BioPRIA Goes to International Paper Physics Conference 2024 (Wuppertal, Germany)

Prof. Warren Batchelor and PhD students Naghmeh Nasiri, Hans Cainglet, and Yasuaki Inoue (left to right in picture) attended the International Paper Physics Conference 2024 at the Bergische Universität Wuppertal in October 2024. Our fellow PhD students delivered the oral presentations listed below:

Congratulations to Naghmeh Nasiri; the recipient of the “Young Researchers Best Presentation Award” for her presentation entitled “Transparent Plasticized Cellulose Nanocrystal Film for High Barrier Performance”. This study presents a sustainable approach to enhancing cellulose nanocrystal (CNC) films for packaging applications by incorporating maltitol, a green polyol plasticizer. The resulting bioplastic films demonstrate significantly improved gas barrier properties, tensile strength, and flexibility, with up to 94% reduction in water vapour permeability. These findings highlight the potential of maltitol-plasticized CNC films as high-performance, eco-friendly alternatives to fossil-based plastics, especially for food packaging applications.

Hans Cainglet presented Enhanced Analysis of Cellulose Nanofibril Film Structure and Barrier Properties. This study demonstrates the power of combining mercury intrusion porosimetry (MIP) and X-ray micro-computed tomography (μCT) to map the nanopore morphology in cellulose nanofibril (CNF) films. Detailed information on the pore morphology and connectivity could be determined with μCT, while MIP provided complementary information about the nanoscale pores. Minimal changes were observed in the pore connectivity, porosity, and pore size distributions at high grammage, which explains the water vapour transmission rate non-zero exponential decay at high grammage observed in previous studies.

Yasuaki Inoue presented Effect of Particle Size on the Properties of Cellulose Nanofiber/Lignin Composite sheets. In this research, we investigated the effect of lignin particle size on the properties of nanocellulose/lignin particle composite sheets. We found that lignin nanoparticles formed a dense layer on the top surface of the sheet, leading to an enhanced water vapour barrier properties and surface hydrophobicity.
