Analytical Studies of Structure and Stability of Silver Nanoparticles in Layer-by-Layer Deposited Polyelectrolyte Films Dissertation zur Erlangung des Grades Doktor-Ingenieurin der Fakultät für Maschinenbau der Ruhr-Universität Bochum von Haybat Itani aus Beirut, Lebanon Bochum (2010) Dissertation eingereicht am: 28.04.2010 Tag der mündlichen Prüfung: 02.06.2010 Erster Referent: Prof. Dr. Gunther Eggeler Zweiter Referent: Prof. Dr. Guido Grundmeier Doctoral Thesis Haybat Itani Abstract The deposition of polymer films with incorporated metal or oxide nanoparticles lead to new functional properties. Properties such as electronic conductivity, hardness, magnetism, metal-ion release or optical activity etc. can be adjusted by choosing the right combination of metal nanocluster/polymer matrix and density of particles in the matrix. The in-situ formation of Ag-nanoparticles in layer-by-layer (LbL) deposited polyelectrolyte (PE) multilayers is an effective way to form multifunctional composite films that has many applications like increase of corrosion resistance, excellent formability and Ag-release for antibacterial properties.
