摘要: The mixing behavior of binary monolayer fatty acid was investigated on the basis π-A isotherm measurements. (palmitic acid(C16)/arachidic acid(C20)) and (C20/lignoceric acid(C24)) mixed monolayers were in a miscible state, whereas (C16/C24) an immiscible state. (C16/behenic acid(C22)) (stearic acid(C18)/C24) incomplete dependence difference number methylene group between components is probably due to enthalpic contribution based cohesive energy components.
