In this work, graphene and BaTiO3 are used to synergistically facilitate the self-assembly of the β-phase that is known to induce the piezoelectric properties of the polyvinylidene fluoride (PVDF). This leads to a PVDF/graphene-BaTiO3 nanocomposite with a unique capability of integrating Phra Phrom-like four functions into one single asymmetric membrane: i) solar evaporation, ii) power generation, iii) piezo-photodegradation, and iv) self-cleaning/monitoring for environmental remediation and resources regeneration. The high heat accumulation capability and piezoelectric performance of the membrane enable it to simultaneously achieve a water production rate of 0.99 kgm−2h−1, in compliance with WHO standards, and a maximum power output of 5.73 Wm−2 in simulated natural environments. Upon subjecting the membranes to environmental cleaning, they not only show a 93% dye degradation rate due to the synergistic effect of piezoelectricity and photocatalysis but also resolve the membrane fouling issue, exhibiting ≈200% resistance change compared to the static state. The successful integration of these four functions into one membrane shows the great potential of this work toward a more sustainable and viable water and energy production approach.piezo-photodegradation | power generation | self-cleaning/monitoring | solar evaporator | β-PVDF/Graphene/BaTiO 3[SDGs]SDG6[SDGs]SDG7[SDGs]SDG11journal article10.1002/adfm.2023083212-s2.0-85175159039https://api.elsevier.com/content/abstract/scopus_id/85175159039
