I am trying to increase the adhesiveness of polystyrene using 3-glycidoxypropyltrimethoxysilane, but do not either have a good protocol or dont have the right silane. Can anyone help please.
I think that silanes are no good solutions for this problem. The silane will not react with polystyrene. I would suggest using gas plasma treatment (corona discarge). Even then the treatment should be done immeiately before applying the gel, otherwise the surface will become hydrophobbic again.
