The frequent occurrences of offshore oil spills have led to severe environmental contamination and ecological threats. However, traditional recovery methods pose issues such as high‐energy consumption, low absorption efficiency and secondary pollution. This work prepared a hydrophobic aerogel (P‐GO@CNTs‐9/ATP/SA) using sodium alginate, attapulgite and graphene oxide surface‐modified carbon nanotubes with superior solar/Joule heating ability. The water contact angle of this aerogel is approximately 147.5°. Moreover, this aerogel demonstrates stable and efficient photothermal conversion properties, reaching a surface temperature of 82.3 °C under one solar illumination (1 kW/m2). Furthermore, when applying a voltage of 10 V, the surface temperature of the P‐GO@CNTs‐9/ATP/SA aerogel reaches 170.4 °C, assisting photothermal conversion to enhance the fluidity of viscous oil, thereby conserving energy. Finally, we present a continuous absorption device utilizing P‐GO@CNTs‐9/ATP/SA as the primary component, enabling automatic switching between photothermal and electrothermal modes for the comprehensive and continuous treatment of oil spills. Due to the unique design, environmental friendliness and ideal absorption capacity, this approach offers a novel choice for recovery of oil spills, which is expected to further promote principles of sustainable development.

Localized foaming of polymers is promising to fabricate polymeric composite structures for applications in biomedical, aerospace, automotive, etc. However, the severe pyrolysis and carbonization of polymer chains during localized foaming may degrade the bulk strength. Herein, a mild localized foaming strategy is proposed to fabricate poly(lactic acid) (PLA) micro‐foams within dense PLA matrices using ultrafast lasers. The PLA substrates doped with graphene (Gr) and azodicarbonamide (AC) are developed for mild foaming. A picosecond laser is applied to pattern PLA micro‐foams on the PLA/Gr/AC substrates to fabricate porous/nonporous micro‐composite structures. The thermal behavior of the PLA/Gr/AC substrates is characterized to evaluate their capability in photothermal conversion and mild foaming during ultrafast laser pulses. To optimize the laser foaming process, the microstructure of the laser‐foamed PLA processed with different laser parameters is studied. It demonstrates that the oxidation of the functional groups dominates the side reactions on the PLA chains with slight variation in molecular weight during laser foaming, indicating that the PLA chains keep almost intact and mild localized foaming is realized. Furthermore, the developed technology is demonstrated for micro‐patterning and texturing, material toughness programming, and shape memory programming, showing promising applications for smart materials, metamaterials, micro‐robotics, and biological scaffolds.

Photothermal antibacterial composite membranes have a broad range of clinical applications such as wound dressing, drug delivery, and physiotherapy. However, existing photothermal antimicrobial films have limitations related to biosafety, stability, and degradability. Herein, we develop an environmentally‐friendly composite membrane with antibacterial properties, photothermal conversion capability, and facile processing. The composite membrane film is comprised of polylactic acid (PLA) with graphene (G) and is synthesized via melt co‐blending and hot pressing. We verify that graphene is uniformly dispersed in the PLA phase, and an antibacterial rate of 99.7% can be achieved by a PLA/G composite membrane with only 3.0 wt.% graphene added. Moreover, the obtained films exhibit efficient photothermal conversion, reaching thermal treatment temperatures (40–60°C) within 10 s and maintaining temperature stability for extended periods. Additionally, the composite fiber film exhibited a tensile strength of 3.5 cN/dtex and good hydrophobicity (>90° contact angle). The combination of antibacterial properties, efficient photothermal conversion, noninfiltration, high strength, hydrophobicity, and mechanical stability, along with the inherent degradability of PLA and the scalability of the synthesis process for mass production, offer broad application prospects for PLA‐based composite materials.
