| Sumario: | <p id="p1">Integrating carbon nanotubes (CNT) and renewable biopolymers for producing solar-driven photothermal conversion materials exhibits unique advantages in cleanliness and controllability and represents a sustainable trend. However, such composites suffered from complex preparation processes, insufficient stability, leakage, photobleaching, and poor thermal conductivity. In harsh environments, corrosion resistance, mechanical properties, and photothermal conversion also face severe challenges. Here, we construct a CNT/natural polymer composite using carbohydrazide (CDH) as a block to covalent with sodium carboxymethyl cellulose (CMC) to prepare CMC-CDH networks, then combined with CNT to fabricate CMC-CDH-CNT film. As-prepared CMC-CDH-CNT film possessed extreme stability in harsh conditions and exhibited a high strength of 458.8 MPa, Young’s modulus of 18.8 GPa, and toughness of 13.3 MJ m<sup>−3</sup>. Besides, the CMC-CDH-CNT film also revealed an excellent photothermal conversion efficiency of 54.8%. CMC-CDH-CNT film showed good corrosion resistance, which led it to have high potential application in severe environments.</p> |
