Bioinspired structural adhesives have shown great potential in the field of industrial manipulation and locomotion. However, such adhesives usually perform great adhesion performance at room temperature, reliable adhesion under high‐temperature conditions remains a major challenge and is rarely investigated, which severely limits the applications of current bioinspired adhesives. Here, a bioinspired adhesive structure based on fluororubber (FKM) and nanofillers is proposed. The adhesive structure has a “suction cup‐shaped” tip that mimics the special structural configuration of the adhesive setae of Dytiscus lapponicus, and the ability to regulate the structural modulus by adjusting the content of nanofillers, as well as exhibiting strong and contamination‐free adhesion (>350 kPa) with high adhesive efficiency (up to 77.7) in a wide temperature range (from room temperature to high temperatures (>200 °C)). Moreover, the adhesion performance can be enhanced by precisely regulating the structural modulus, and the enhancement mechanism is demonstrated based on the cohesive zone theory. The proposed adhesion strategy expands the application areas of dry adhesives from room‐ to high‐temperature conditions, especially for the pick‐up and transfer of thin and fragile materials that require high‐temperature operation, opening an avenue for the development of devices and systems based on dry adhesives.
