Hybrids materials can be either
- Homogenous systems – monomers and miscible organic or inorganic components
- Heterogenous (also called nano-composites) where at least one of the components’ domains has a dimension ranging from a few Å to several nm.
It is obvious that the properties of those materials are not only the sum of the individual properties but that the interfaces can have a predominant influence.
Two classes of hybrid materials can be defined in relation to their interface nature:
- The organic and/or inorganic components are blended together and only weak bonds (hydrogen, van der Waals or ionic) form the interface
- The organic and/or inorganic components are linked together via strong covalent chemicals bonds
Our activities relate to the study and the understanding of the processes of formation of hybrid nanostructured materials to allow their tailored fabrication (composition, size, morphology, self-assembling, etc) along with a final control over their chemistry and associated properties in devices.
We are more specifically interested in blends of donor/acceptor materials as conjugated polymers/PCBM and the control of their morphology, in block copolymers made of conventional polymer blocks (see research domain: conventional polymers) and semiconducting polymer blocks, block copolymers made of donor and acceptor pi-conjugated blocks (see research domain: π-conjugated molecules and polymers), self-assembling nanostructures, nanofibers, nanoparticles, etc
