A solar membrane distillation apparatus includes a housing comprising a light transmitting wall. A solar distillation membrane is positioned in the housing to receive solar radiation transmitted through the light transmitting wall. The solar distillation membrane includes a porous graphitic foam and a coating of a hydrophobic composition on the surface and pores of the graphitic foam. A water chamber within the housing is provided for retaining water adjacent to the solar distillation membrane. A vapor chamber is provided for collecting water vapor distilling through the solar distillation membrane. A condenser is provided for condensing distilled water vapor from the vapor chamber into liquid water. A separation membrane and a method of solar distillation are also disclosed.
A solar membrane distillation apparatus, comprising:
A separation membrane, comprising a graphitic foam and a surface coating of a hydrophobic composition on the surface and pores of the graphitic foam, the surface of the graphitic foam being superhydrophobic, wherein the hydrophobic composition is at least one selected from the group consisting of fluorosilanes, linear alkyl-silanes, branched alkyl-silanes, aromatic-silanes, fluorinated alkyl-silanes, dialkyl-silanes, carbon nanotubes, and carbon soot, and wherein the fluorosilane comprises the decomposition reaction product of heptadecafluoro-1,1,2,2-tetrahydrodecyl) trichlorosilane.
A method of solar distillation, comprising the steps of:
