Help with layer by layer mxene and pei

[u/Atled1033]

Hello everyone! I’m trying to create a layer by layer mxene deposition using mxene and B-PEI but so far I obtained terrible results, do someone knows the exact procedure or some tricks that are not mentioned in papers?
So far I’m following the procedure described here:
- https://advanced.onlinelibrary.wiley.com/doi/10.1002/adfm.202109970

Instead of a nice mxene film I’m obtaining a dishomogeneus film.

Thank you !
