一般描述

XGnP® 石墨烯纳米片是独特的纳米颗粒，由片状的石墨烯片的层叠组成。
xGnP® 石墨烯纳米片的独特尺寸和片状形态使这些颗粒在提供阻隔性能方面特别有效，而纯石墨成分更使其成为出色的电和热导体。xGnP® 石墨烯纳米片可以改善机械性能，例如基质材料的刚度、强度和表面硬度。
xGnP® 石墨烯纳米片几乎可以与所有聚合物相容，可以作为油墨或涂料中的活性成分，并且是所有类型塑料的极佳添加剂。其独特的制造工艺是非氧化性的，因此该材料具有sp2碳分子的原始石墨表面，特别适合于需要高电导率或导热率的应用。
C 级颗粒通常由亚微米的薄片聚集体组成，粒径小于 2 微米，典型颗粒厚度为几纳米——具体取决于表面积。通常，C 级颗粒具有很高的表面积和大孔隙率。C 级颗粒有不同级别，平均表面积为 300、500 和 750 m2/g。

应用

  • 超级电容器电极。
  • 锂离子电池的阴极材料。
  • 电池电极的导电添加剂。
  • 导电油墨。
  • 导热膜和涂层。
  • 轻质复合材料的添加剂。
  • 用于EMI屏蔽的薄膜或涂层。
  • 化学和生化传感器的基材。
  • 包装用阻隔材料。
  • 超强混凝土的添加剂。
  • 金属基质复合材料的添加剂。

其他说明

石墨烯纳米片具有天然存在的官能团（例如醚、羧基或羟基），可以与大气湿气反应形成酸或其他化合物。这些官能团存在于颗粒的边缘，并且它们的wt％会随粒度而变化。

750 m2/g 的表面积是平均表面积。

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
