Hello Researchers,
I'm making a composite using PEDOT:PSS as a conductive filler and PDMS as a stretch elastomer to make a conductive patch for healthcare monitoring.
The mixing of the two is very good using surfactants, etc., but make it into a film, bubbles continue to form in the film.
This is the same situation when I dry it in a vacuum oven or in a normal oven. Do you know how to solve this problem?

The mix of filler and polymer in a container must be connected to a vacuum pump for some duration depending on the quantity of mix in order to remove the air bubbles. This operation is called 'degassing'. Then the mix can be transferred slowly for film production.
