I would like to assess the morphology of Zn particles in anode gels using SEM but it is not possible because the gels obviously contain liquid. One of the ways to do it is to use cryo-SEM but unfortunately, we do not have one. Another way is to dry the sample either by heating or freezing the samples. I am not fond of using the heat method as it could change the morphology. I am more keen to use the freeze dry method. However, freeze dry can make the samples to have pores due to sublimation process. Does anybody on here know the best way to freeze dry anode gels?
