In this study, we present our findings from analyzing data contained in approximately 265,000 journal and patent publications the field of carbon nanotube (CNT)-related research spanning last two decades (2003 to 2023). The purpose study is identify extract prominent trends establish connections, such as those between materials applications. Using a natural language processing (NLP)-based analysis, have identified over 80 emerging concepts across three major categories (applications, materials, properties) CNTs, which presented "Trend Landscape" map. While early efforts appeared focus on synthesis techniques (including now well-established dominant technique chemical vapor deposition (CVD)), recent years has been driven by an increase interest CNT composites, especially involving other nanoscale MXene metal–organic frameworks (MOFs). High growth applications include use CNTs energy storage conversion technologies fuel cells, next-generation batteries, nanogenerators, sensors including wearable human motion sensors. Investment suggests commercial development variety industry types, semiconductors, energy, smaller extent biomedical industry. intent report serve useful guide researchers aid further exploration based

Flexible, Reliable, and Lightweight Multiwalled Carbon Nanotube/Polytetrafluoroethylene Membranes with Dual‐Nanofibrous Structure for Outstanding EMI Shielding and Multifunctional Applications

Small, Год журнала: 2024, Номер 20(24)

Опубликована: Янв. 4, 2024

In this study, lightweight, flexible, and environmentally robust dual-nanofibrous membranes made of carbon nanotube (CNT) polytetrafluoroethylene (PTFE) are fabricated using a novel shear-induced in situ fibrillation method for electromagnetic interference (EMI) shielding. The unique spiderweb-like network, constructed from fine CNTs PTFE fibrils, integrates the inherent characteristics these two materials to achieve high conductivity, superhydrophobicity, extraordinary chemical resistance. demonstrate EMI shielding effectiveness (SE) 25.7–42.2 dB at thickness range 100–520 µm normalized surface-specific SE can reach up 9931.1 dB·cm2·g−1, while maintaining reliability even under extremely harsh conditions. addition, distinct electrothermal photothermal conversion properties be achieved easily. Under stimulation modest electrical voltage (5 V) light power density (400 mW·cm−2), surface temperatures CNT/PTFE 135.1 147.8 °C, respectively. Moreover, exhibit swift, stable, highly efficient thermal capabilities, endowing them with self-heating de-icing performance. These versatile, breathable membranes, coupled their facile fabrication process, showcase tremendous application potential aerospace, Internet Things, wearable electronic equipment extreme environments.
