Formation of Carbonyl and Carboxyl Groups on Cellulosic Pulps: Effect on Alkali Resistance

BioResources, 2014
Ozone bleaching generates carbonyl groups on the cellulose polymer when applied to unbleached kraft pulps. This suggests that pulp fully bleached with a totally chlorine-free (TCF) sequence may contain more oxidized groups than standard elemental ...

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.

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.

Kappa Number Prediction of Acacia melanoxylon Unbleached Kraft Pulps using NIR-PLSR Models with a Narrow Interval of Variation

BioResources, 2014
A total of 120 Acacia melanoxylon R. Br. (Australian blackwood) stem discs, belonging to 20 trees from four sites in Portugal, were used in this study. The samples were kraft pulped under standard identical conditions targeted to a Kappa number of 15.

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

In-situ Green Synthesis of Gold Nanoparticles using Unbleached Kraft Pulp

BioResources, 2015
Facile green synthesis of gold nanoparticles (AuNPs) on cellulose fiber was successfully achieved by reducing chloroauric acid (HAuCl4·3H2O) by means of unbleached kraft pulp. A significant color change in pulp fiber indicating the in-situ formation of gold was observed with one-step synthesis in an autoclave.
