We presented the effect of the addition of differently size-structured (20-50 nm) FR nanoparticles of aluminium hydroxide (ATH, Al(OH)3), on thermal (TGA/DSC), mechanical (tensile strength), and optical (Uv-Vis spectroscopy) properties of paper prepared from microfibrilated cellulose (MFC) using solvent casting method. The effect of ATH dispersibility (SEM) and loading quantity (10-50 wt% of ATH, according to dry mass of MFC) was studied. The films chemical structuring and hydrophobic/wetting properties were addressed by FTIR spectroscopy and contact angle measurements. The ATH-loaded MFC films shows an improved thermal stability, where the most effective results were achieved by using 20-30 nm sized ATH nanoparticles dispersed in propanol. The residue content of this film increased up to 40% at 900°C, for 50 w/w% of ATH loading, compared to the pure MFC film (residue of 25.7%), without influencing on their mechanical properties, while reducing the film wettability (contact angle has risen from 43° to 68°), indicating the potential of their use in the manufacture of recyclable and heat-insulating packaging.
