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 ...

Mechanical properties of composites with graphene oxide functionalization of either epoxy matrix or curaua fiber reinforcement

Journal of Materials Research and Technology, 2020
In the present work, two types of composites were produced, both reinforced with 30 vol% of curaua fibers (CF). In the first type, only the fiber was functionalized with graphene oxide (GO), producing the GOCF/EM composite.
