Abstract | Emerging smart fire alarm sensors (FAS) are crucial for monitoring fire hazards and have garnered increasing attention in fire safety field. However, developing low-cost yet high-performance FAS materials with mechanical flexibility, environmental tolerance, flame retardancy, and reliable fire warning capabilities via a simple and sustainable approach remains a major challenge. Here, we report a simple yet effective tannic acid (TA)-assisted mechanochemical exfoliation method for producing few-layer modified molybdenum disulfide (TA-MoS2) nanosheets with excellent water dispersibility and long-term storage stability. Besides, the method's universality was further validated with other transition metal dichalcogenides (TMDs), including MoSe2, WSe2, and WS2. By integrating one-dimensional (1D) phosphorylated-cellulose nanofibrils (P-CNFs) with two-dimensional (2D) TA-MoS2 nanosheets, we fabricated P-CNFs/TA-MoS2 nanocomposite papers with a hierarchical biomimetic structure. The optimized paper demonstrated exceptional mechanical flexibility and strength (∼118 MPa), solvent resistance, and flame retardancy. Notably, it achieved a rapid fire alarm response (<3 s) and reliable cyclic fire warning performance. These outstanding properties make such MoS2-based hybrid network a promising candidate for FAS materials in fire safety and protection. Furthermore, the TA-TMDs synthesized via this strategy hold significant potential in electronics, biomedicine, catalysis, and energy sectors. |
