High-Barrier, Photothermal Conversion, and Antibacterial Composite Enabled by Kraft Lignin-Coated Cellulose Paper for Plastic Replacement
Bibliographic record
Abstract
Paper-based materials demonstrate considerable potential as a substitute for plastic packaging. However, their limited barrier properties, singular functionality, and intricate preparation methods pose challenges to further advancement. Specifically, the inadequate barrier adversely impacts the preservation of paper-based packaging materials under conditions characterized by high humidity and prolonged exposure to sunlight. Herein, a refined preparation strategy is proposed for the direct and enhanced production of a biodegradable multifunctional barrier packaging paper. Lignin is deposited onto the surface of cellulose paper (CP) via vacuum filtration followed by conversion into lignin/cellulose paper (LCP) through a simple hot-pressing process. The resulting LCP exhibits outstanding barrier properties (Kit grade of 12, water vapor permeability of 197 g/(m 2 ·24 h) at 37 °C and 90% RH) and wet strength (50.79 MPa). Moreover, the prepared LCP also exhibits rapid and stable photothermal conversion capability, along with remarkable photothermal antibacterial activity (photothermal antibacterial rate >99.9%). The overall prepared LCP exhibits numerous advantages, encompassing an intact biobased composition, degradability, environmental protection, and exceptional barrier properties. Therefore, it presents an optimal alternative to conventional plastic packaging materials, offering an efficient solution for product storage across diverse environments while also providing a sustainable and cost-effective approach to the production of barrier packaging materials.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
