一般描述

聚苯胺 (PAni) 祖母绿盐可通过 PAni 祖母绿碱 (PAni-EB) 质子化制备。当pH > 7 时形成 PAni-EB。在一项研究中解释了它的抗腐蚀剂机理。[1]
聚苯胺（翠绿亚胺基）(PANI-EB)是一种导电聚合物(ICP)，通过苯胺的氧化聚合形成。翠绿亚胺基含有氧化二亚胺和还原二亚胺。PANI可通过掺杂质子酸的p-型将PANI改性为共轭翠绿亚胺基。[2][3]

应用

PANI-EB可与多壁纳米碳管(MWCNT)形成纳米复合材料，用于功能化玻璃碳电极，以执行镉(Cd(II))和铅(Pb(II))的电敏检测。[3]在超级电容器应用中，碳纳米纤维可在PANI-EB上增强，以获得95 F/g的比电容和超过3000次92%的保留率。[4]它可以与七亚甲基亚胺一起作为抑制剂，形成稳定的燃料电池膜。[5]

特点和优势

未掺杂形式的导电聚合物（非导电）。

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.
      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
