hi,anyone can give me suggestion how to remove crosslinked polystyrene using wet etching or isotropic plasma etching? Is there any solvent which can dissolve crosslinked PS? I am using PS nanoporous template to build nanohouse:filling Au into nanoporous and cover the surface as roof. The pore is 20nm in diameter and spacing is 30nm and template thickness is 30nm. That is why it is difficult to remove the crosslinked PS(the matrix) underneath the Au roof. Thanks a lot!
