Microwave-assisted synthesis presents a promising method for enhancing the formation of nanocomposites due to its rapid heating and uniform energy distribution. In this study, we successfully fabricated polyethersulfone–zinc-oxide (PES-ZnO) nanocomposite membranes by exposing PES/ZnCl2/DMF dope solutions microwave radiation. Before synthesizing membranes, zinc-oxide nanoparticles (ZnO-NPs) were optimized in an organic phase using radiation ensure effective nanoparticle formation. The ZnO-NPs DMF solvent was validated through UV–Vis spectroscopy, X-ray diffraction (XRD), Dynamic Light Scattering (DLS). We examined surface morphology roughness PES-ZnO Atomic Force Microscopy (AFM) Scanning Electron (SEM). Moreover, assessed membranes’ hydrophilicity, permeability, physicochemical properties contact-angle measurements, pure water flux tests, uptake assessments, porosity tests. Energy-dispersive spectroscopy (EDS) (XRD) verified successful integration ZnO into membrane matrix. results indicate that including significantly improves membrane’s permeability hydrophilicity. exhibited high dye rejection efficiency, with facilitating photocatalytic self-cleaning properties. Antibacterial tests also demonstrated substantial inhibition common bacteria, suggesting enhanced resistance biofouling.

In order to efficiently exploit solar-thermal energy, it is essential develop form-stable phase-change material (PCM) composites simultaneously with superior storage efficiency, excellent flame retardancy, and improved thermal conductivity. Herein, phytic acid (PA)-modified, zinc oxide-deposited, surface-carbonized delignified woods (PZCDWs) were constructed by alkaline boiling, PA modification, ZnO deposition, surface carbonization. Then, novel PCMs (PZPCMs) conductivity fabricated impregnating n-docosane into PZCDWs under vacuum. The PZCDW aerogels can well support the overcome liquid leakage owing their tension strong capillary force. Differential scanning calorimetry results showed that PZPCMs possessed encapsulation yield high enthalpy (185.2-213.1 J/g). Decorating wood carbonization deposition significantly conversion efficiency (up 86.2%) (193.3% increased) of PCM composites. Furthermore, introduction PZPCMs, peak heat release rate total decreased considerably, indicating enhanced retardancy PZPCMs. conclusion, renewable wood-based demonstrate promising potential in solar energy harnessing modulation technologies.
