“…Recently, it has been reported that the designed wood surfaces possessing photothermal effects could enhance the durability and also endow the materials with anti-icing, oil-water separation/crude oil recovery, self-healing, and UV shielding properties. [28][29][30][31][32] The recent progress of superhydrophobic surfaces has greatly promoted the emerging applications of wood products, especially in energy storage and conversion elds, such as electrocatalysis and nanogenerators.…”

It is highly desirable to develop polydimethylsiloxane (PDMS) elastomers with high self-healing efficiency and excellent mechanical properties. However, most self-healable materials reported to date still take several hours to self-heal and improving the self-healing property often comes at the expense of mechanical properties. Herein, a simple design strategy of dual reversible network nanoarchitectonics is reported for constructing ultrafast light-controlled healable (40 s) and tough (≈7.2 MJ m −3 ) PDMS-based composite elastomers. The rupture reconstruction of dynamic bonds and the reinforcement effect of carbon nanotubes (10 wt %) endowed our composite elastomer with excellent fracture toughness that originated from a good yield strength (≈1.1 MPa) and stretchability (≈882%). Moreover, carbon nanotubes can quickly and directly heat the damaged area of the composite to achieve its ultrafast repair with the assistance of dynamic polymer/filler interfacial interaction, greatly shortening the self-healing time (12 h). The self-healing performance is superior to that of reported self-healable PDMS-based materials. This novel strategy and the as-prepared supramolecular elastomer can inspire further various practical applications, such as remote anti-icing/ deicing materials.

The application of self-healing polymers in corrosion protection is often limited by their slow and nonautonomous healing ability and poor long-term durability. In this paper, we propose a double-layered transfer self-healing coating constructed by soft and rigid polymer layers. The soft polymer has a fast self-healing rate of 10 min to repair, which was found to accelerate the self-healing of the upper rigid layer. The rigid polymer provided relatively high barrier ability while preserving certain self-healing ability owing to the shear-thinning effect. In this way, the double-layered coating combined rapid self-healing (∼1 h) and high impedance modulus |Z| f-0.01 Hz of 2.58 × 10 10 Ω•cm 2 . Furthermore, the introduction of pyridine groups in B-PEA and polyacrylate-graf ted-polydimethylsiloxane (PEA-g-PDMS) induced the Fe ionresponsive ability and shortened the self-healing time to 40 min (100 ppm Fe). Finally, barrier and anode sacrificed layers were introduced to produce multilayered architecture with active/ passive anticorrosion performance. In the presence of scratches, the |Z| f-0.01 Hz can be preserved at 1.03 × 10 10 Ω•cm 2 after 200 days. The created anticorrosive coating technology combines long-term durability with room temperature autonomous rapid self-healing capability, providing a broad prospect for anticorrosive applications.
