Open AccessNatural fiber-reinforced thermoplastic composites can be an alternative to mineral fiber-based composites, especially when economic and environment concerns are included under the material selection criteria. In recent ... -
Impact strength and water uptake behaviors of fully bio-based PA11-SGW composites
(Multidisciplinary Digital Publishing Institute (MDPI), 2018-06-30)
Article
Open AccessComposite materials have attracted the attention of some industrial fields due to their lightness and relatively good mechanical properties. One of these properties is impact strength, essential to ensure the processability ... -
Ionic liquids-assisted bioconversion of lignocellulosic biomass for the development of value-added products
(2021-10-11)
Article
Open AccessLignocellulosic biomass is the most abundant renewable and inexpensive source that can be used to produce biofuels and bioproducts. One of the major limitations of biomass valorisation is its recalcitrance to an efficient ... -
Laccase/TEMPO-mediated graft hydrophobization of jute fibers to enhance the mechanical properties of jute/PLA composites
(2022-01)
Article
Restricted access - publisher's policyIn this work, the hydrophobization of lignocellulosic jute fibers was achieved via the laccase/TEMPO-mediated grafting of octadecylamine (OA) on their surface, with the aim to improve the interfacial compatibility with ... -
