Abstract: The present invention provides a solar absorber incorporated bilayer foam solar evaporator for seawater and wastewater purification including a plurality of solar absorbers partially incorporated into a porous polymer framework and partially forming a thermal insulation layer proximal to solar irradiation. In particular, low-cost commercially available B4C powders are embedded into a porous polymer foam in a one-pot method to form a scaffold of boron carbide bilayer foam (BCBF) with good hydrophilic wettability, heat-shielding, and solar-thermal conversion. The boron carbide bilayer foam (BCBF) of the present invention enables a high cost-performance seawater desalination and wastewater purification at a high evaporation rate of 2.8 kg/m2/h with 93% solar evaporation efficiency under 1 sun illumination (or 1 kW/m2). The present invention thereby provides an excellent and cost-effective solar evaporator tool for industrial-level water purification. Following the present method to prepare the BCBF solar evaporator, the fabrication cost can be as low as 3.6 $/m2.

Abstract: A coating for solar tubes has a porous absorbing layer that includes an absorbing black pigment material mixed with a porous binder having an open porosity, and a first protective layer having oxides applied on top of the porous absorbing layer. The first protective layer may penetrate to at least a portion of the open porosity. The first protective layer may include nanoparticles, to improve the filling of the pores. A second protective layer may be applied after the first layer, to improve the filling of the remaining gaps.
