| Abstract |
|
Dendritic polymers have recently been shown to encapsulate polycyclic aromatic hydrocarbons (PAHs) and other hydrophobic materials. We thus hypothesize that crude oil can be dispersed using these materials. Our objective is to gain a fundamental understanding of the interactions of dendritic polymers with crude oil, taking toxicity and biodegradability into consideration. First-phase laboratory results show that poly(amidoamine) dendrimers and hyperbranched poly(ethyleneimine) polymers form complexes with linear (hexadecane) and polyaromatic (phenanthrene) hydrocarbons, increasing the dispersion of these model crude oil components. Ongoing efforts are examining the effects of hydrocarbon-polymer complexes on algal species to determine their biocompatibility. Dendritic polymers will be compared with Corexit 9500A and other conventional dispersants. As a part of this project, community outreach workshops will carry the research knowledge to the public and allow community groups to participate directly in laboratory studies. |
