We investigated the ﬁlling process of cellulose- based paper with natural clay nanotubes and their mixtures with hydroxypropyl cellulose (HPC) that is commonly used as glue and consolidant for degraded paper. A compre- hensive 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 co-presence of HPC and nanoparticles generated a more uniform nano- tubes distribution in the paper ﬁbrous structure and a sig- niﬁcant enhancement of both the mechanical properties and the surface hydrophobicity with respect to the HPC treat- ment. This work proposes the use of halloysite/HPC mix- ture 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.
