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.

Inverted Organic Photovoltaic Devices Using Zinc Oxide Nanocomposites as Electron Transporting Layer Materials

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.

Questions

1–10 of 11 Questions  

  1. How is shipping temperature determined? And how is it related to the product storage temperature?

    1 answer

    1. Products may be shipped at a different temperature than the recommended long-term storage temperature. If the product quality is sensitive to short-term exposure to conditions other than the recommended long-term storage, it will be shipped on wet or dry-ice. If the product quality is NOT affected by short-term exposure to conditions other than the recommended long-term storage, it will be shipped at ambient temperature. As shipping routes are configured for minimum transit times, shipping at ambient temperature helps control shipping costs for our customers. For more information, please refer to the Storage and Transport Conditions document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/316/622/storage-transport-conditions-mk.pdf

  2. How can I determine the shelf life / expiration / retest date of this product?

    1 answer

    1. If this product has an expiration or retest date, it will be shown on the Certificate of Analysis (COA, CofA). If there is no retest or expiration date listed on the product's COA, we do not have suitable stability data to determine a shelf life. For these products, the only date on the COA will be the release date; a retest, expiration, or use-by-date will not be displayed.
      For all products, we recommend handling per defined conditions as printed in our product literature and website product descriptions. We recommend that products should be routinely inspected by customers to ensure they perform as expected.
      For products without retest or expiration dates, our standard warranty of 1 year from the date of shipment is applicable.
      For more information, please refer to the Product Dating Information document: https://www.sigmaaldrich.com/deepweb/assets/sigmaaldrich/marketing/global/documents/449/386/product-dating-information-mk.pdf

  6. 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.

  7. 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.

  10. 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.
