Two-dimensional crystals (2DCs) can impact remarkably diverse fields, from information and photonic technologies to healthcare, and from flexible electronics to energy storage and environmental remediation.
However, widespread deployment remains constrained by the simultaneous requirement for atomic-scale control and high-volume, eco-friendly manufacturing. This talk illustrates how complementary fabrication routes – chemical vapor deposition (CVD) and liquid-phase exfoliation (LPE) – translate fundamental material properties into reproducible, application-ready platforms across distinct technological domains. From an atomic-scale perspective, a combination of optimized CVD processes and targeted surface functionalization has been used to grow and integrate MoSe2 switching layers into crossbar memristors operating in the sub-1 V regime. Leveraging similar structural control, crystallinity and defect density were tuned to induce room-temperature emission features in hBN consistent with single-photon sources. In parallel, graphene surface engineering was used to build multipurpose bioelectronic platforms suitable for ultra-sensitive biosensing and neuroregenerative biointerfaces. From a manufacturing perspective, high-throughput LPE in green solvents was developed to preserve dispersion stability while maximizing exfoliation efficiency. As-prepared dispersions were used to fabricate 2DC-based nanofiltration membranes with selective ion-sieving performance. Scalability was further increased via a continuous hybrid LPE process in water at industrially relevant rates, enabling the formulation of printable pastes for flexible microsupercapacitors and sensors. Using the same processing framework, conductive nanocarbon–
elastomer composites were produced to realize textile-integrated supercapacitors and wearable strain sensors with robust long-term stability.
