General description

Indium tin oxide films are inherently brittle in nature. To overcome this, ITO is coated with transparent conductive polymers or nanomaterial. Indium tin oxide coated polyethylene terephthalate (PET) film is optically transparent and electrically conductive.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. ITO-PET was used as an electrode in the electrochemical measurements in a study of biosensors composed of polymer brushes. ITO microelectrodes were studied as an “electronic tongue” for analyte recognition. The sheet resistance of ITO, after bending to a radius of 25 mm was investigated, for its use for flexible optical devices. Giant unilamellar vesicle (GUVs) were produced on ITO coated glass slides by drying droplets of the FhuA proteoliposomes.

Features and Benefits

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

Physical properties

Thickness of ITO coating is 1300 Å

  4. What is the Department of Transportation shipping information for this product?

    Transportation information can be found in Section 14 of the product's (M)SDS.To access the shipping information for this material, use the link on the product detail page for the product. 

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

    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.

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

    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.

Top-illuminated flexible organic solar cells with a high power conversion efficiency (≈6.75%) are fabricated using a dielectric/metal/polymer (DMP) electrode. Employing a polymer layer (n = 1.49) makes it possible to show the high transmittance, which is insensitive to film thickness
