Abstract

The development of commercially viable “green products” based on natural resources for both matrices and reinforcements for a wide range of applications is on the rise. This effort includes new pathways to produce natural polymers with better mechanical properties and thermal stability using nanotechnology and use of natural polymers to make biodegradable plastics and their composites with lignocellulosic fibers. This paper presents an overview of the developments made in the area of biodegradable composites, in terms of market, processing methods, matrix–reinforcement systems, morphology, properties and product development. Some critical issues and suggestions for future work are discussed, underscoring the roles of materials scientists and textile engineers for the future of these new “green” materials through value addition to enhance their use.

Abstract

Green coconut fiber, a lignocellulosic material native from Brazilian northeast coast, was chemically treated by three methods: NaOCl, NaOCl/NaOH or H₂O₂. The effect of these treatments on the structure, composition and properties of fibers was studied using SEM, FTIR, XPS, TGA and other analyses. SEM showed that treatment with H₂O₂ is the most efficient in terms of waxy and fatty acid residues removal but it does not modify the surface chemical composition, that it can be seen by FTIR and wettability results. The chemical composition and FTIR analyses revealed a reduction of the hemicelluloses content in the fibers treated with NaOCl/NaOH and, consequently, this fiber showed a greater exposure of cellulose and a reduction in thermal stability. The fiber surface treated with NaOCl is morphologically similar to the natural fiber surface, have the element Cl on your surface and it is a little more hydrophilic than the natural fiber.

Abstract

Selected physico-chemical and chemical characteristics of 13 coconut coir dust (mesocarp pithy tissue plus short-length fibres) samples from Asia, America and Africa were evaluated as peat alternatives. All properties studied differed significantly between and within sources, and from the control Sphagnum peat. pH of coir dust was slightly acidic, whereas salinity varied dramatically between 39 and 597 mS m⁻¹in the saturated media extract. The cation exchange capacity and carbon/nitrogen (C/N) ratio ranged from 31.7 to 95.4   and from 75 to 186, respectively. Most carbon was found as lignin and cellulose. The concentrations of available nitrogen, calcium, magnesium and micro-elements were low, while those of phosphorus and potassium were remarkably high (0.28–2.81 mol m⁻³ and 2.97–52.66 mol m⁻³ for P and K, respectively). Saline ion concentrations, especially chloride and sodium, were also high.
