I tried to coat the particles with polymer (PMMA in THF). The procedure I followed was: I prepared a dilute solution of polymer, and simple poured the particles into the solution at continuous stirring. Then, I evaporated the solvent at room temperature and also tried evaporating it by raising temperature during stirring. I found that particles were agglomerated through FESEM. I would like to know that whether the procedure I followed is correct, if not please suggest improvements. I want the coated particles in the dispersed form, so that after coating, freely flowing powder is obtained.
Moreover, will the addition of surfactant into the polymer solution before the incorporation of the particles help in serving the purpose (means will the particles not stick thereafter?)
Please guide
The experimental conditions are related to the molecular structure and the physico-chemical properties of the coating compounds. The hydrophilic and hydrophopic behaviour of polymeric materials in aqueous solutions, as well as the determining parameters involved, they have been extensively investigated in the relevant literature. The following studies could be also helpful to quantify the agents used and the experimental process of your analysis:
