Note:
(SAM Category 1.1.1.) Morphing thin sheets, or two-dimensional (2D) materials, into programmed 3D structures presents a newparadigm for additive manufacturing. The PI’s group has developed a 2D material programmingapproach for 3D shaping (digital light 4D printing), which prints 2D hydrogels (hydrogel sheets) encodedwith spatially controlled “growth” (expansion and contraction) and transforms them to programmed 3Dstructures. Despite its potential as a scalable, customizable, and deployable manufacturing technology,lack of programmable materials and how to design them remain a key challenge. Such 3D shapingprinciples have mostly been limited to soft tissue-like hydrogels and thus bioinspired and biomedicalapplications in aqueous environments. The goal of this project is to discover how to program ionicliquid-based polymeric materials with 2D growth (expansion) to enable scalable and customizablemanufacturing of 3D structures of soft conductive materials (ionogels and ionoelastomers). To achievethis goal, this project will integrate additive manufacturing, soft materials science, and digital geometryprocessing. It will pursue three distinct yet synergistic objectives: (1) investigate how to program 2Dionogels for their 3D manufacturing; (2) investigate post-printing polymerization of ionic liquids inionogels to manufacture 3D structures of double-network ionoelastomers with enhanced mechanicalproperties; and (3) manufacture temperature-responsive shape-morphing 3D structures of ionogels andionoelastomers (4D materials).
