Halloysite Nanotubes for Cleaning, Consolidation and Protection

Abstract Herein, we report our recent research concerning the development of halloysite based protocols for cleaning, consolidation and protection purposes. Surface modification of halloysite cavity by anionic surfactants was explored to fabricate inorganic micelles able to solubilize hydrophobic contaminants. Hybrid dispersions based on halloysite and ecocompatible polymers were tested as consolidants for paper and waterlogged archaeological woods. Encapsulation of deacidifying and flame retardant agents within the halloysite lumen was conducted with aim to obtain nanofiller with a long‐term protection ability. The results prove the suitability and versatility of halloysite nanotubes, which are perspective inorganic nanoparticles within materials science, remedation and conservation of cultural heritage fields. Halloysite nanotubes are ecocompatible nanoparticles that can be successfully employed as adsorbents, fillers for consolidation of lignocellulosic materials, and nanocontainers for chemically active molecules with applications in different fields of technology and material sciences.
