Objective:
Dendritic polymers recently have been shown to encapsulate polycyclic aromatic hydrocarbons (PAHs) and other hydrophobic materials. We hypothesize that similar interactions will occur with crude oil components, thus allowing oil to be dispersed. Our objective is to gain a fundamental understanding of the interactions of dendritic polymers with crude oil, taking toxicity and biodegradability into consideration. Our community outreach program objectives are to involve community groups in developing the research and in educating a broad audience about current and novel dispersants and their environmental impacts.
