A laboratory-scale automated vacuum-assisted device for coating of cellulose nanofibrils onto paper, TAPPI Journal November 2025
ABSTRACT: An automated vacuum-assisted coating system was developed to deposit cellulose nanofibril (CNF) layers onto paper substrates, simulating potential industrial geometries while allowing precise control of web speed (10•20 m/min), vacuum time (up to 30 s), and applicator gap (0.5•0.9 mm). Vacuum assistance makes it possible to obtain coat weights over 5 g/m2 in a single pass and increases solids after coating from less than 10% to over 28%• 30%, reducing drying demand by more than 60%. Coat weights were tuned from 6 to over 11 g/m² by varying suspension solids (0.4•0.6 wt%), line speed, and filtration length (20•40 mm), with strong agreement between experimental data and model predictions. Barrier testing showed Kit test values for double folded samples of 9•12 and Gurley air resistances above 4 × 104 s once coat weights exceeded 7 g/m². Comparable performance was achieved with lower fines content CNF (60%) by increasing coat weight, providing technical flexibility and cost advantages for industrial scale-up.
