Description
Summary:Concerns on environmental issues are motivating the development of biodegradable materials and the use of sustainable processes. Among the most abundant biodegradable materials are lignocellulosic fibers, which could have widespread use as reinforcing fibers in polymer composites. On the other hand, cold plasma treatment is a sustainable process which is lately gaining great interest for the surface treatment of lignocellulosic fibers aimed at improving the mechanical properties of polymers. Despite such great interest, polymers reinforced with plasma-treated lignocellulosic fibers (PRPLF) remain unknown for most industries manufacturing polymer composites. This review summarizes published studies on PRPLF and discusses the effect of plasma treatment of lignocellulosic fibers on the mechanical properties of PRPLF. The interfacial shear strength, tensile and flexural strength, and stiffness of a variety of PRPLF composites are presented and compared in data tables. Additionally, the tensile strength and stiffness of some plasma-treated lignocellulosic fibers are compared in a data table. Finally, the use of micromechanical models is encouraged to estimate the micromechanical properties of PRPLF. Graphical abstract
