Abstract
A composite of polyurethane foam grafted with carbon nanofibers is described. This composite foam may be made by contacting and drying a polyurethane foam with a suspension of carbon nanofibers and then drying. Additional carbon nanofiber layers may be added with repeated contacting. The composite film has a high surface area of 276 m/g and a hydrophobic character that may be exploited for separating an oil phase from water.
