Teflon & Alkoxides: Fact or Fiction?

[osskall]

Hi!

I heard from somebody that teflon might react with some alkoxides, and that this is actually what DuPont uses in some cases to make the teflon coatings stick to cookingware or whatever is coated in these specific cases.

This bothers me since I have a cuvette with a teflon stopper, which is stuck. Inside the cuvette is toluene with: an alkoxide. Has my alkoxide reacted with the teflon?

Does anyone know more about this?
I searched on the internet and information on reaction of teflon with alkoxides is scarce. Is this just a myth? For as far as I can see, alkoxides are used to make different modifications of the perfluorinated polymers with alkoxy groups in them, but I cannot find anything on e.g. making teflon coatings stick with the help of alkoxides.

Hello!

Thank you for bringing up this topic. I can assure you that the reaction between teflon and alkoxides is not a myth. Teflon, also known as polytetrafluoroethylene (PTFE), is a highly inert and non-reactive material. However, it can react with certain chemicals, including alkoxides.

In the case of DuPont using alkoxides to make teflon coatings stick, this is most likely referring to the process of chemical grafting. This involves using a reactive molecule, such as an alkoxide, to bind to the surface of the teflon and create a stronger bond between the coating and the surface it is applied to.

In your situation, it is possible that the alkoxide in your toluene solution has reacted with the teflon stopper in your cuvette, causing it to become stuck. I would recommend consulting with a chemist or contacting the manufacturer of the cuvette for further information.

I hope this helps answer your question and provides some clarification on the topic. It is always important to be aware of potential reactions between chemicals and materials, especially when working with sensitive equipment. Thank you for your curiosity and desire to learn more about this topic.

Hi there!

The use of alkoxides in combination with Teflon coatings is not a myth. In fact, DuPont does use alkoxides to help the Teflon coatings adhere to surfaces. However, this reaction is carefully controlled and monitored to ensure that it does not affect the properties of Teflon or create any harmful byproducts.

In regards to your specific situation with the teflon stopper and alkoxide in the cuvette, it is possible that a reaction has occurred. It is best to contact the manufacturer or a chemist for further assistance and advice on how to safely remove the stopper. It is always important to handle chemicals and substances with caution and follow proper safety protocols.

I hope this helps clarify your concerns about Teflon and alkoxides. It is always important to gather accurate information and consult experts when dealing with potentially hazardous materials.
