Abstract
Abstract Modern materials science has witnessed the era of advanced fabrication methods to engineer functionality from the nano‐ to macro‐scales. Versatile fabrication and additive manufacturing methods have been developed, but the ability to design a material for a given application is still limited. Here, we introduce a novel strategy that enables target‐oriented manufacturing of ultra‐lightweight aerogels with on‐demand characteristics. The process relies on controllable liquid templating through interfacial complexation to generate tunable, stimuli‐responsive 3D‐structured (multi‐phase) filamentous liquid templates. The methodology involves nanoscale chemistry and microscale assembly of nanoparticles (NPs) at liquid‐liquid interfaces to produce hierarchical macroscopic aerogels featuring multi‐scale porosity, ultra‐low density (3.05‐3.41 mg cm −3 ), and high compressibility (90%) combined with elastic resilience and instant shape recovery. We overcome the challenges facing ultra‐lightweight aerogels, including poor mechanical integrity and the inability to form predefined 3D constructs with on‐demand functionality, for a multitude of applications. The controllable nature of the coined methodology enables obtaining tunable electromagnetic interference shielding with high specific shielding effectiveness (39,893 dB cm 2 g −1 ), and one of the highest‐ever reported oil absorption rates (48,728% for chloroform). These properties originate from the engineerable nature of liquid templating, pushing the boundaries of lightweight materials to systematic function design and applications.
