Surface modified polyester polyurethane foams with varying pore sizes for decanted water treatment in oil spill response
by Puwaner Guo, D. Jordan Bouchard and Amy Bilton, University of Toronto.
Testing of two polyurethane foams as absorbants for oil spill remediation is examined, and a surface treatment to enhance oil removal efficiency is explored by the authors. This work is said to be crucial in determining the optimal foam formulation for oil spill cleanup.
