Fabrication of Porous PDMS/Au Composites for Solar-based Thermoelectric Power Generation |
| 초록 |
Metal nanoparticles absorb photons at certain wavelengths by localized surface plasmon resonance (LSPR) phenomenon and have photothermal properties that generate heat around nanoparticles. The heat generated by photothermal properties can be applied to many chemical systems including thermoelectric generator. Recently, significant efforts have been devoted to fabricating broadband light absorbers to improve their photothermal efficiency. In this study, we demonstrate a simple in-situ synthesis method for gold nanoparticles on porous polydimethylsiloxane (PDMS) as a light absorber. Porous PDMS elastomers were prepared by the well-known sugar template method and subsequently immersed in the solution of gold chloride (HAuCl4) for the in-situ synthesis of Au nanoparticles. Finally, the prepared PDMS composite was irradiated with a stimulated sun light to induce photothermal conversion, and the generated heat was applied to a thermoelectric device for power generation. |
