So is there some kind of cohesive network action between the polymer
solution keeping the thickness uniform, or does in fact the thickness
of a spin-coated layer vary from the center to the outside edge
(molecules in center feel lower Gs than molecules at the
Would it make sense to spin-coat something on a plane parallel to the
axis of rotation? Like those carnival rides where you stand up against
the inner side of a circular wall, and the ride spins around pressing
you to the wall. Replace the wall with a flat piece of polished
aluminum, and you with some gel that you way to spread evenly.
