Novel integrative and bio-inspired synthetic strategies have emerged in the past decade as alternatives to conventional polymer processing and soft chemistry routes developed in the 1980s. The presentation will give an overview of the activities carried out at the EPFL to produce graded and hybrid organic/inorganic architectures hierarchically organized in terms of structure and functions [1]. Applications examples will include light-trapping encapsulation materials for thin film solar cells [2] and bio-inspired functionally graded nanocomposites employing magnetic field gradients [3] as hard and low-stress coatings, graded permittivity insulators and antibacterial surfaces.

Yves Leterrier holds a PhD in Materials Science and Engineering (INPL, F) and was a research associate at NIST (USA). He joined EPFL in 1993 and is a faculty member of the Materials Science Institute. His research work is devoted to thin films, multifunctional polymer nanocomposites and hybrid organic/inorganic materials. Focus is on fundamentals of surface and interfacial phenomena in view of cost-effective processes for flexible electronics, biotechnologies and renewable energy applications. Yves has authored more than 250 technical papers and has been invited to 50 conferences and institutes worldwide.
