These studies focus on the development and understanding of low surface tension polymeric coatings from colloidal dispersions containing fluorinated and non-fluorinated copolymers using bio-active dispersing agents. This is achieved by polymerization of methyl methacrylate (MMA), n-butyl acrylate (n BA), heptadecafluorodecylmethacrylate (FMA) monomers in aqueous environments under monomer starved conditions in the presence of phospholipids (PL). Significant differences in morphologies were obtained by changing the MMA/nBA ratios, thus leading to different coalescence mechanisms and very low static and kinetic coefficients of friction.
