Electrospinning that stems from electrohydrodynamic theory is a simple and novel way to fabrication nanofiber, by which hundreds of materials have been fabricated into nanofiber.
The applied voltage from high-voltage power supply (DW-P403-1AC, Tianjing Dongwen High Voltage Power Supply Plant, China) between spinneret and collector is 1.7 kV. 16% polyethylene oxide (PEO, MW = 300,000, Dadi Fine Chemical Co., Ltd, China) solution is used as electrospun materials and ejected form the spinneret.

Whether titanium alloy material can be well used in offshore oil and gas pipelines have been evaluated, this study will be a supplement of the research on titanium alloy oil well pipe materials.
The results showed that both titanium alloy materials had better corrosion resistance.
The tests were conducted by referring to GB/T 15748-2013 "Marine Metallic Materials Galvanic Corrosion Test Method" for testing.
It can be concluded that TC27 titanium alloy materials have excellent corrosion resistance and better comprehensive performance, which can effectively meet the needs of high-strength and corrosion-resistant downhole tubing materials.
