Researchers successfully used dielectric barrier discharge plasma to treat wood-based cellulose nanofibril films. The process significantly reduced liquid water absorption to less than 1% as of the publication date on September 8, 2026.
Why it matters
Cellulose nanofibril films are sustainable but traditionally suffer from poor moisture barrier performance. This advancement provides a potential path toward creating viable, eco-friendly alternatives to petroleum-based plastic packaging.
The study measured liquid water absorption at less than 1% following the application of organosilicon fragments. Researchers utilized static-mode deposition and multilayer formation to modify the surface chemistry of the wood-derived films.
The players
North Carolina State University
This institution served as the lead organization for the research project.
Masaryk University
This institution participated as a collaborating partner in the study.
University of Quebec in Rimouski
This university provided collaborative research support for the development of the films.
U.S. Department of Agriculture
This federal agency provided the necessary funding to support the research effort.
The details
The research team applied dielectric barrier discharge plasma coatings to modify the surface of cellulose nanofibril films, which are naturally hydrophilic. By depositing organosilicon fragments, the scientists successfully adjusted the surface chemistry to create a robust moisture barrier.
Timeline
The findings were published in the journal Applied Surface Science on September 8, 2026.
The Big Picture
This discovery represents a shift in material science, moving past the limitations of traditional cellulose films that struggle with environmental exposure. It follows the ongoing trend of replacing petroleum-based plastics with wood-derived materials in the development of sustainable cellulose-based packaging.
This innovation could lead to the production of high-performance, biodegradable packaging that is more resistant to spoilage and environmental damage. Future consumer products may utilize these films to reduce reliance on plastics while maintaining structural integrity during storage.
The takeaway
Advancements in surface modification techniques are essential for making bio-based materials competitive with synthetic alternatives. The ability to control surface chemistry via plasma technology offers a promising path for creating more durable, sustainable packaging solutions.
