In the wet transfer method (pmma assisted method), after using the TEM grid to fish up the PMMA film with MoS2, we need to dissolve the PMMA film. Following a lot of literature, I use acetone to dissolve the PMMA. As we know, the structure of the TEM grid is made of a holey carbon film and a formvar film, then the Cu grid. I am worrying about whether the acetone will dissolve the formvar film?

Anyone can give me some suggestion about how to prepare the TEM sample and which type of the TEM grid  I should choose?
