“…Furthermore, SRW-TC and SRW exhibited high UV absorption ability (Figure S6), mainly due to the residual phenylpropane and phenolic hydroxyl groups in WS and carbonyl groups, 61 which enabled the SRW-TC to be potential engineering materials for shielding humans and the living environment from the adverse impact of solar radiation. 62,63 For pure vitrimers, the high transmittance and low haze might compromise privacy (Figure S7). Fortunately, the SRW-TC and SRW displayed high haze of 99.67% and 92.32% (Figure 2g), respectively, ensuring indoor privacy security, and their high light capture capability and long capture duration contributed to achieving enhanced discharge power output in light regulation and energy storage systems.…”

Stimuli-responsive materials exhibit huge potential in sensors, actuators, and electronics; however, their further development for reinforcement, visualization, and biomassincorporation remains challenging. Herein, based on the impregnation of thermochromic microcapsule (TCM)-doped dynamic covalent vitrimers, a programmable shape-color dualresponsive wood (SRW-TC) was demonstrated with robust anisotropic structures and exchangeable covalent adaptable networks. Under mild conditions, the resultant SRW-TC displays feasible shape memorability and programmability, resulting from the rigidity−flexibility shift induced by the glass-transition temperature (34.99 °C) and transesterification reaction triggered by the topology freezing transition temperature (149.62 °C). Furthermore, the obtained SRW-TC possesses satisfactory mechanical performance (tensile strength of 45.70 MPa), thermal insulation (thermal conductivity of 0.27 W/m K), anisotropic light management, and benign optical properties (transmittance of 51.73% and haze of 99.67% at 800 nm). Importantly, the incorporation of compatible TCM enables SRW-TC to visualize shape memory feasibility and rigidity/flexibility switching and respond to the external thermal stimulus through the thermalinduced shape−color synchronous dual-responsiveness, which successfully demonstrates the applications of sensing temperature, grasping objects, encrypting/decoding icon messages, and so on. The proposed facile and highly effective strategy could serve as a guideline for developing high-performance multifunctional wood composite with promising intelligent applications in performance visualization, environmental sensing, materials interactivity, information dualencryption, local precision shape and color regulation, etc.

“…In Fig. 2(a), a typical ber structure was observed, and a large number of gaps and cavities between the ber structures were observed (Jiang et al 2023). Furthermore, due to the in uence of hydrophilic groups on the ber surface, the paper surface exhibited extremely strong wettability.…”

“…Additionally, the ≡ Si-OH group on the surface of the paper was reduced after PDMS modi cation. Thus, during the drying process, the hydrophobic ≡ Si-CH 3 group migrated spontaneously to the surface of the paper, making the surface structure of the paper hydrophobic (Jiang et al 2023). The microscopic roughness of the paper surface and the hydrophobic action of the PDMS made the paper appear superhydrophobic.…”

The water absorption and flammability of paper pose significant challenges for its long-term effectiveness. In addressing these concerns, a paper modification strategy was proposed that synergistically incorporated superhydrophobicity and flame retardancy. This approach involved the formation of a micro or nano-level rough structure on the paper surface through sodium silicate modification. Subsequent modification with polydimethylsiloxane (PDMS) resulted in a functional paper, exhibiting excellent superhydrophobic properties. The water contact angle (WCA) and sliding angle (SA) of the modified paper reached 153.5° and 9°, respectively, exhibiting excellent self-cleaning ability and wear resistance. The results from TG–DTG analysis and cone calorimeter tests indicated that the superhydrophobic paper exhibited remarkable thermal stability and flame-retardant properties. These properties contributed to enhancing the safety of products during application. The comprehensive improvement in paper properties, including its superhydrophobicity, flame retardancy, and thermal stability, holds significant implications for expanding its application range and enhancing its overall utility.
