Coating and Surface Modification of Paper
Research Guide
What is Coating and Surface Modification of Paper?
Coating and surface modification of paper involves applying chemical agents, fillers, and nanofibril layers to enhance printability, wettability resistance, barrier properties, and mechanical strength.
This subtopic covers internal sizing (Hubbe, 2007, 172 citations), inkjet coatings (Kettle et al., 2009, 103 citations), and nanocellulose barriers (Mazega et al., 2022, 33 citations). Over 10 key papers from 2007-2022 address interfacial adhesion, hygroexpansion, and pore-scale modeling. Research spans BioResources, Surface and Coatings Technology, and Nanomaterials.
Why It Matters
Coatings improve inkjet print quality by controlling dye absorption on paper surfaces (Lamminmäki et al., 2011, 41 citations; Moutinho et al., 2011, 27 citations). Nanocellulose suspensions enhance moisture and grease barriers for sustainable packaging, reducing plastic lamination (Mazega et al., 2022, 33 citations). Surface modifications minimize hygroexpansion for dimensional stability in high-speed printing (Lindner, 2017, 120 citations; Kettle et al., 2009, 103 citations). PCC-cellulose fillers boost fine paper properties without coatings (Subramanian et al., 2007, 29 citations).
Key Research Challenges
Optimizing Ink Absorption
Balancing rapid ink drying with preventing excessive spreading remains difficult for high-speed inkjet. Coating layers must control dye adsorption without compromising print density (Lamminmäki et al., 2011, 41 citations). Pore structure variations affect hydraulic properties (Aslannejad et al., 2016, 66 citations).
Achieving Multifunctional Barriers
Paper coatings need simultaneous resistance to moisture, air, and grease using biobased materials. Nanocellulose improves barriers but requires uniform dispersion (Mazega et al., 2022, 33 citations). Internal sizing limits wetting but not grease penetration (Hubbe, 2007, 172 citations).
Controlling Hygroexpansion
Fiber swelling under humidity causes dimensional changes, impacting print registration. Factors like sizing and fillers influence expansion rates (Lindner, 2017, 120 citations). Surface chemistry adjustments are needed for stability (Moutinho et al., 2011, 27 citations).
