This video is a tutorial on performing O2 plasma treatment of PDMS using a microwave oven. The demonstration includes how to set up the treatment, as well as testing the hydrophobicity of the treated PDMS.

Why all the stupid comments? It is clearly just a demo for a lab as part of a course not a stand alone video. Personally as I know what plasma treatment of PDMS is for I found it really great to see I could do it with such simple equipment.
This is a way to treat the surface of the PDMS so that it will bond to glass. It is an alternative to the corona treatment shown in 6B, albeit less effective. More supplemental material can be found on the OCW website
Lol, people are so impatient and snobby in the comments. I found this video helpful for my research work. The video appears to be for a lab course at MIT.
Is the microwave watt affect the plasma formation, how much aluminum fold you add in the jar, thanks
I asked for a PDMS in my local grocery and they hadn't. I have microwave oven though.
Thanks for the video. I set mine up and it's working beautifully. I'm trying to do the same type of treatment to a thin film of mylar (~25um) (PET, polyethylene terepthalate); however, the plastic melts and deforms when I do the treatment (PET melts at 260 C). Is there any robust way to control the power of the plasma / reduce its temperature?
The temperature of the plasma is directly related to the pressure your are able to get, lower the pressure, lower the temperature. Google cold plasma if you want more info.
@@matt3251 Great tip!
Does anyone know where I can get a lid like the one on the glass jar? I can't seem to find one anywhere.
Laura von Deak Drill a hole in a normal plastic lid. Choose your drill bit based on the valve you want to install. Use a bit of teflon tape to help the seal.
Thank you so much!
cool
I assume this material is part of the course and made for people who know what this is for. I am not one of them.
What?
what is the aim of the experiment what do u want to show us what is the use of it
It allows you to chemically covalently bond the PDMS glass organic polymer to a glass surface. The PDMS will repair itself over a couple hours once bonded, but it is vulnerable to water and other stuff until then. Use an ionization generator or corona discharge blower instead of putting this in the microwave. Its easier.

what is going wrong with the voice 2:12
polydimethylsiloxane = PDMS
Needs a thesis statement. What are you trying to accomplish? You had plenty of dead air time to explain it in a few simple phrases.
With science, communication is key, this is dry and useless.
Just curious, do you work in this particular field? Because, to me, there are countless, obvious ways this is useful. Bonding PDMS to glass, preparing surfaces, bonding photoresist, and a bunch of other things.
I don't approve of the microwave method, but I do not think it requires an explanation for people who would seek this out. For the layman, absolutely, it would be nice to have a thesis, but no introduction is needed for the people who know what this is.
