Controlling Temporally and Spatially Homogeneous Temperature Distribution of Paper Substrates by Biogenic Phase Change Hybrid Material Coatings

Advanced Materials Interfaces, Volume 12, Issue 3, February 3, 2025.
Phase change materials (PCMs) can absorb energy during their melting process, whereby heat, for example, is attenuated as it passes through. In this study, a mixture of ethylene glycol distearate (EGDS) and cellulose stearoyl ester (CSE) was used as a PCM in paper without the need for encapsulation.

All-cellulose composites from unbleached hardwood kraft pulp reinforced with nanofibrillated cellulose

Cellulose, 2013
In the present work, nanofibrillated cellulose (NFC) from bleached eucalyptus pulp was prepared, characterized and used as reinforcement in an unbleached eucalyptus fiber matrix. First, the NFC was fabricated through TEMPO-mediated oxidation and characterized for the degree of polymerization, water retention value, cationic demand and carboxyl content.

Design of Carboxylic Acid‐Functionalized Poly(Butylene Adipate‐co‐Terephthalate) for Recyclable and Biodegradable Zero‐Waste Paper Packaging

Advanced Sustainable Systems, Volume 9, Issue 1, January 20, 2025.
This study reports a novel method for producing a carboxylic acid‐functionalized poly(butylene adipate‐co‐terephthalate) (CPBAT) copolymer for paper coating. The CPBAT‐coated paper is biodegradable and recyclable and provides excellent water and oil resistance as well as thermal sealing properties.

Quality and yield of pulpwood in drained peatland forests: pulpwood properties of Scots pine in stands of first commercial thinnings

Silva Fennica, 2003
The inherent structural dynamics of drained peatland forests may result in a great variation in various wood and fiber properties. We examined variation in fiber and pulp properties i) among stands, ii) among trees within stands, and iii) within trees

Understanding Polyamidoamine Epichlorohydrin (PAAE) Retention in Paper

BioResources
Polyamidoamine epichlorohydrin (PAAE) is a permanent wet strength resin used in papermaking. When applied to paperboard, some amount of resin is retained in the sheet, and some is lost to the white water.
