Learn about current activities in measuring size distributions of Cellulose Nanomaterials

Register today for TAPPI's free webinar Current activities in measuring size distributions of Cellulose Nanomaterials held on Wednesday, August 19th 8AM-10AM EST. This webinar will present current activities in measuring particle size and size distributions of cellulose nanocrystals (CNC) along with cellulose nanofibrils (CNF), highlighting the successes, the failures, the challenges, and future efforts that are needed for the development of standardized methods.

Keep in mind that 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.

 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.

Webinar attendance is free and open to everyone, but registration is required. Reserve your space today!

Robert Moon, Ph.D.


Since 2007 he has worked in the area of cellulose nanomaterials (CNMs), developing processing-structure-property relationships as they apply to various aspects of CNMs research, including CNM characterization and standards development. In the area of CNMs, he has 48 SCI ranked journal publications, 2 critical review, 2 patents, and a co-editor of 1 book. Dr. Moon’s current work in CNM characterization is in the development of semi-automatic image analysis tools for CNMs particle morphology measurement. Among his outreach activities in standards development he is the Convenor for the technical group ISO/TC 6/TG 1 – Cellulose nanomaterials, and is a member of ISO/TC 229-Nanotechnology.
