<title>Abstract</title> <p> The rapid growth of power electronics, electric mobility, data centers, renewable energy systems, and high-density computing has intensified the need for sustainable thermal management solutions. Thermal interface materials (TIMs) play a critical role in reducing interfacial thermal resistance between heat-generating components and heat dissipation units, thereby improving device efficiency, operational reliability, and lifecycle energy consumption. Conventional polymer-based TIMs, however, suffer from limited thermal conductivity, pump-out, dry-out, thermal degradation, and reduced long-term sustainability. This paper reviews emerging paradigms in advanced TIM engineering based on metallic nanostructures, phase change materials (PCMs), and hybrid architectures designed for next-generation energy-efficient systems. Particular emphasis is placed on the patented <bold>Chakravardhan 22 (CV22)**</bold> architecture, which represents a transition from material-centric formulations to architecture-driven interface engineering. In this system, interconnected metallic nanostructures provide continuous thermal transport pathways, while compliant or phase-change media ensure conformal contact, transient heat buffering, and mechanical stability. The analysis demonstrates that nanostructure-enabled hybrid TIMs can significantly reduce thermal resistance, enhance sustained power handling, suppress throttling losses, and extend device service life. Such improvements are directly relevant to renewable and sustainable energy systems, where thermal efficiency strongly affects battery packs, power converters, photovoltaic electronics, electric vehicles, and smart infrastructure. Future opportunities include recyclable TIMs, low-carbon manufacturing, AI-assisted materials design, and circular-economy compatible thermal management materials. </p>
