In present paper, five non-ionic emulsifiers with different hydrophobic and hydrophilic groups were synthesized to discuss effects of emulsifier on monolayer structure and evaporation resistance. After testing the evaporation resistance, the dispersion rate and stability of the monolayers prepared from different emulsifiers were characterized. It could be inferred that compared with dispersion rate, stability seemed to be the more important factor which might control the monolayer performance, and emulsifier with small volume and strong interaction force between chains might be beneficial to decrease water evaporation.
