Facile and green fabrication of flame-retardant Ti3C2Tx MXene networks for ultrafast, reusable and weather-resistant fire warning

Hierarchically structured polyvinylidene fluoride core‐shell composite yarn based on electrospinning coating method to improve piezoelectricity

“…In fact, when wrapping the second layer of PVDF piezoelectric nanofibers, the contact between the interfaces is very close since the size of the nanofibers are so thin that they wrapped the Ag NPs well in the process of rotating and twisting. Benefit from this tight structure, the final signal output of the composite yarn can keep stable 37 …”

“…Benefit from this tight structure, the final signal output of the composite yarn can keep stable. 37 Figure 4 shows the distribution of Ag NPs. When the content of silver-plated is 2% the distribution of Ag NPs is uniform while the other content is not.…”

Moisture-resistant MXene-sodium alginate sponges with sustained superhydrophobicity for monitoring human activities

“…The higher-performance piezoresistive pressure sensors often rely on the exploration of microstructures (e.g., porous or hollow [4,5], micropyramidal [6,7], or interlocked microstructure [8,9]) and/or functional materials (e.g., graphene [10], MXene [11,12], carbon nanotubes [13,14], metal nanostructure [15], carbon black [16], and conducting polymers [17]). MXene is a promising candidate for advanced pressure sensors due to its 2D structure, high electrical conductivity, hydrophilic surface, and ease of processing, and thus can be utilized in the strain sensor, humidity sensor, fire warning sensor et al [18][19][20][21]. However, the hydrophilic surface was easily influenced by moisture and hampered electron transport, resulting in an increase in electrical resistance [22,23].…”

“…In order to avoid electronic sensing interference and maintain service life, superhydrophobic modification has been proposed to minimize the water interference for the wearable sensor [25][26][27][28][29]. Few contact area exists between the water droplets and superhydrophobic surface, it is difficult for water to permeate into the conductive layer of the sensor [21,30]. Many works exsit for superhydrophobic MXene, MXene/alginate composites, MXene with Joule heating, and MXene for human activities monitoring.…”

Facile Fabrication of Graphene Oxide Nanoribbon-Based Nanocomposite Papers with Different Oxidation Degrees and Morphologies for Tunable Fire-Warning Response

“…To address the above issues, novel and complementary fire-warning materials and sensors have been developed over several years. Typically, the temperature-responsive resistance transition of various nano-fillers, e.g., graphene oxide (GO) [7][8][9][10][11][12][13][14], carbon nanotube (CNT) [15], and MXene [16], has been widely used to construct sensitive fire-warning sensors. Among them, GO-based fire-warning materials with sensitive flame detection and fire early-warning response have attractive considerable research interest.…”
