Nanoscale properties. Nanocomposites. Gas-porosimetry: surface area and pore volume measurement (adsorption isotherms, BET and BJH models). Microscopies: optical, SEM, TEM, STM, AFM.
Dynamic Light Scattering, Z potential.
Introduction to thermal analysis. Thermogravimetry. Thermal properties of polymeric nanocomposites. Modulation temperature DSC. Thermal analysis of biological nanosystems (microDSC, ITC). Mechanical properties of nanocomposites. Statistical nanoindentation.
The course is aimed to evidence the potential of both classical and cutting-edge techniques, in the evaluation of the nanoscale properties. Starting from representative examples, the physico-chemical characteristics of the nanosystems will be introduced and the main techniques for the investigation of these properties will be presented.
In particular, the classroom lectures (3 cfu) will deal about the methods for the study of the structure, the surface area, the thermal and spectroscopic properties, the mechanical properties of both soft and hard nanostructured systems. In the laboratory activity (3 cfu), practical experiences will be performed on some of the presented instruments.
