Abstract
Hydrophobic and oleophilic polymethacrylates with moderate crosslinking have been increasingly used for oil cleanup. In view of oil recovery and absorbent reusability, the particle-like polymethacrylates are not satisfied completely due to flaccid absorption and unfacilitated assembly. Fiber is now considered as an optimal candidate for oil absorbents. This review summarizes the most promising approaches to fabricate polymethacrylate fibers including post-crosslinking, low-crosslinking (physical crosslinking or entanglement), and blend, and then illustrates the structure-property relations of as-prepared materials. The resulting polymethacrylate fibers are effective oil-absorptive materials because of fast absorption, facility, reusability, and easy disposal, pointing to the immense potential for future development.
