Flexible pressure sensors as wearable electronic devices to monitor human health have attracted significant attention. Herein, a simple and effective carbonization-free method is proposed to prepare a compressible and conductive reduced graphene oxide (rGO)–modified plant fiber sponge (defined as rGO-PFS). The introduced GO can not only coat on the...
Biomimetic flexible electronics for E‐skin have received increasing attention, due to their ability to sense various movements. However, the development of smart skin‐mimic material remains a challenge. Here, a simple and effective approach is reported to fabricate super‐tough, stretchable, and self‐healing conductive hydrogel consisting of polyvin...
Sustainable biomass materials are promising for low-cost wearable piezoresistive pressure sensors, but these devices are still produced with time-consuming manufacturing processes and normally display low sensitivity and poor mechanical stability at low-pressure regimes. Here, an aqueous MXene ink obtained by simply ball-milling is developed as a c...
Rapid and efficient clean-up of viscous crude oil spills is still a global challenge due to its high viscous and poor flowability at room temperature. The hydrophobic/oleophilic absorbents with three-dimensional porous structure have been considered as a promising candidate to handle oil spills. However, they still have limited application in recov...
Renewable and biodegradable plant fiber sponges (PFS) can be used as substitutes for some petroleum-based polymers. They could make a positive contribution to the daily carbon footprint. However, the natural fire hazard of PFS could result in a severe safety concern and restrict their application. Herein, a highly thermo-conductive hexagonal boron...
Increasing environmental problems caused by the emission of crude oil, petroleum products, and toxic organic solvents have threatened ecosystems and human health. Renewable and eco-friendly natural materials are considered as the most promising absorbents for removing oils and organic solvents from water. In this work, a hydrophobic plant fiber spo...

... Sensors are devices measuring physical or chemical phenomenon, acting as a transducer for different signals [68][69][70][71][72][73]. Sensors can measure the output of the phenomenon in an optical or electrical signal, which in turn processed and displayed, such as thermocouples (temperature), humidity, light resistors, chemical sensors (e.g., gas sensor) [13,74,75], and pressure sensors [76][77][78]. ...

... Water molecules interconnect via hydrogen bonds to form a water network, while the polymer forms a three-dimensional network structure through crosslinking, serving as the backbone of the hydrogel. This structure enables hydrogels to adsorb a significant amount of water molecules and affects many of their unique properties, such as their excellent elasticity and flexibility, enabling them to withstand large deformations without breaking easily [14][15][16][17]. Many natural hydrogels possess good biocompatibility, making them applicable in the biomedical field, for instance, in the fabrication of biosensors for wearable devices. ...

... Sponge, a porous material frequently encountered in daily settings, is recognized for its high porosity and significant internal surface area, offering promising applications in the field of pressure sensing [109]. Chen et al. [94] developed a compressible and conductive 3D MXene plant fiber sponge (MX-PFS) (Figure 13a). Tests revealed that the MX-PFS@PDMS sensor based on MX-PFS achieved sensitivity responses of 89.14/kPa and 435.06/kPa within pressure ranges of 0.02-2 kPa and 2-10 kPa, respectively. ...

... Meanwhile, the oil recovery rate was always around 90%. Excitingly, after 10 cycles, GCB-MS sponges still exhibited good water resistance with WCA of 144.1 • (Fig. 7h). Compared with other sorbent materials that have been reported [14,23,29,30,36,37,40,43,5,6], the sorption capacity of GCB-MS also showed an extremely superior advantage (Fig. 7i). These results confirm the huge potential of GCB-MS for actual offshore oil spill remediation. ...
... This unique porous structure with fibrils interconnected skeleton is mainly formed by introducing the bubbles during the physical foaming. When the water evaporated in the drying process, the PF settled around the bubbles retain a hierarchical porous structure, which may be beneficial for crude oil adsorption because of its low mass transfer resistance and strong capillary effect (Chen et al., 2018(Chen et al., , 2022Z. Liu et al., 2021). ...

... Currently, superhydrophobic or superoleophilic sorbents are commonly artificially synthesized by modifying the chemical composition of materials with low surface energy or constructing a rough topography. According to the type of substrate, they are classified into fiber materials [15], aerogel materials [16], resin materials [17], etc. In most cases, these technical materials are fabricated as polymeric sponges [18][19][20], specially coated metal meshes [21][22][23], or metal-coated fabrics [5] by various chemical methods. ...
