- 요약There is significant demand across industries for lightweight, multifunctional materials capable of performing under different environmental conditions. As introduced in this dissertation, one promising class of such materials is lightweight structuraldamping films-based graphene oxide (GO), a relatively inexpensive and waterprocessable sister of graphene. The damping functionality is essential for protecting sensitive components from damage caused by vibrations and potentially impact. Interestingly, GO films overcome the limitations of traditional materials by providing both high stiffness and damping across wide temperature and humidity ranges. Simple processing renders these films electrically conductive, adding functionalities such as electromagnetic interference (EMI) shielding and lightning strike protection, which are particularly important for aerospace applications. As a result, GO films can eliminate the need for multiple materials in advanced structures, thus avoiding complex and potentially inefficient designs. This dissertation investigates the stress transfer and damping mechanisms in GObased films and composites, using experimental testing and numerical modeling. Using this new understanding, key structural modifications are applied to GO films, including the chemical reduction of GO to produce reduced graphene oxide (rGO), tuning of particle size and film packing, and reinforcement with carbon nanofibers (CNF). These strategies aim to enhance not only damping and stiffness but also electrical and mechanical performance. By correlating structural changes with functional improvements, this work advances the development of multifunctional structural damping films. Ultimately, such films could be integrated into conventional composites to enhance bulk properties, enabling more efficient and less constrained structural designs.
