Adhesion between transferrable monolayer and substrate ?
Wed, 2010-05-26 05:55 - Xianghui Zhang
Is there any research about interfacial adhesion of transferrable monolayers and substrates ? I found it's quite different from the rough surface model, because the monolayer is flexible enough to match the roughness of surface. Can one determine the separation value from the different roughness of pure substrate and substrate with a monolayer ?
Can someone give me some clue ? Thanks a lot!

graphene monolayer on substrate
I am not sure what monolayers you are interested in. Here is a study on graphene monolayer on substrate , which presents an analysis on the effect of adhesion energy on separation and morphology of graphene on both flat and rough surfaces.

Thank you for the paper, RH
Thank you for the paper, Rui Huang, I will read it carefully.
The monolayer I am investigating is cross-linked biphenylthiol self-assembled monolayers (SAMs) which is 1 nm thick. It can be transferred to any solid substrate or holey structures.
According to your understanding, do you think that any experiments (e.g. RMS roughness determined by AFM) can be done to examine the interfacial adhesion between monolayer (graphene or SAMs)and substrate?

SAMs
My colleague, Ken Liechti, once worked on SAMs using Interfacial Force Microscope (IFM). The paper below might be of interest to you:
