Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
