Descrizione generale

Benzoyl peroxide participates in the covalent insitu functionalization of carbon nanotubes. On heating, it undergoes decomposition to afford phenyl free radicals and CO2 gas.[1]
Luperox® A98, Benzoyl peroxide, an anhydrous benzoyl peroxide powder, is a mainly used as a thermal free radical initiator in polymerization reactions.

Applicazioni

Benzoyl peroxide has been used as an initiator in the preparation of the following:
  • Thermal cross-linking of multiwalled carbon nanotubes (MWCNTs) via radical-initiated reaction[1]
  • 3-D crosslinked carbon scaffolds[1]
  • poly(lactic-co-glycolic) acid (PLGA), MWCNT and singlewalled carbon nanotubes (SWCNT) scaffolds[2]
Widely used initiator, curing agent, and cross-linking agent in polymerization processes.

We report a simple method to fabricate macroscopic, 3-D, free standing, all-carbon scaffolds (porous structures) using multiwalled carbon nanotubes (MWCNTs) as the starting materials. The scaffolds prepared by radical initiated thermal crosslinking, and annealing of MWCNTs possess macroscale interconnected pores

1–3 di 3 domande  

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

    1 risposta

    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 risposta

    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.
