- 요약Mastery of structure-property relationships is the defining feature of success in application targeted engineering. At the forefront is the development of smart, stimuli-responsive, auto-regulating, even fully autonomous, materials. Hydrogels show immense promise in these contexts for wide array of applications due to simple, tunable synthesis, unique hierarchical structures, and controllable stimuli-responsiveness. It is no surprise interest regarding development of hydrogel sensors and actuators continues to grow explosively. In this context, their high sensitivity, fast response, low fabrication cost, and diverse responses are what garner attention.The strategies for transducing these responses range, but often utilize equipment to measure minute changes in the material. The costly nature of such equipment and rigidity of the inorganic materials used to interface soft components counteract the original advantages of utilizing hydrogel-based sensor/actuators, rendering the overall system slow, inaccessible, and biologically incompatible in many cases. Hydrogel sensors capable of self-reporting values to the naked-eye, as well as compliant, biocompatible hydrogel actuators for soft robotic devices, are needed. Meanwhile, surface-instability phenomena have been widely documented in elastic films for years, with clear pathways for control of the resultant morphology. Here, through deeper understanding of structural mechanisms, a series of hierarchically emergent structure-properties are revealed, building up from mechanical theory of wrinkling surfaces to a novel mode of information transduction, advanced logic-gating capabilities, and lead to exploration of discovered irregular solvent-salt-polymer structure-property influences.In Chapter 1, fundamental principles and background regarding significant structure-properties in hydrogels. In Chapter 2, proof of concept of adapting instability induced scattering as a transduction method through a engineering forward design. In Chapter 3, realization of universal design template and in situ use. In Chapter 4, novel construction of instability induced sensors and actuators to form soft robotic logic gates . In Chapter 5, investigation of divergent non-aqueous specific ion effects and its effect to tune organogels and produce emergent critical temperature response. In Chapter 6, a summary of future outlook of the non-aqueous specific ion effects, their adoption for multi-sensitive instability induced scattering actuators, and beyond to bridging innovation in new organometallic materials via first of its kind sequential infiltration syntheses.
