method	mass thickness	efficiency/%	advantages	disadvantages
electro-spraying	mg/cm²	80～90	high efficiency; homogeneity (2%～5%); simple equipment	impurities from solvent; thickness limitation
electro-deposition	μg/cm²～mg/cm²	90～100	high efficiency; fast and simple; no cross contamination	impurities from solvent; deposits composition is unknown
vacuum evaporation	μg/cm²～mg/cm²	5～10	the coating is smooth; the thickness homogeneity is high	low efficiency; time-consuming preparation of the material for evaporation; substrate is easily deformed by heat
magnetron sputtering	μg/cm²～mg/cm²	20～40	the coating is smooth, strong adhesion of coating	big amount of the evaporated materials are required
polymer assisted deposition	μg/cm²	80～90	simple, the coating is smooth	thickness limitation
