Work in progress:
Development of a new series of biodegradable and biobased polyurethane thermosets derived from renewable feedstocks with tunable thermal properties, optical transparency, good mechanical performance (7.3< tensile strength (MPa) <33.4 and 15.6< strain (%) <189), and promising practical applications…

Research is currently underway in our labs to develop a new series of bio-based polyurethane (PU) thermosets with tailored properties!! The solvent-free synthesis process of these cross-linked PU networks involves the use of new sustainable polyols featuring unique macromolecular architectures made 100% from biomass, particularly hemicellulosic sugars. The polymerization was successfully carried out under mild conditions (< 50 °C) and took only 5 min!! Let’s move on together to greener materials in the future!!

Our contribution to the development of the renewable thermoplastic polyester material, poly(lactic acid) PLLA, was recently published in International Journal of Biological Macromolecules (IF: 8.025 / Q1), in collaboration with Prof. Alejandro J. Müller from the University of the Basque Country UPV/EHU, Spain.
The title of the open access article: “Effect of the structural features of biobased linear polyester plasticizers on the crystallization of polylactides”
In this work, three new 100% biobased polyester plasticizers derived from adipic acid (AdA) were successfully employed, for the first time, to accelerate the crystallization rate and enhance the mechanical properties of polylactide (PLLA); an important step to improve its performance and expand its range of applications.
For more details, visit the link below: https://doi.org/10.1016/j.ijbiomac.2022.06.056
The addition of AdA-based plasticizers to PLLA:
> significantly increases the elongation at break up to 8 times compared to neat PLLA.
> increases the nucleation rate from the glassy state by around 50-110 %.
> causes a remarkable increase in the overall crystallization rate from the glassy state which was 2-3 times faster for the plasticized PLLAs than neat PLLA.
> decreases Tg by up to 11 ºC
Such findings make these aliphatic polyester plasticizers derived from fully renewable resources very promising for improving the properties and applications of PLA.

This week I presented my work entitled “Designed from Recycled PET packaging waste” at Nordic Polymer Days 2022 Conference in Gothenburg, Sweden. It has been a great opportunity to discuss with many inspiring scientists.
In this work, an efficient and fast end-of-life management of non-degradable poly(ethylene terephthalate) thermoplastic waste by chemical recycling was designed. The approach involves transforming PET waste, exemplified by a post-consumer PET bottle, by microwave-assisted solvent-free aminolysis into new value-added terephthalate diamines featuring high melting points. These monomers were then used to synthesize new aromatic-aliphatic high Tg polyimines.
Transforming post-use terephthalate packaging into new high-performance monomers and polymers with outstanding performance, rather than sending them to landfill or incineration, is a much-needed step to prevent generation of packaging waste and to reduce the fatal effects of plastic pollution on our planet.

I am delighted to attend the 5th European Conference on Green and Sustainable Chemistry – 5th EuGSC (26-29 September 2021), where I presented my latest work entitled: “Tuning thermal properties and biodegradability of Isosorbide-based polyester by compositional control through copolymerization with 2,5-furandicarboxylic acid“
These innovative copolyesters, distinguished by improved thermal performance, noticeable susceptibility to enzymatic degradation, and sustainability are highly desired.

COST network wants to introduce innovative and sustainable furan-based plastics on the market
Did you know that many alternatives exist to move-away from unrenewable fossil-resources-based plastic as we use it today?
Different biomass-derived polymers are possible and could be introduced on the market, but challenges remain as research and initiatives are scattered.
COST Action FUR4sustain brings together experts from multidisciplinary backgrounds and looks at innovative solution such as furans for green alternatives.

07 August 2020 In my latest study published in Polymer Degradation and Stability “IF=5.030” (click here), a truly efficient, practical, and more environmentally friendly solvent-free synthetic route was successfully applied herein to prepare three new fully biobased diol monomers derived from vanillic acid. To ascertain their stability toward the conditions of melt polycondensation, these diols were subjected to melt polycondensation with diacyl chlorides having different length alkane bridges and also with dimethyl furan-2,5-furan dicarboxylate.
The overall conclusion is that such work is a concrete contribution towards the valorization of vanillic acid. It can be used as a support and helpful reference to highlight the feasibility of a more environmentally benign solvent-free pathway for sustainable building blocks design.
This innovative synthesis route that could be readily applied at industrial scale makes the development of fully biomass-derived plastics easier and faster, which is the real willingness of both the scientific and industrial communities.
15-17 July 2020 It is delighted to give an oral presentation at virtual Milan Polymer Days conference (MIPOL2020) about our recent work entitled: “Solvent-free synthesis of new fully biobased diol monomers through industrially viable approach: Toward new insights into the valorization of vanillic acid-based polyesters” (Click here)
16 March 2020 For first time, the synthesis of a novel furanoate polyester-urethane with vitrimer-like behavior was reported in our lastest publication published in Biomacromolecules “IF=6.988” (Click here)
04 February 2020 In our recent study published in Thermochimica Acta (click here), the effect of three different stabilizers on the physicochemical properties of the poly(ethylene 2,5-furan dicarboxylate) (PEF) biobased polyester have been studied for the first time.
25 September 2019 My recent paper published in Polymer Degradation and Stability “IF=5.030” (click here), describing an effective solution for overcoming the low glass transition temperature (Tg) of poly(hexamethylene 2,5-furan dicarboxylate) (PHF), is proposed that uses isosorbide as a bicyclic rigid diol comonomer. Such kind of copolymers developed herein, which combines both the sustainability and improved thermal performance, is highly desired…
12 February 2019 Our recent study, published in ACS Sustainable Chemistry & Engineering “IF=8.198”, spotlighted a successful synthesis of a novel series of biobased poly(decamethylene-co-isosorbide 2,5-furandicarboxylate)s copolyesters from dimethylfuran-2,5-dicarboxylate, isosorbide, and 1,10-decanediol by melt polycondensation. These prepared materials revealed high sensistivity to the biodegradation process in soil, in addition to superior mechanical properties. Taking advantage of their features, PDIsFs have the potential to serve as promising and innovative biobased polymers for practical applications such as ecofriendly and sustainable plastic packaging.
10 February 2018 In this paper published in Polymer Degradation and Stability “IF=5.030”, we successfully synthesized by melt polycondensation a biobased Furanoate series of random poly(1,4-cyclohexanedimethanol-co-isosorbide 2,5-furandicarboxylate)s (PCIsFs) copolyesters. The prepared copolyesters showed good thermal stability. The efficiency of isosorbide insertion into polymer backbone was proved to be efficient route to enhance the thermal properties, for example significant increase in Tg, as well as to control the crystallinity and crystallization rate for PCIsFs copolyesters. It is noteworthy that, thanks to isosorbide, a correlation between PCIsFs chemical structure and their crystal structure and thermal characteristics were found…
