (TCE) is an essential component of various optoelectronic devices such as solar cells, liquid-crystal displays (LCD), light-emitting diodes (LED), and touch screens.

  3. How are they made?

    1 answer
    1. Indium tin oxide is coated onto a polyethylene terephthalate surface. Specific details on manufacturing are withheld due to the proprietary nature of these processes.

      Helpful?

  4. Is the unit of resistivity, Ω/sq, referring to ohms per square meter or ohms per square inch?

    1 answer
    1. The unit of resistivity, Ω/sq, refers to a dimensionless square area of resistive material. It does not specify a specific unit of measurement such as ohms per square meter or ohms per square inch.

  5. Is this substrate stable at 5% hydrofluoric acid? My sample was synthesized surface of hydrofluoric acid, and i want to trasfer my sample onto this substrate.

    1 answer
    1. ITO coatings are soluble in mineral acids. A 5% concentration of hydrofluoric acid may be detrimental.

  6. What is the Thickness of the ITO layer

    1 answer
    1. The ITO coating thickness is 1300 Å as mentioned in the "Description" section under "Physical Properties".

      Helpful?

  7. How do I determine which side of this product has the Indium Tin Oxide (ITO) coating?

    1 answer
    1. The ITO side of the PET sheet has a blue protective film on it to prevent the ITO from scratching.  Once this film is removed, you can also determine the coated side by testing for ITO resistance using either a Multimeter or a Four Point Probe.

  8. Why isn't the Indium tin oxide (ITO) coated PET showing resistance?

    1 answer
    1. The Indium tin oxide (ITO) coated PET is protected by a thin, transparent film that can be easily peeled off.  This film will not show resistance, so it needs to be removed prior to testing the electrical properties.
