报告摘要：
Nanocellulosehas been a well-established area of research for several decades; however,progress in its production, application, and utilization has been hindered bythe lack of measurement standards. Measurement techniques often involvesignificant trade-offs; for example, optical fiber analysers offer quickresults but fail to detect most fibers in a nanocellulose sample. On the otherhand, scanning electron microscopy (SEM) is slower due to sample preparationand image analysis requirements but is generally capable of imaging mostfibrillar elements in a sample. This talk will report on the work of an ISOtask group within the pulp and paper committee, TC6, working on developingnanocellulose measurement standards within ISO. The first part of the talk willfocus on the group’s work and the process of identifying priorities forstandard method development, with a particular focus on size measurementtechniques. The second part of the talk will be focus on cellulose nanofibrilsize measurements using SEM. Finally, some of the recent work oncharacterisation within my own research group will be introduced. These includea new method combining mercury intrusion porosimetry (MIP) with X-raymicro-computed tomography (μCT) for CNF film structure characterization andcellulose nanofibril aspect ratio measurement using rheology.
报告人简介：
Professor Warren Batchelor is the DeputyHead of Department and Director of Education in the Department of Chemical and Biological Engineering, Monash University, Australian. He is the chair of theStandards Australia PK-019 committee, which develops standards for the pulp andpaper industry and is the Australian representative on the internationalcommittee, TC6. His major research interests are in sustainable materials, witha particular interest in materials from cellulose nanofibers (CNFs), withcontributions including: Recyclability of CNF films and of paper-polymerlaminates; Life-cycle analysis of materials and processes; CNF characterisationmethods including developing standards for CNFs; Paper mill biorefinery and CNFproduction; Methods for the rapid preparation of CNF sheets by spray coatingand vacuum filtration; Development of renewable, recyclable, CNF barrier layersto displace petroleum-derived polymers in packaging; Nanoparticle-cellulosenanofiber composites for barrier applications, ultrafiltration membranes,antimicrobial functional layers and photocatalytic degradation of organiccontaminants.
