Oil dispersants are used today to disperse spilled oil from waters in the marine environment and in coastal and inland waters. These dispersants do not prevent fouling of substrates such as birds, animals, and plants by the spilled oil. The objective of this research was to mitigate the deposition of oil on solid coastal surfaces including soil, sand, plant and wild-life, in response to the Deepwater Horizon incident.
Using high-throughput investigation of emulsification, combined with deposition measurements using quartz crystal microbalance and atomic force microscopy techniques and light scattering to characterize of droplet dispersion distribution, we have developed dispersants based on bilayer-forming surfactants and amphiphilic polysaccharides. Once dispersed by these systems, the dispersed oil does not wet nor spread upon hydrophobic substrates such as bird feathers.
