Amidation and ionic complexation were evaluated as surface modification treatments for TEMPO-oxidized nanocelluloses (TONc), using octadecylamine (ODA) as the modifying compound. Effects of the two treatments on TONc with respect to degree of ODA substitution, surface hydrophobicity, crystalline characteristics, and thermal decomposition properties were investigated, respectively, with elemental analysis,...
Utilization of TEMPO-oxidized celluloses in bio-based nanocomposites is reported for the first time. TEMPO-oxidized wood pulps (net carboxylate content 1.1 mmol/g cellulose) were fibrillated to varying degrees using a high intensity ultrasonic processor. The degree of fibrillation was controlled by varying sonication time from 1 to 20 min. The sonication products were then characterized independently...
