“…Moreover, the photocatalytic foam could be cut to any desired size, and for refreshing use ( Figure a,b). XRD patterns showed three primary components of EVA foam, [ 18,21,22 ] P25 TiO 2 catalyst, and CaCO 3 filler in the photocatalytic foam. The crystalline structure of TiO 2 remained changed during the foaming processes.…”

“…More efforts must be paid to searching for adequate foaming materials. Inspired by the highly transparent ethylene‐vinyl acetate (EVA) film in solar cell package, TiO 2 thermally cross‐linked on EVA plastic pellets as a floating photocatalyst, [ 18 ] and durable EVA foam in shoe insole, we thought that this kind of polymer is adequate for photocatalytic foam. EVA foams with closed‐cell foam structure show features of buoyancy, high mechanical strength with resilience, heat insulation, water/moisture resistance (antifouling), and long‐term durability (nonyellowing), making them a promising candidate for photocatalytic foam fabrication.…”

Semiconductor photocatalysis has been a promising candidate for micropollutant degradation in environmental remediation. In the past 50 years, TiO2 nanomaterials‐based photocatalytic devices have been practically applied to ex‐situ sewage treatment. This work promotes the practical photocatalytic application of TiO2 nanomaterials by successfully fabricating a scalable and refreshable photocatalytic foam. The fabrication is done by firmly immobilizing catalyst nanoparticles on ethylene‐vinyl acetate (EVA) foam. The immobilization replaces commonly used ZnO promoter by TiO2 catalyst nanoparticles in raw materials during industrial foaming production processes. The as‐fabricated photocatalytic foam exhibits excellent photocatalytic activity, stability, and refreshability in in‐situ micropollutant degradation.

“…Compared with polyethylene, the introduction of vinyl acetate monomer into EVA molecular chain greatly improves the flexibility and impact resistance. [ 50 ] Therefore, the prepared EE foam also has greater flexibility. As shown in Figure a, at low EG content, EE‐0 and EE‐4 can be easily folded twice without damaging the PCC.…”

The working electronic devices and batteries generate a lot of heat, if this heats not release quickly, it will not only have a great impact on the performance of the devices, but also cause certain safety hazards. The passive thermal management based on organic phase change materials (PCMs) stands out due to its excellent temperature regulation capability as well as the buffer protection capability for device overload. In view of these, a series of flexible EVA/EG@PW (EE@P) phase change composites (PCCs) with high thermal conductivity are prepared by efficiently constructing porous skeletons and thermal conductive pathways through sacrificial template method, and introducing paraffin wax (PW) by simple vacuum impregnation technique. The PCC exhibits high thermal conductivity (2.6 W m−1 K−1), high enthalpy (153.5 J g−1), and good flexibility. In addition, the PCC possesses excellent cycling stability and thermal stability. In practical application, the PCC shows good temperature control ability for LED and shows great potential application in the field of thermal management.
