Group description

The AMP group is devoted to understanding structure, morphology, functionality and properties of semi-crystalline multiphasic polymers. It studies a wide diversity of multiphasic materials by designing and compounding blends, nano-structured blends, nanocomposites and bionanocomposites or by collaborating with different polymer synthesis group that can prepare novel materials capable of providing insights on self-assembly and physical properties.

The techniques commonly employed by the group for its research include Differential Scanning Calorimetry (DSC), Thermogravimetry (TGA), cone microcalorimetry, polarized optical microscopy (PLOM) and atomic force microscopy (AFM). Aditionally, electron microscopy (SEM and TEM) and x-ray diffraction are employed for morphological and structure characterization in collaboration with other groups or using UPV/EHU central facilities. Diverse multiphasic materials are prepared by different techniques of melt compounding and mechanical properties (DMTA, tensile and impact) are also determined as well as rheological behavior in collaboration with the Processing and Rheology groups at Polymat.

Research Lines

ADVANCED MATERIALS AND PROCESSES

Multiphasic biodegradable polyesters

  • In this research line it is included the investigation of several isodimorfic random copolyesters, bionanocomposites and double crystalline diblock and random copolymers. In particular the group has focussed its attention to random copolyesters that can exhibit double crystalline behaviour. Tailoring their supramolecular morphology by means of changing their crystallization conditions and compositions can lead to different biodegradation rates.

Crystalline memory, self-nucleation and thermal fractionation by SSA (Successive Self-nucleation and Annealing).

  • One important contribution of the group is the development of advanced calorimetry protocols to study semi-crystalline polymeric materials. Amongst those, complex self-nucleation protocols, different ways to study isothermal crystallization kinetics and thermal fractionation techniques, such as SSA is now widely employed by the international research community working with thermal analysis of polymers. Such techniques are now being expanded to cover ultra-fast heating and cooling conditions.

Cross-border Collaboration (if any)

The Advanced multiphasic polymer group has had some previous collaboration with the LCPO (Laboratoire de Chimie des Polymeres Organiques) from Bordeaux University, and the results were published in: Bossion, A.; Aguirresarobe, R. H.; Irusta, L.; Taton, D.; Cramail, H.; Grau, E.;  Mecerreyes, D.;  Su, C.;  Liu, G.;  Müller, A. J.; Sardon, H.  Macromolecules,  2018, 51, 5556−5566 (July). “Unexpected Synthesis of Segmented Poly(hydroxyurea−urethane)s from Dicyclic Carbonates and Diamines by Organocatalysis”. DOI: 10.1021/acs.macromol.8b00731. The co-authors from LCPO are: Taton, D.; Cramail, H.; Grau, E

In particular Prof. Daniel Taton has visited UPV/EHU and we have discussed possible future collaborations.
