Descripción general

Poly (sodium 4-styrenesulfonate) (PSS) a cation exchange polyelectrolyte.[1] PSS may be used to produce mechanically stable and very reproducible coatings.[2]

Aplicación

Reduction of graphite oxide in the presence of PSS has been reported for the synthesis of polymer-coated graphitic nanoplatelets.[3] Interaction of PSS with metal ions has been studied.[2] PSS combined with Nafion has been reported to be used a mixed coating of Bismuth film electrodes.[4]

We describe the use of PEDOT:PSS conducting polymer microwires to modulate action potentials in single cells. PSS conducting polymer microwires are electrochemically synthesized with diameters ranging from 860 nm to 4.5 μm and conductivities of ~30 S/cm. The length of the microwires is

Professor Rivnay (Northwestern University, USA) discusses using organic mixed conductors as an alternative to efficiently bridge the ionic world of biology with contemporary microelectronics.

We present an article that discusses two applications in particular; first, using these layers as polyelectrolyte membranes to control permeability.

Questions

1–2 of 2 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.
