F-Si3-EO8) tend to lie flat in the air/water interface and result in an increasing the surface tension at the CMC ( γCMC) and single trisiloxane surfactant molecule at the air/water interface ( A min) values. Following the difference in the intermolecular forces and molecular volumes (CH3- < ClCH2- < CF3-), the γCMC values decrease following the order Me-Si3-EO8 > Cl-Si3-EO8 > F-Si3-EO8, and the adsorption
