RbstractThe need to develop and commercialize materials containing vegetal fibers has grown in order to reduce environmental impact and reach sustainability. Large amounts of lignocellulosic materials are generated around the world from several human activities. The lignocellulosic materials are composed of cellulose, hemicellulose, lignin, extractives and ashes. Recently these constituents have been used in different applications; in particular, cellulose has been the subject of numerous works on the development of composite materials reinforced with natural fibers. Many studies have led to composite materials reinforced with fibers to improve the mechanical, physical, and thermal properties. Furthermore, lignocellulosic materials have been treated to apply in innovative solutions for efficient and sustainable systems. This paper aims to review the lignocellulosic fibers characteristics, as well as to present their applications as reinforcement in composites of different polymeric matrices.

“…In recent decade, enormous efforts have been experimentally devoted for development of rapid, simple, and sensitive methods for sulphate adsorption. [4][5][6] For example, Mulinari et al 4 have investigated adsorption of sulphate ions by modification of sugarcane bagasse cellulose and showed a good adsorption capacity. Removal of sulphate ions from aqueous solution using modified rice straw was studied by Cao et al.…”

The adsorption behavior of the sulphate (SO4 2− ) on the external surface of (5,0), (8,0), and (10,0) zigzag AlNNTs was studied by using density functional calculations. Adsorption energies in the nanotubes are about −8.59, −8.04, −8.60 eV with a charge transfer of 0.59, 0.48, 0.56|e| from the sulphate ion to the nanotubes, respectively. The adsorption energies indicated that sulphate ion can be absorbed strongly on the nanotubes. Therefore, these nanotubes can be used for adsorption of sulphate ion from the environmental systems. It was found that diameter of the AlNNTs has slight role in the adsorption of sulphate ion. The electronic properties of the nanotubes showed notable changes upon the adsorption process.

“…The material was precipitated with an ammonium solution (1:3) at pH 10.0. The mixture was stirred, filtered, exhaustively washed with distilled water for the complete removal of chloride ions (negative silver nitrate test), and dried at 50 °C for 24 h. The resulting material was designated palm fibre/ZrO 2 .nH 2 O (Mulinari and Da Silva 2008).…”

“…Recently, much attention has been directed to the development of nanocomposites based on organic-inorganic hybrid materials, such as SiO 2 (Pinto et al 2008), CaCO 3 (Vilela et al 2010), NbOPO 4 ·nH 2 O (Pereira et al 2010,), Nb 2 O 5 (Maschio et al 2012), MgO (Maliyekkal et al 2010), silica (Xie et al 2009), TiO 2 (Daoud et al 2005), Al 2 O 3 (Alfaya and Gushikem 1999), ZrO 2 (Mulinari and Da Silva 2008), Cel/Sb 2 O 3 (Toledo et al 2000), and other applications such as membranes (Biron et al 2012), because these materials normally have improved mechanical, optical, and thermal properties due to the combination of inorganic and organic components.…”

Chemical modification of natural fibres has been carried out using different methods for such purposes as reinforcement in polymer matrices and heavy metals adsorption. In this work, palm fibres were modified by zirconium oxychloride in situ. The palm fibres that had been chemically modified were compared to those in nature using fibres that passed through 20 and 40 mesh screens to evaluate the influence of particle size on modification. Palm fibres were modified with ZrO 2 .nH 2 O nanoparticles through the use of zirconium oxychloride in an acidic medium in the presence of palm fibres using ammonium solution (1:3) as the precipitating agent. Scanning electron microscopy (SEM), X-ray diffraction (XRD), infrared spectrophotometry (FTIR), and atomic emission spectrometry with inductively coupled plasma (ICP-AES) were used to characterize the hybrid materials. Results indicated that the particle size of the palm fibres influenced in the modification, because the fibres with smaller particle size had a greater deposition of inorganic material. The ICP technique revealed an increase of 21% nanoparticles ZrO 2 .nH 2 O deposited on fibres (40 mesh) when compared to fibres (20 mesh). The diameter of nanoparticles ZrO 2 .nH 2 O deposited on fibres was about 50 to 220 nm, as observed by SEM.
