The platinum nanoparticles (PtNPs) are very interesting for variety nano-scale science and electrocatalyst. Especially PtNPs are used to electrocatalyst for fuel-cell. In this study, we formed PtNPs in polyelectrolyte multilayer. These polyelectrolyte multilayers are composed of electrostatic force and hydrogen bonding. PAH and PAA multilayer film is formed by electrostatic force. Than PVP and PAA multilayer is formed by hydrogen bonding. These polyelectrolyte multilayers are based on layer-by-layer process. PVP embedded in PAH/PAA multilayer, which is similar to sandwich form. It is effective to increased chemical functional groups in sandwich form multilayer. We observed synthesis of PtNPs in polyelectrolyte multilayer by TEM, EDS. |
