Abstract
Fabrication of the helical fibers with sheath/core structure comprising 3D interconnected porous polystyrene (PS) and ductile polyvinylidene fluoride is inspired by coiled plant tendril. The key innovation point applied in this study is to produce a helical porous system based on sheath/core structure that can come into being a huge storage space in the sorption process for crude oil. More importantly, the mechanical properties confirm to have a more excellent improvement than that of the initial PS fibers, which make it become a possible candidate for the large‐area sorption and reuse of crude oil from the ocean or industry. The bioinspired fabricating strategy opens a significant avenue between the coaxial electrospinning and crude oil contamination cleanup. It is also expected that the unique structure can make it a promising candidate for applications in energy conversion, tissue engineering, and intelligent devices.

The long-term that could be used for cleaning up crude oil leakage, typically catastrophe of marine ecosystem and the loss of resource by with inexpensive cost, facile fabrication process, and excellent crude oil leakage call for an urgent need to develop advanced oil cleanup properties
For the helical porous fibers with sheath/ core structure, the results manifested that the size of cavities could be adjusted by the solutions feed rate ratio of outer and inner pipelines based on the experiment
Summary
(controlled burning, chemical dispersants, and the use of solidifiers),[4,5,6] bioremediation,[7] and physical methods (booms, skimmers, and sorbents).[8,9,10] most of these methods only focus on candidate for the large-area sorption and reuse of crude oil from the ocean cleaning up, ignoring the squander of or industry. The forming fiber is continuously traveling, and the inner elongated core with excellent scalability occurs to shrink, which induces the formation of helical shape (Figure 2b).
