The interfacial behavior of cellulose nanocrystal (CNC) surfactants (CNCSs), formed by the interactions between CNCs dispersed in water and amine terminated polymer dissolved in oil, was investigated usingin situatomic force microscopy (AFM) as a function of pH and areal density of CNCSs. The AFM results show that the strength of the interactions between the CNCs and the ligands dictates the response of the CNCS assemblies to an applied compress whether the assemblies wrinkle or buckle or if the orientation of the CNCSs with respect to the interfaces is changed. AFM force curve measurements provide an alternative route to evaluate the interfacial tension and, more importantly, allow quantitative evaluation of the strength of interactions between the CNCs assembled at the interface.
