Research interests
The design of polymers and
supramolecular materials with specifically targeted properties or function
requires a detailed characterization of their structure at the molecular-, nano- and micro-scales. Understanding the interplay
between the processing history and the final structure is also critical since
perturbations often yield materials with completely different properties. In
this context, our research is at the interface between polymer science and
instrumentation development:
- We develop
and apply powerful new infrared (IR) spectroscopy techniques to enable
unmatched time resolution for the dynamic characterization of materials
and/or to provide more information than standard methods:
- Polarization
modulation infrared structural absorbance spectroscopy (PM-IRSAS)
- Planar array infrared (PA-IR)
spectroscopy
- We use Raman spectroscopy and multiple
complementary characterization techniques (XRD, DSC, SEM, etc.) to study
the structure and properties of nanofibers prepared by electrospinning. We
are particularly interested in
- We try to better understand the
structure and properties of the byssus
of
blue mussels. These fibers possess large toughness and elasticity that
vary with environmental factors in a poorly understood fashion. We also
seek the preparation of new biomaterials based on byssus. This work is
in collaboration with I. Marcotte
(UQAM) and R. Tremblay
(UQAR).
- We also collaborate with O. Lebel
(RMC) on the spectroscopic characterization of molecular
glasses, and on various projects involving the
characterization of ultrathin films.
