Study of Vietnamese Natural Fibers Coated with Graphene Oxide for Sustainable Composite Applications

Facingthenegativeconsequencesofclimatechange,numerousglobaleffortsareunderwaytodevelopbio-basedalternatives intended to replace synthetic fibers used in technical applications. However, reproducing the performance, low density, and high flexibility of synthetic fibers remains a challenge. A promising solution that meets these criteria is the use of natural fibers reinforced with graphene. One of the major scientific challenges regarding natural fibers lies in their variability, which depends on complex factors such as growth conditions—most notably soil and weather. In this study, we aim to analyze the mechanical performance of fibers extracted from pineapple leaves in Vietnam, coated with graphene oxide. The effectiveness of various physical and chemical processes to enhance the mechanical properties of natural fibers was investigated both quantitatively and qualitatively.
