N2 - Crystallinity (CI) and crystallite size (Dhkl) of cellulose nanoparticles obtained from commercial cellulose (cotton) have been evaluated after a ball milling by the deconvolution method. Ball milling was used to achieve cellulose nanoparticles based on the values of crystallite size previously reported. Variations in the CI were found in a range from 88% to 45%. Crystallite sizes were evaluated in an initial value from 4.99 nm that decrease until 1.41 nm by ball milling. A clear dependency of CI and Dhkl was found since ball milling decrease the CI until a re-Agglomeration of the samples is found. Results for Dhkl reveals that cotton cellulose is a soft material easy to grind into nanoparticles in a heterogenous way as authors reported before. Cross-contamination due to higher quantities of silicon oxide was found after two-hour milling. This study presents an insight into the behavior of cellulose nanoparticles using ball milling and the selection of a time in which non-cross contamination or re-Agglomerations have been found.
