Solar vapour generation is an efficient way to harvest the solar power for the purification of polluted or saline water. However, well-known solar vapour generation systems were complex and expensive while they have not enough efficiency. Therefore, we suggest the poly pyrrole coated hierarchical porous polydimethylsiloxane (PDMS) which have high efficiency and excellent cost benefit. The PDMS is used as main material due to excellent durability and cost advantage. And then, we manufacture hierarchical open porous structure via simple etching technique using salt and water. As advantage of this hierarchical structure, the membrane can pull up water and it could extremely increase the efficiency of solar vapour generation. Furthermore, we coated poly pyrrole on the surface of the PDMS membrane to keep the solar power. As a result, poly pyrrole coated hierarchical porous PDMS has high efficiency and simple method with low cost. |
