A very large number of elastomer variants have been developed over the past decades, and the flexible materials of different hardnesses that are easy to process have become popular, used in a wide range of applications. These areas could be further expanded if elastomers original properties of elastomers by adding new useful properties through functionalisation new functionalities. For example, elastomers that respond to magnetic or electric fields by dimensional changes can be in control and regulation systems with microstructured elastomer surfaces can be used to make superhydrophobic tank liners that can be emptied perfectly.
