PDMS(Polydimethylsiloxane) is the most common material as nature friendly material. We have used PDMS owing to its relatively simple, fast and low-cost fabrication. At the same time, some distinct characteristics associated with PDMS such as good flexibility, no toxicity, and excellent chemical durability. PDMS is hydrophobic material so that it could launching on the water and we used this property as solar to steam generation. We fabricate hierarchical porous PDMS through this brief method which is simple etching system 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. We manufactured PDMS as a black membrane by simple polymerization with iron chloride and pyrrole to poly pyrrole and this membrane could keep the power of sun. As a result, poly pyrrole coated hierarchical porous PDMS has high efficiency and simple method with low cost. |
