Abstract

See full text

Oil spill detection is crucial, both from an environmental perspective and the associated economic losses. Current optical oil sensing techniques, such as underwater microscopy and light scattering methods, mainly focus on detecting the properties of particles or organisms in water and often require costly equipment and sophisticated data processing. Recent studies on graphitic foam show its extraordinary pollutant absorbing properties, with high absorption weight ratios. Here we propose to produce a graphene foam based ultra-light material that changes its optical properties on absorbing oil species. The results demonstrate clear changes in optical transmission and scattering properties of graphene foam when exposed to various oils. The effective graphene foam sorbent can be easily integrated with optic fibers systems to detect the optical property variations and also to monitor oil presence/spillages remotely. Such sensors can also be used for underground oil exploration.
