Missions

A postdoctoral fellow is sought to work on an interdisciplinary project targeting the use of block copolymer materials for the development of 3D functional structures. Indeed perfectly ordered microstructures with nanometrically defined periodicity offer promising opportunities in microelectronic applications and nanotechnologies for the production of high-density magnetic storage media, plasmonic based devices and advanced CMOS digital circuits. To produce long-range ordered two-dimensional arrays inherent to such technologies, the hybrid combination of “bottom-up” self-assembly and “top-down” guiding patterned templates has been successfully introduced. This has led to new technological breakthroughs wherein the self-assembly of block copolymers (and in particular poly(styrene)-b-poly(methyl methacrylate)) are the cornerstone of the “bottom-up” nanofabrication processes through their segregation behavior into periodic mesostructures.
In this project we target to design novel block copolymers in order to build hierarchical block copolymer structures with multiple periodicities. The resulting 3D structures will then be hybridized with functional objects. The candidate will more particularly synthesize the block copolymer materials and study the self-assembly of block copolymers in the thin film configuration in order to establish the design rules of such 3D block copolymer structures.

Activities

- Synthesis of block copolymers
- Characterization of the synthesized materials
- Study of phase behavior
- Directed self-assembly in thin films

Skills

- Chemistry of polymers
- Macromolecular characterization, Scattering methods, Electron Microscopy
- Team capability and strong personal drive

Work Context

The Laboratory of Chemistry of Organic Polymers (LCPO) is a joint research unit affiliated to the CNRS, the University of Bordeaux and the Institut Polytechnique de Bordeaux (http://www.lcpo.fr). The LCPO is organized into 4 research teams with a total strength of nearly 150 people, including about 50 permanent staff.

With over 30 years of expertise in polymer chemistry, researches at LCPO aim at:
- developing innovative methodologies for precision synthesis of polymers, using in particular biomimetic and/or green chemistry pathways
- designing functional polymer materials by macromolecular engineering and self-assembly, in the fields of renewable materials, health and energy
- establishing strong links with the socio-economy world.

The work of the recruited agent will be carried out in team 4 of the LCPO.

Team 4 entitled “Polymer Electronic Materials & Devices for energy and information technology” is headed by Professor Georges Hadziioannou. The team explores the synthesis of functional (co-)polymers, their formulation and their integration in organic electronic devices. This team is particularly specialized and interested in :
- semiconducting organic (co)polymers for energy (thermoelectricity, photovoltaics) and lighting
- block copolymers for advanced lithographic, energy and information storage applications
- organic conductive and electrophoretic inks for transparent electrodes and color reflective displays respectively.
- ferroelectric materials for information storage, sensors, actuators, electrocaloric systems and energy applications.
