Halloysite nanotubes/Keratin composites for wool treatment
Source abstract
Abstract
The optimization of a consolidation and protection coating for wool-based artefacts is a challenging issue for conservator of cultural heritage. In this study, an aqueous dispersion containing Keratin (K) and Halloysite nanotubes (Hal) was investigated in a coating protocol for wool thread. Colorimetric analysis and optical microscopy revealed the surface characteristic of wool. Scanning electron microscope showed the halloysite nanotubes distribution in the wool fibers. The protection efficacy after UV-irradiation was evaluated and the mechanical analysis gave us direct information on consolidation and protection effect of Hal/K mixtures in treated wool thread samples. The formulation with the optimal performances was used on conservation protocol for a historical yarn. The obtained results indicate that the proposed protocol is promising to generate a reinforcing coating layer onto wool-based yarn also providing protection from deterioration due to UV exposure with a minimal impact on the sample aesthetic aspects.
