Abstract

The surface pressure vs surface area isotherms of monoparticulate layers determined using Langmuir and Wilhelmy film balances depend nontrivially on the amount of spread particles. It is inferred that a surface pressure gradient across the spread particle layers is responsible. An extrapolation procedure for determining correct values of the contact angles is described.
