Adhesion and interfacial healing between supramolecular hybrid networks and glass substrates

Véronique Michaud, Federica Sordo

Adhesion towards glass and interfacial healing of partially supramolecular hybrid polymer networks featuring a range of H-bdnds content were investigated through two dedicated adhesion test methods. In a first series of tests, adhesion strength was measure ...

Self-Healing Fiber-Reinforced Composites with Tailored Supramolecular Matrices

Federica Sordo

Fiber Reinforced Composites (FRCs), due to their intrinsic heterogeneity, are generally affected by complex multi-scale failure mechanisms leading to the formation of matrix cracks that are difficult to detect and repair. FRCs with the ability to heal and ...

Processing and damage recovery of intrinsic self-healing glass fiber reinforced composites

Véronique Michaud, Federica Sordo

Glass fiber reinforced composites with a self-healing, supramolecular hybrid network matrix were produced using a modified vacuum assisted resin infusion moulding process adapted to high temperature processing. The quality and fiber volume fraction (50%) o ...

Design of Self-Healing Supramolecular Rubbers with a Tunable Number of Chemical Cross-Links

Véronique Michaud, Federica Sordo

Supramolecular rubbers incorporating a large number of physical cross-links through cooperative hydrogen bonds display high self-healing properties but limited solvent and creep resistance due to the lack of chemical cross-links. Increasing both chemical c ...

One-pot photoinduced synthesis of conductive polythiophene-epoxy network films

Marco Sangermano, Federica Sordo

In this paper, we describe a novel methodology for fabricating conductive epoxy-polythiophene network films by simultaneous photoinduced step-growth and cationic ring opening polymerization processes. For this purpose, formulations containing a bifunctiona ...

UV-Cured Epoxy-Zno Composites: Preparation and Characterization

Marco Sangermano, Federica Sordo

Epoxy-ZnO composites are prepared via UV-induced cationic polymerization. Complete unsoluble materials are achieved after 10min of irradiation. Thermal analyses shows an increase of T-g in the presence of the ZnO attributable to a strong hindrance effect o ...
