As a remarkable multifunctional material, ferroferric oxide (Fe3O4) exhibits considerable potential for applications in many fields, such as energy storage and conversion technologies. However, the poor electronic and ionic conductivities of classical Fe3O4 restricts its application. To address this challenge, Fe3O4 nanoparticles are combined with graphene oxide (GO) via a typical hydrothermal method, followed by a conductive wrapping using poly(3,4-ethylenedioxythiophene):poly(styrene sulfonic sulfonate) (PEDOT:PSS) for the fabrication of composite films. Upon acid treatment, a highly conductive porous Fe3O4@RGO/PEDOT:PSS hybrid is successfully constructed, and each component exerts its action that effectively facilitates the electron transfer and subsequent performance improvement. Specifically, the Fe3O4@RGO/PEDOT:PSS porous film achieves a high specific capacitance of 244.7 F g−1 at a current of 1 A g−1. Furthermore, due to the facial fabrication of the highly conductive networks, the free-standing film exhibits potential advantages in flexible thermoelectric (TE) materials. Notably, such a hybrid film shows a high electric conductivity (σ) of 507.56 S cm−1, a three times greater value than the Fe3O4@RGO component, and achieves an optimized Seebeck coefficient (S) of 13.29 μV K−1 at room temperature. This work provides a novel route for the synthesis of Fe3O4@RGO/PEDOT:PSS multifunctional films that possess promising applications in energy storage and conversion.

Developing multifunctional construction materials with advanced functionalities and excellent mechanical toughness remains a significant challenge within the field of civil engineering. Herein, a scalable and cost‐effective approach for fabricating versatile cement‐based composites is introduced. This is achieved by pre‐embedding a 3D‐printed conductive lattice framework (LF) into cement pastes with the incorporation of carbon black (CB). LFs contribute significantly to the flexural extension of the composite structure and when combined with CB, they substantially improve the conductivity of the matrix, enabling its self‐sensing applications. Moreover, the obtained conductivity enables the application of electrochemical deposition techniques for in situ polymerization and deposition of polypyrrole (PPy) onto the composite surface. PPy coatings further endow the cement‐based composites with excellent electrothermal and electrochemical performance. For instance, applying a direct current voltage of 18 V for 10 min results in a temperature increase exceeding 45 °C, indicating promising de‐icing capabilities. When assembled as a supercapacitor, it exhibits an outstanding energy density, reaching 61.7 µWh cm−2 at a power density of 150 µW cm−2 and demonstrating its potential for energy storage application in the construction sector. In conclusion, this study introduces an innovative strategy for the advancement of intelligent and multifunctional cement‐based construction materials, emphasizing the importance of multifunctionality in modern construction practices.
