General description

Mixed monolayers of 1-octadecanol and ethylene glycol monooctadecyl ether were studied to investigate their evaporation suppressing performance. The rate dependence of the collapse pressure for an octadecanolmonolayer using axisymmetric drop shape analysis has been investigated.

Application

1-Octadecanol has been used as surfactant for the functionalization of carbon nanotubes.
