- 요약The global demand for sustainable energy technologies, coupled with the need for biocompatible and environmentally friendly materials, has spurred intense efforts to identify functional material platforms that are both efficient and adaptable. Traditional inorganic and synthetic polymeric materials often provide high performance but lack sustainability and compatibility with biological systems. In contrast, bio-derived materials offer unique opportunities to bridge this gap, particularly for applications in bioelectronics and biomedical devices, where environmental compatibility and safe integration with living systems are essential. Among bio-derived materials, amino acids stand out as versatile molecular precursors capable of forming ordered crystalline structures, supporting proton conduction, and enabling electronic transport when incorporated into composite systems. This thesis is dedicated to advancing the design and synthesis of amino acid-based functional materials, with a particular emphasis on enhancing their performance through integration with polymers and hybrid structures. By systematically exploring piezoelectric, proton-conducting properties of amino acid composites, as well as their environmental utility in carbon dioxide (CO2) capture, this work demonstrates the breadth of functionality accessible through amino acid chemistry. The results presented herein highlight molecular-level design strategies for engineering bio-derived materials that can contribute to the fields of energy harvesting, sustainable bioelectronics, and environmental remediation.Chapter 1 provides a comprehensive background overview of the topics of this thesis. It outlines the global energy challenge, the role of bio-derived materials, and the potential of amino acids in energy and environmental applications, including piezoelectricity, proton conducting, and carbon capture.Chapter 2 focuses on the orientation-controlled growth of amino acid crystals and the related piezoelectric properties. A nucleation-controlled strategy was developed to enhance the alignment and crystallinity of glycine domains within a poly(vinyl alcohol) (PVA) matrix. This approach yielded membranes with improved piezoelectric performance, which were further demonstrated in a simple device for mechanical energy harvesting. The chapter provides fundamental insights into structure-property relationships in bio-derived piezoelectric systems and illustrates their potential for powering small-scale, biocompatible electronic devices.Chapter 3 describes amino acid-based proton-conducting membranes inspired by natural protein channels. Poly(acrylic acid) (PAA)-amino acid-glycerol composites were synthesized and systematically studied to understand the influence of amino acid type, humidity, and other environmental factors on proton conductivity. The optimized cysteine-containing films demonstrated strong potential for electricity generation from ambient moisture, highlighting their applicability in self-powered sensors and bioelectronic interfaces. This work underscores the value of amino acids as tunable components for designing sustainable proton conductors with biomedical and environmental relevance.Chapter 4 introduces a new class of conductive hydrogels derived from amino acids, designed as active materials for organic electrochemical transistors (OECTs). By tailoring the molecular interactions between amino acids, polymers, and additives, hydrogels with significantly enhanced conductivity and mechanical stability were achieved. These hydrogels exhibited promising performance when tested as OECT active layers, suggesting a path toward biocompatible, environmentally benign materials for bioelectronic and biomedical devices. Chapter 5 expands the scope of amino acid functional materials to environmental applications by developing metal-amino acid complexes for carbon dioxide capture. Using a simple solution-based synthesis approach with pH control, hybrid sorbents with tunable binding affinities were obtained. The Cu-D-Glu sample exhibited outstanding carbon capture performance with comparable capacity and fast adsorption/desorption kinetics. The chapter demonstrates that amino acid chemistry can be extended beyond energy and electronics to address pressing challenges in carbon management, providing a cost-effective and scalable pathway for designing new sorbents.Finally, my concluding remarks on the topics discussed in this dissertation are included in Chapter 6. The collective findings illustrate how amino acids can be uniquely positioned and engineered to serve in specialized roles requiring sustainability, biocompatibility, and multifunctionality. Moreover, the design strategies developed here provide a framework that may guide future research in materials engineering for advancing next-generation energy harvesting devices, bioelectronic platforms, and environmental remediation strategies. Key future directions I proposed here include the scalable manufacturing of bio-derived piezoelectric films, the development of polymer template and molecular interaction-guided approaches for precise crystal phase control, and the systematic optimization and advanced characterization of metal-amino acid frameworks for CO2 capture.
