“…Figure 3 shows the morphology of raw flax, flax-g-poly (MMA) prepared in air, under pressure and under the influence of microwave radiations [103]. A number of methods can be used for the generation of active sites on the polymeric backbone and can be described as: physical method [104][105], chemical method [106][107][108][109][110][111][112], physicomechanical method [113], radiation method [114][115][116] and enzymatic grafting [117][118].…”

In recent years, natural fibers reinforced composites have received much attention because of their lightweight, nonabrasive, combustible, nontoxic, low cost and biodegradable properties. Among the various natural fibers; flax, bamboo, sisal, hemp, ramie, jute, and wood fibers are of particular interest. A lot of research work has been performed all over the world on the use of natural fibers as a reinforcing material for the preparation of various types of composites. However, lack of good interfacial adhesion, low melting point, and poor resistance towards moisture make the use of natural fiber reinforced composites less attractive. Pretreatments of the natural fiber can clean the fiber surface, chemically modify the surface, stop the moisture absorption process, and increase the surface roughness. Among the various pretreatment techniques, graft copolymerization and plasma treatment are the best methods for surface modification of natural fibers. Graft copolymers of natural fibers with vinyl monomers provide better adhesion between matrix and fiber. In the present article, the use of pretreated natural fibers in polymer matrix‐based composites has been reviewed. Effect of surface modification of natural fibers on the properties of fibers and fiber reinforced polymer composites has also been discussed. POLYM. ENG.

“…Properties such as renewability, biodegradability, high filling effect, light weight, easy availability, nonabrasiveness, acceptable specific strength properties, ease of separation, enhanced energy recovery, noncorrosive nature, high toughness, low cost, good thermal properties, reduced tool wear, and reduced dermal and respiratory irritation provide attractive ecofriendliness to the resulting natural fibrous materials. [10][11][12] Efforts have been made by various researchers to substitute synthetic fiber with biodegradable natural fiber to effectively use these natural fibers in a number of applications, especially in polymer composite materials. [13][14][15] In fact, several studies reporting natural fiber-reinforced polymer composites have shown that the incorporation of lignocellulosic natural fibers improves the mechanical properties of the polymer matrices.…”

In recent years, interest in using natural fibers in a number of applications especially in biocomposites has grown because they are ecofriendly, lightweight, combustible, nontoxic, low cost and easy to recycle. On the other hand, the lack of good interfacial adhesion and poor resistance to moisture absorption and chemicals make the use of natural fibers less attractive. Chemical treatment of the lignocellulosic fiber can stop the moisture absorption process, clean the fiber surface, chemically modify the surface or increase the surface roughness. Silane treatment of natural fibers is a promising process for improving physical and chemical properties of fibers. The work presented in this article gives insight into the effect of silane treatment on physical and chemical properties of Pinus fibers. Further polymer composites were prepared using urea-formaldehyde as a novel polymer matrix resin. The silane-treated and untreated fibers along with polymer composites have been characterized by various techniques such as scanning electron microscopy (SEM), Fourier transform-infrared spectrophotometry (FT-IR) and thermogravimetric/differential thermal analysis along with DTG studies. Composites prepared were also subjected to the evaluation of different mechanical, physical, and chemical properties.

“…40 The first stage of mass loss noticed in HSC was around 170 - 220 °C, which can be attributed to degradation leading to 1,4 and 1,6 anhydroglucopyranoside, while the second stage at 342 °C could be considered as being depolymerization at 1,4 glycosidic bond, as previously reported. 41,42 Pyrolysis to lower molecules was found at higher temperatures, which was the third stage. A similar degradation mechanism was also found in HSM except for the appearance of a peak around 260 °C.…”

Grafting of ethylenediamine onto Hibiscus sabdariffa cellulose was achieved via the simple reaction mechanism. The modified Hibiscus sabdariffa cellulose (HSM) and unmodified Hibiscus sabdariffa cellulose (HSC) were characterized using Fourier transformed infrared (FTIR) spectroscopy, elemental analysis, scanning electron microscopy (SEM), X-ray diffraction (XRD), particle size distribution, zeta potential, thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). Both HSM and HSC were also analysed for their water holding capacity, oil holding capacity, swelling capacity, and heavy metal adsorption capacity. The particle size distribution of HSC was found to be monomodal, while that of HSM was bimodal. HSM performed better than HSC in terms of oil adsorption capacity and metal adsorption capacity especially for Pb 2+ and Cd 2+ ions. HSM also performed better than some reported cellulosic materials found in literature. These properties exhibited by HSM present it as a potential resource in the food industry and in treatment of heavy metal contaminated water.
