Cellulose Nanowhiskers Extracted from Tempo-Oxidized Curaua Fibers

Journal of Natural Fibers, 2019
The objective of this study was to obtain nanowhiskers from bleached and milled curaua fibers. Nanowhiskers were obtained via a TEMPO system. TEM micrographies proved the fibers were obtained. FTIR analysis showed characteristic peaks of the oxidation products for the samples submitted to the treatment, suggesting that the it was effective for ...

Investigation of the Physicochemical, Thermal, and Mechanical Properties of a Single Fiber Extracted From Imperata Cylindrica Plant

Advances in Materials Science and Engineering, Volume 2025, Issue 1, 2025.
This study investigated the physical, chemical, thermal, and mechanical properties of Imperata cylindrica (IC) fibers extracted using 2 wt%, 4 wt%, and 6 wt% NaOH. Since 6 wt% NaOH yielded complete removal, fibers obtained from this concentration were furthermore treated with 1% concentration of silane before characterization.
