Recent breakthroughs in nanocomposite technology have revolutionized our ability to probe and manipulate materials systems at the molecular level. This presentation highlights two seminal studies that exemplify this progress. First, we introduce a groundbreaking approach to make stretchable conductors combining the features of gold nanoparticles and polymers. Especially, we demonstrate the creation of stretchable nanoparticle conductors featuring self-organized conductive pathways. These materials combine high electrical conductivity with mechanical flexibility, offering transformative potential for wearable electronics and soft robotics. Building on this foundation of adaptive nanomaterials, the second study introduces reconfigurable chiroptical nanocomposites that transfer chirality from macroscopic to nanoscale dimensions. Further development of technology has been proven by energy storage devices. We recently demonstrated that iCOF/polymer composite can be an excellent all-solid-state electrolyte for LMBs. We demonstrated that composites comprising iCOFs and poly(ionic liquid) (PIL) all-solid-state electrolytes show an exceptional ionic conductivity up to 1.29 × 10−3 S cm−1 and a high Li+ transference number of > 0.80 at room temperature, outperforming liquid electrolytes. Notably, the Li metal full cells sustained 87% of the capacity after 800 cycles, meeting the industry standards. Together, these innovations underscore nanotechnology’s potential to revolutionize electronics, optics, and energy storage.
