Main themes After a general introduction on nanosciences and nanotechnologies, the fabrication and characterisation techniques of organic thin films are presented. This part is also dedicated to the study of particular properties such as dewetting or self-assembly of monomolecular films for the functionalization of various surfaces. A second part is dedicated to "soft" nano-fabrication techniques, particularly "soft" nanolithography and nano-fabrication through self-assembly. The third part aims at sensitize students to the phenomena of phase separation in block copolymers. The various morphologies obtained in the solid state with di- and tri-block copolymers are discussed in more details. Phase separation is then discussed in the case of thin films or in a good solvent of one of the block (micellar structures). A special emphasis is placed on the recent applications in nanotechnology and the present state-of-the-art. In the fourth part, the synthesis, the properties and the applications of nanowires and nanotubes are presented. This part particularly describes the different techniques to fabricate such nanostructures with an accurate control of their size, geometry, composition and surface properties. Structures based on conjugated polymers are presented together with some of their applications in nano-electronics. The applications of these nanostructures in biomedicine are also discussed. The last part is dedicated to the presentation of the principles of scanning probe microscopies (STM and AFM) and of certain applications of these techniques in macromolecular nanotechnology: the use of scanning tunnelling spectroscopy for the characterisation of the electronic properties of conjugated polymers, the characterisation of block copolymers by phase detection microscopy, single molecule force spectroscopy, manipulation of atoms or molecules and nano-fabrication by SPM.
Aims The objective of this set of lectures is to introduce students to the main applications and functions of organic and polymer materials for micro- and nanotechnologies. The interdisciplinarity of the field will be specially emphasized, as well as recent applications in the fields of electronics, optics, biosensors, biomedicine, ... This course also aims at introducing some characterisation techniques especially suited for the study of the structure and of the properties of macromolecular nanostructures. At the end of their classes students are expected to be able: - to propose fabrication methods to realise a given nanostructure presenting specified properties (electrical, biochemical, optical,...); to compare and discuss their advantages and drawbacks; to propose characterisation techniques; - to propose methods for the (bio-)functionalization of surfaces; to compare and discuss their advantages and drawbacks; - to understand and apply the phase separation phenomenons in block copolymers in order to propose polymer nanomaterials for specified applications; - to understand the basic working principles of scanning probe microscopies; - to apply these techniques to characterise the structure/morphology and/or the properties of a given macromolecular nanostructure, or to fabricate a macromolecular nanostructure.
