- 요약This dissertation introduces a "design-by-architecture" approach for the synthesis of biomimetic elastomers and thermoplastic elastomers, employing bottlebrush polymer architectures to achieve precise mechanical property control. Biological tissues exhibit a unique set of mechanical behaviors, including softness, strain-stiffening, elasticity, and viscoelastic damping, which conventional synthetic materials have historically struggled to replicate. The inherent coupling between mechanical properties in linear polymer networks severely limits the independent tuning required for biomimetic performance.In addressing this limitation, the research systematically explores bottlebrush polymers, a class of macromolecules characterized by densely grafted polymeric side chains. This architectural strategy significantly reduces chain entanglements and allows independent modulation of mechanical properties through architectural parameters such as grafting density, side chain length, and crosslink density.Three key studies are presented. The first investigates encoding tissue-like firmness into pressure-sensitive adhesives (PSAs) using linear-bottlebrush-linear (ABA) and randomly grafted (A-g-B) architectures, revealing how precise architectural adjustments can program strain stiffening responses essential for biomimetic adhesion. The second is a detailed examination of how bottlebrush elastomers demonstrate unprecedented orthogonal tuning of elastic modulus and relaxation time through architectural manipulation, effectively decoupling properties that are intrinsically linked in traditional linear chain elastomers. These materials showcase the capability to independently control mechanical softness and damping properties, greatly expanding the design space and potential applications for biomimetic materials.Lastly, the utilization of bottlebrush architecture as a method for encoding mechanoresponsive structurally colored elastomers is demonstrated. This advanced material extends synthetic biomimicry beyond the mechanical realm and into the optical domain by assembling highly precise micro- and nanoscale networks creating photonic crystal derived coloration. Such structural coloration is seen only in rare instances of Nature, such as the blue color of the Morpho butterfly's wings or color changing skin of chameleons.Collectively, this dissertation not only advances fundamental polymer science through an architectural lens but also establishes a robust, additive-free platform for creating materials with biomimetic mechanical and optical complexity. These findings open pathways for the design of cutting-edge biomedical devices, soft robotics, wearable technologies, advanced sensors, and responsive materials that closely replicate biological systems.
