A bionic uncoated non-stick titanium pan

and honeycomb structures. The cooking oil was easily stored and anchored by the multi-scale structures to form an oil film which reduced the adhesive strength between the pork and the pan. The honeycomb structures effectively protected the microstructures from being scraped off by kitchen cleaning utensils and improved the abrasion resistance of the pan. Owing to its excellent performance and bioinspired design, the fabricated bionic uncoated non-stick titanium pan exhibits broad application potential, particularly in an era marked by increasing health consciousness.
