“…Because of their rich surface chemistry and high mechanical properties [22][23][24][25], twodimensional (2D) transition metal carbide/nitride/carbonitride (MXene) sheets have been intensively and extensively reported as nanofillers to improve the mechanical performances of SR and chemical resistances of P84 copolyimide [26,27]. However, there has been no investigation related to MXene/NR in the chemical protective field to date.…”

Rubbers are extensively applied in chemical protective clothing (CPC) due to their eye-catching anti-penetration of chemicals. However, their impermeability, particularly that of natural rubber (NR), is unsatisfactory. In this work, we demonstrate the facile construction of Ti3C2Tx MXene/NR interface using a plant-scale and feasible method combining latex mixing, emulsion flocculation, and flat-plate vulcanisation. The above crafts achieved a homogeneous dispersion of Ti3C2Tx MXene in the NR matrix in a single layer, thereby constructing a strong interfacial interaction between Ti3C2Tx MXene and NR, which induced the formation of a robust three-dimensional (3D) network in the composite. The anti-swelling capacity of the 3D cross-linked network structure and the layered structure of Ti3C2Tx MXene effectively prolonged the permeation path of toxic chemicals. Compared with pure NR, the nanocomposite with 1 wt% of Ti3C2Tx MXene showed substantially enhanced breakthrough times of toluene, dichloromethane, and concentrated sulfuric acid (increased by 140%, 178.6%, and 92.5%, respectively). Furthermore, its tensile strength, elongation at break, and shore hardness increased by 7.847 MPa, 194%, and 12 HA, respectively. Taken together with the satisfactory anti-permeability, tensile strength, elongation at break, and shore hardness, the resulting Ti3C2Tx MXene/NR nanocomposites hold promise for application to long-term and high-strength CPC in the chemical industry and military fields.

For the drawbacks of phase change materials such as poor shape stability and weak solar‐thermal conversion ability, a rotunda‐shaped carboxymethylcellulose/carbon nanotube aerogel (CA) with three‐dimensional network was constructed by freeze casting with a special mold, and then impregnated with polyethylene glycol (PEG) in this work. The PEG/CA had an enthalpy of 183.21 J/g, and a thermal conductivity of 0.324 W•m‐1K‐1, which was 57% higher than the pure PEG. The ability of PEG/CA to convert solar energy to thermal energy was a positive correlation between the inclusion of CNTs and the composite material's thermal conductivity. Under simulated sunlight, its solar‐thermal conversion efficiency reaches 94.41%, and after 10 min of irradiation, the surface temperature can reach 65 ℃ and the internal temperature can reach 44.67 ℃. This rotunda‐shaped PEG/CA is promising for the efficient use of renewable solar energy due to its strong solar‐thermal conversion and thermal storage capabilities.
