Effect of chemical agents on morphology, tensile properties and water diffusion behaviour of hibiscus sabdariffa fibers. Chemical and Process Engineering Research 42, 76 - 83p-2224-7467e-2225-0913https://repository.futo.edu.ng/handle/20.500.14562/1562The article contains tables and figuresEffective utilization of Hibiscus sabdariffa fibers in composites applications as a reinforcing fibers in polymer matrix have been a major concern due to its poor mechanical and hydrophilic properties. It will be of benefits to environmental and technological advancement, if its properties are properly handled. In this study, the morphological, tensile and water absorption characteristics of H. sabdariffa fibers was aimed to be investigated. H. sabdariffa fibers was modified using sodium hydroxides, sodium lauryl sulphate and ethylene diamine tetraacetic acid. The morphology using scanning electron microscopy, tensile properties (strength, modulus, elongation and energy at break), water absorption and water diffusion behaviours were studied. Chemical modifications improved fiber surface and roughness, tensile strength and modulus, elongation and energy at break with reduced water absorption of H. sabdariffa fibers. The water diffusion behaviour is less - Fickian controlled by water penetration rate. Hence improved the hydrophobic nature of H. sabdariffa fibers.enAttribution-NonCommercial-ShareAlike 4.0 InternationalHibiscus sabdariffa fibers tensile propertiesmorphologywater diffusion behaviour Hibiscus sabdariffa fiberstensile propertieswater diffusion behaviourDepartment of Biomedical TechnologyArticle
