Halloysite nanotubes as sustainable nanofiller for paper consolidation and protection

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