“…(2) the surface grooves distributed on the fiber surface were covered by the waxy substance, reducing the interlocking between jute fibers and matrix; (3) the water molecules penetrated in the waxy substance would be evaporated during the processing of composites, which led to the interfacial defects in composites [7][8][9]. An excellent interfacial compatibility of the composites could ensure the efficiency of stress transfer, which was deemed as the crucial factor to determine the mechanical properties of fiber-reinforced composites.…”

The interfacial compatibility possessed critical effect on the performance of jute fiber-reinforced composites. In order to improve the interfacial compatibility of jute fiber-reinforced polypropylene composites, jute fibers were treated by alkali treatment, ethylenediamine/alkali treatment and acid/alkali treatment. Through analysis by scanning electron microscopy, atomic force microscopy, Fourier transform infrared, X-ray diffraction, surface energy measurement, and tensile strength test, the acid/alkali treatment was deemed as the most efficient method for improving the surface properties of jute fibers among three kinds of surface treatments. The interfacial compatibility of treated fiber-reinforced composites was enhanced significantly, which attributed to the improvement of surface properties of jute fibers. Due to the acidic hydrolysis of acid treatment, the surface energy of acid/alkali treated fibers was increased by 45.58% compared with the control fibers. The tensile and bending strength of acid/alkali treated fiber-reinforced composites were enhanced by 34.80% and 22.53%, respectively. Therefore, the acid/alkali treatment was potential and competitive surface treatment to enhance the interfacial compatibility of jute fiber-reinforced composites.

“…This make natural fibers a good candidate as fillers in composite made by biopolymers. In particular, great attention was paid to the preparation of bio-composite made by PLA and different types of natural fibers such as flax [14][15][16][17], kenaf [18][19][20], jute [21][22][23], hemp [24], palm fibers [25]. However, some drawbacks are needed to be solved for the expansion of these bio-composite like limited mechanical durability, excess water absorption and poor thermal properties [26].…”

According to the European Bioplastics association, in 2017, the so-called bioplastics represented only 2.06 million tons of the 320 million tons of plastics produced annually [1]. The global production capacity is expected to increase up to 2.62 million tons in 2023. This growth is pushed by the demand of more sophisticated biopolymers, new applications and products. From packaging, agriculture, consumer electronics, textile to automotive, bioplastics are used in an increasing number of applications. In fact, biopolymers offer a number of additional advantages if compared to conventional plastics, such as a reduced carbon footprint and additional waste management options. Among bio-based and biodegradable plastics, polylactic acid (PLA) is one of the most interesting ones due to their good mechanical properties, good workability, excellent barrier properties. Therefore, it is a good candidate for the replacement of polystyrene (PS), polypropylene (PP), and acrylonitrile butadiene styrene (ABS) in many applications. However, PLA presents some weak points mainly represented by its low ductility, poor toughness, low glass transition temperature, high sensitivity to moisture and relatively low gas barrier, that limit its use in packaging applications [2, 3]. Indeed, the main

“…1c), due to the removal of amorphous components such as mainly lignin, and metallic ions [17]. Using hydrogen peroxide to bleach the fiber, the hydroperoxide ion that is formed by the dissociation of the peroxide in the alkaline medium is responsible for the discoloration of the fiber, since these ions attack the remaining lignin and cellulose chromophores in the pulp [13].…”

“…Chemical treatments as organosolv can also result in a fractionation of fiber components ant this one can be highlighted as a promising method because it uses an organic solvent [12]. Besides that, bleaching treatment is also carried out to remove the residual amorphous components obtaining a considerable white fiber, where cellulose is mostly present [13]. In this study, organosolv pulping with acetic acid and bleaching with sodium hydroxide and hydrogen peroxide were carried out for Imperata brasiliensis grass, an invasive native species of grass, with the aim of improving its thermal properties and surface aspect for later uses as a reinforcement to polymeric composites materials.…”

The development of new materials has been occurring in order to obtain solutions environmentally more effective. In this context, natural fibers have been used as reinforcement in polymer matrix composites, since they present low density and biodegradability. In the present work Imperata brasiliensis grass was chemically treated by acetosolv treatment using a solution of acetic acid 93 wt% at 110 °C, under reflux, using hydrochloric acid solution 0.3 wt% as catalyst, and bleached with a 1:1 solution of NaOH 4% (w/v) and H2O2 30% (v/v) at 70 °C for 3 h. Untreated and treated fibers were characterized by thermogravimetric analysis (TGA/DTG) and scanning electron microscopy (SEM) and also the color changes after each chemical treatment were considered. According to the results of TGA, the thermal stability of the fiber has increased, comparing untreated and bleached fibers. TGA results also showed the removal of some peaks which is related to the removal of amorphous constituents, a consequence that was also observed trough color analysis. Furthermore, SEM micrographs indicates a defibrillation of fiber after each chemical treatment, a result that can upgrade the anchorage between fiber and matrix and increase subsequent properties of the composite.
