From technology that simply contains oil spills, researchers have developed material that repels and facilitates the self-removal of oil particles on surfaces.
For environmental insurers, the use of this new technology could spell lower liabilities in the event of oil spills.
Aalto University researchers developed an oil repellent material that moves oil particles to directions predetermined by patterns in the surface. It uses the energy on surfaces like water (surface tension) to move oil to the desired direction.
This development applies to oil containment by opening avenues for removal using surface tension on water, which is relevant since most spills occur on bodies of water.
Specifically, the material sets a pattern where oil will move to its centre without the need for external energy sources. Research has found that this material also causes oil droplets to position themselves accurately at the centre of the pattern.
Currently, response teams use bulky equipment such as metal and plastic booms to contain oil spills on seas and oceans, where most rigs are located. These methods are not always efficient, cost a lot to execute, and do not effectively contain the damage of oil spills.
Some burn the oil on site, which has repercussions on the environment and come with hefty liabilities.
