Hi, I want to ask about the process of removing the Surfactant (Pluronic F127) from exfoliated graphite before characterizing it via TGA?
Should I wash with DI water couple of times and then filter it using nylon filter membrane? Thank you!
Hello, drying to constant weight mean that weight after drying not changing in drying process after final two measurements.
It is better to rinse with water and centrifuge, then repeat the operation with ethyl alcohol. Then dry to constant weight.
Warm water and alcohols like EtOH, MeOH, can help you to remove Pluronic surfactants.
Dear Yuri Mirgorod , thank you for your message. What did you mean by "dry to constant weight"? You meant that I can put in a vacuum oven after rinsing and I dry it before TGA characterization? Thank you
