One of my sample (NIPs-non-imprinted polymer) couldn't settling down after centrifugation (4000 rpm). Might be due to very fine particles. So what I did, I let the samples to evaporate under fume hood (see attachments). I have tried 2 times but still got the same results. The question is, did my polymerization work? Btw, I have no problem with the counterpart polymer particles (MIPs)
Dear Zulkarnain Mohamed Idris, since you have this solid/powder, you can check if it is a polymer or not, for exemple by measuring the molecular weight, chemical/spectroscopy titration of the reactive sites towards polymerization, ...etc. You didn't mentionned any of the reactants used to get a clear vision on your work. My Regards

1) Choose a suitable solvent for the polymer.
2) Check the polymer is soluble at room temperature. If not, stirrer the solution (polymer + solvent) below 30 to 50 degrees Celsius of the glass transition temperature, and continue until the solution becomes transparent or soluble.
3) keep the solution in petri-dish or as per you methods. Curing time depend on the amount of solvent, and curing methods.
