Smart nanocomposites based on thermally reversible networks
Francesco Picchioni
University of Groningen, The Netherlands
T
he use of nano-fillers in thermally reversible networks
constitute and easy as well as extremely attractive route
to smart nanocomposites. In particular, the Diels Alder
reaction between furan and maleimide derivatives has been
extensively reported for the preparation of nanocomposite
materials that exhibits heat or electricity induced self-
healing, shape memory and possibility for cradle-to-cradle
recycling. The covalent nature of the Diels-Alder adducts
ensures relatively high glass transition temperatures, while
its reversible character provides the necessary dynamic
character that ensures the possibility for self-healing and
shape memory effects. In the present work, we will start
by briefly illustrating the wide variety of substrates suitable
for modification with Diels-Alder active groups and their
self-healing behavior. Against this backdrop, the special
case of nanocomposites will be illustrated as paradigmatic
example for the possible use of this interaction also between
a polymeric matrix and a filler. In particular, the use of
carbon nanotubes as filler paves the way towards shape
memory materials as well as electricity-induced self-healing.
Speaker Biography
Francesco Picchioni obtained his PhD (2000) in Polymer Chemistry at the
University of Pisa (Italy) on a project dealing with thermoplastic rubbers.
After 3 years postdoc at the Technical University of Eindhoven (on a project
about “solid state modification of polypropylene”), he joined in 2003 the
University of Groningen first as assistant professor and then associate
(2007). Since 2013. He is full professor in Chemical Product Engineering. He
is (co)author of about 90 papers in peer-reviewed journals and 4 patents.
