Poly(3-hydroxyalkanoate)s (PHAs), have been suggested as green substitutes to replace petroleum-based commodity
polymer because of their biodegradability, biocompatibility and versatility. Although PHAs are very promising material
in the field of eco-friendly plastics, their intrinsic brittleness and narrow processing temperature window limit their range of
application. As a consequence, many attempts have been made to develop PHA with better mechanical and thermal properties.
In recent years, much attention has been focused on the development of polymeric materials from vegetable oils, a sustainable
resource. Their competitive cost, worldwide availability and built-in functionality (ester functions and in saturations) make
them attractive to reinforce various types of polymers. In this study, we reported a unique approach to toughen PHAs by
increasing their elongation at break and enhancing their thermal stability using sunflower oil (SO). The strategy consisted of
synthesis of a bio-based semi-interpenetrating (semi-IPNs) network by crosslinking sunflower oil and triméthylolpropane
tris(3-mercaptopropionate), a trithiol using “click” thiol-ene reactions into linear PHA polymer matrix. This functionalization
process that is characterized by high yields, high reaction rate and short reaction time was initiated photochemically by
ultraviolet light in the presence of a photoinitiator 2,2-diméthoxy-2-phénylacétophénone (DMPA). The resulting semi-
IPNs PHA/SO exhibited excellent flexibility and showed relatively good thermal stability. Mechanical analysis results have
shown that semi-IPNs with 30 wt% of cross-linked sunflower oil displayed excellent properties with an increase of the elastic
modulus (170%) as compared to pristine PHA (7%). Moreover, it has been demonstrated that the thermal stability of the
semi-IPNs increased by incorporation sunflower oil into PHA matrix. Moreover, a single glass transition temperature for the
semi-IPN containing sunflower oil up to 30% was observed with dynamic mechanical analysis (DMA), which suggested good
compatibility between sunflower oil and PHA in the network.
Biography
Carine Mangeon is pursuing her PhD at the East Paris Institute of Chemistry and Materials Science, Thiais, France, since September 2014. Her scientist
research deals with the development of new bio-based polymeric materials. The main goal of her study consists in developing and improving the properties of
polyhydroxyalkanotaes (PHA) produced from bacterial strains in order to enhance their thermal and mechanical properties. She has published two patents and
one publication in this research field.
