摘要：
A coating for solar tubes may include 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 comprising 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.
