NANOCELLULOSE Setting priorities in CNF particle size measurement:What is needed vs.what is feasible

摘要

Robert J.Moon,Cecilia Land Hensdal,Stephanie Beck,Andreas Fall,Julio Costa,Eiji Kojima,Tiffany Abitbol,Vikram Raghuwanshi,Colleen Walker,and Warren Batchelor Measuring the size of cellulose nanomateri-als can be challenging,especially in the case of branched and entangled cellulose nanofibrils(CNFs).The International Organization for Standardization(ISO),Technical Committee 6,Task Group 1-Cellulosic Nanomaterials,is exploring opportunities to develop standard methods for measurement of CNF particle size and particle size distribution.This work is a summary of the available measuring techniques,responses from a survey on the measurement needs of CNF companies and researchers,and outcomes from an international workshop on cellulose nanofibril measurement and standardization.
