A bionic uncoated non-stick titanium pan

Abstract

In today's cookware market, non-stick pans with Teflon coatings exhibit excellent performance and account for the majority of the market share. However, using Teflon coated non-stick cookware is risky and may be harmful to human health. Uncoated non-stick pans are much healthier for humanity but are difficult to fabricate. Herein, a bionic uncoated non-stick pan was successfully fabricated on a titanium substrate, which was inspired from Nepenthes 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.
