This contribution reports on the structural, optical and morphological properties of nanostructured flexible solar-thermal selective absorber composites for low temperature applications. The candidate material in the system is consisting of electrodeposited nickel nano-cylinders embedded in track-etched polyethylene terephthalate host membrane of pore sizes ranging between 0.3-0.8 Ī¼m supported by conductive nickel thin film of about 0.5 Ī¼m. The tubular and metallic structure of the nickel nano-cylinders within the insulator polymeric host forms a typical ceramic-metal nano-composite ā??Cermetā?. The produced material were characterized by the following characterization techniques: X-ray diffraction (XRD) for structural characterization to determine preferred orientation, crystallographic structure, and grain size of the materials; Scanning electron microscopy (SEM) to determine surface morphology, particle size, and visual imaging of distribution of structures on the surface of the substrate; Atomic force microscopy (AFM) to characterize surface roughness, surface morphology, and film thickness, and UV-vis-NIR spectrophotometer to measure the reflectance, then to determine solar absorption.
