Document Title:	Nanotechnologies -- Crystallinity of cellulose nanomaterials by powder X-ray diffraction (Ruland-Rietveld analysis)
url:	https://webstore.ansi.org/standards/iso/isots233612024
Scope:	This document specifies the determination of the bulk crystallinity (crystalline contribution relative to the total crystalline and amorphous contributions in the material) of cellulose nanomaterials using powder X-ray diffraction followed by deconvolution of the diffraction patterns based on Ruland-Rietveld analysis. It is applicable to all types of cellulose nanomaterial
Keywords:	cellulose nanomaterial, measurement technique
Type of Document:
Issues Areas:	Measurement and Characterizations
Primary Category:
Additional Categories
Goal or Need:	Crystallinity is an important property for CNM characterization. Multiple experimental methods are in current use, including powder X-ray diffraction (XRD), differential scanning calorimetry and sold-state nuclear magnetic resonance and there is an urgent need for standardization.
