Abstract
We investigated the filling process of cellulosebased paper with natural clay nanotubes and their mixtures with hydroxypropyl cellulose HPC that is commonly used as glue and consolidant for degraded paper A comprehensive characterization of the materials was carried out through morphology wettability thermal degradation and tensile properties The treatment with halloysite nanotubes generated a decrease of the paper mechanical performance and did not alter the thermal properties The copresence of HPC and nanoparticles generated a more uniform nanotubes distribution in the paper fibrous structure and a significant enhancement of both the mechanical properties and the surface hydrophobicity with respect to the HPC treatment This work proposes the use of halloysite/HPC mixture in a new protocol for paper consolidation and represents a starting point to develop with a biocompatible approach smart composite material in which the nanotube cavity is filled with active species for paper protection or active response to external stimuli
