en.Wedoany.com Reported - A study on the EDPE self-healing superhydrophilic coating reveals that this on-demand adhesive underwater coating can be used to balance requirements such as strong adhesion, oil resistance, and durability. The research team drew inspiration from the temperature-responsive mechanism of tardigrades and the superhydrophilic properties of fish mucus to construct a multi-level biomimetic structure, enhancing the performance of the EDPE self-healing superhydrophilic coating in underwater environments.

Experimental results indicate that the EDPE self-healing superhydrophilic coating can maintain structural integrity and underwater superoleophobic performance even after 160 friction cycles and exposure to extreme conditions such as pH 2, pH 12, and artificial seawater. The coating can also restore its oil-repellent capability through self-healing after damage and can achieve repeatable on-demand adhesion on various material surfaces, demonstrating good environmental adaptability.

In addition to adhesion and durability, the EDPE self-healing superhydrophilic coating also exhibits antifouling, drag reduction, and antibacterial effects. Molecular simulations explain the adhesion mechanism of Ly-1, and experiments have also verified its antibacterial properties. These characteristics give the EDPE self-healing superhydrophilic coating application potential in marine, medical, and industrial scenarios, particularly suitable for high-performance underwater coating solutions that require scalable manufacturing. The related findings have been published in "Progress in Organic Coatings".
