| dc.description | The ‘best’ silk fibres (natural polyamide), present a very high breaking resistance but also a huge variability (typically 200-1000 MPa). Films made of Bombyx mori fibroin showed good biocompatibility suitable for biomedical applications, as silk was used as suture material for centuries. Solubilisation process degrades macromolecules and mechanical properties of regenerated silk, ultimate strain and stress, are drastically lower (a few %) than those measured for raw fibres. The goal of this work is to improve tensile mechanical properties of regenerated silk films by silk fibres reinforcement, degummed or not. Degummed fibres (i.e. without sericin coating) are dissolved and dialysed in order to obtain a liquid/gel more or less viscous followed by evaporation to obtain silk matrix. Structure and orientation modifications of fibroin macromolecules are monitored by Raman spectroscopy. The incorporation of a few fibre % vol improved the breaking resistance and dissipation. The mechanical behaviour of regenerated silk-base materials appeared as being dependent from chemical treatment and many parameters have to be optimized. | en_US |
