Liquid drop contact angle: THF, mica & graphite

Click For Summary
SUMMARY

The discussion focuses on the contact angle of tetrahydrofuran (THF) on mica and graphite substrates. Participants agree that the contact angle is expected to be very small due to THF's excellent wetting properties on these materials. The challenge arises from THF's rapid evaporation at room temperature, complicating the measurement of this angle. References to Adamson's work suggest it may provide useful insights, although no specific experimental values are readily available.

PREREQUISITES
  • Understanding of liquid drop contact angle measurement techniques
  • Familiarity with tetrahydrofuran (THF) properties
  • Knowledge of mica and graphite as substrates in wetting studies
  • Basic principles of surface chemistry
NEXT STEPS
  • Research contact angle measurement methods for volatile liquids
  • Explore Adamson's "Physical Chemistry of Surfaces" for relevant theories
  • Investigate the effects of evaporation on contact angle measurements
  • Examine studies on wetting properties of THF on various substrates
USEFUL FOR

Researchers in surface chemistry, materials scientists, and anyone studying the wetting behavior of liquids on solid substrates, particularly those working with tetrahydrofuran.

This is a long shot, but maybe someone will know or can point me in the right direction. I'm looking for an experimental value for the contact angle between tetrahydrofuran (THF) with both mica and graphite substrates. I've done numerous googling and also did a search on the web of knowledge to no avail. I know the angle will be very small because THF wets both of those substrates quite well.

I suspect no measurements have been made however as THF evaporates in a matter of seconds at room temperature/pressure, but even so...

Thanks

You're into "splitting hairs" over the differences between "six" and "half a dozen" here. Adamson might help you.
 
Thanks, I will check out the book. Indeed you are correct about splitting hairs, I'm thinking that it might be best to just state that the angle is very small, but I would like to put a upper limit on it, I may have to make an estimate somehow. I will still have a look in Adamson just in case, thanks again!
