Dear all,

I am wondering is there any expert who is familiar the so-called
"floating" method to float a thin polymer layer (e.g. PMMA, PS, etc)
onto water surface from a solid substrate (usually glass)?  It was
mentioned many times in literature without any details.  Looks like
"trivial" but I did not success.  In particular, I am wondering how
larger the film can be floated off and how to do it correctly (like
inclination angle)?  Any tips or tricks?

Thanks in advance.
