Upcoming Webinars:

Current activities in measuring size distributions of Cellulose Nanomaterials


Date – 8/19/2020
Time – 8AM – 10AM

Lead Speaker – Linda Johnston

The webinar will present current activities in measuring particle size and size distributions of cellulose nanocrystals (CNC) and cellulose nanofibrils (CNF), highlighting the successes, the failures, the challenges, and future efforts that are needed for the development of standardized methods. The first half of the webinar will focus on the outcomes of a recent interlaboratory comparison (ILC) on CNC particle size measurements. The second half of the webinar will focus on the difficulties of measuring CNF features (e.g., fibril width, branching) that could be used to define/describe CNFs as particles. Recent efforts by the ISO/TC 6/TG 1 – “Cellulosic nanomaterials” working group to provide a framework for the characterization of CNF morphology will be highlighted. In particular, a survey has been developed which will be used to assess standardization needs and priorities for particle size measurements of cellulose micro/nanomaterials including CNF, CMF, MFC, and other fibrillar "nanocellulose" products. The results of the survey will be used to drive CNF/CMF standards development, similar to a 2018 survey by ISO/TC 6/TG 1 on general cellulose nanomaterial characterization requirements that was subsequently used to provide direction of current standards development for both CNCs and CNFs.
