“…High fiber content is responsible for poor fiber matrix adhesion. Similar results are reported elsewhere for jute/polyester amide composites [14].Chemical treatment of jutefiber plays an important role on its mechanical properties. HEMA and BPO treated composites have higher values of BS than that of untreated composite.…”

Jute fiber reinforced low density polyethylene (LDPE) composites (10-30% fiber, by weight) are prepared by compression molding. Tensile strength (TS), bending strength (BS) and bending elongation (BE) of the composites are increased over LDPE. Jute fiber is treated with monomer (2-hydroxyethyl methacrylate, HEMA) along with two different initiators in methanol solvent. Jute fibers are soaked with 10% HEMA+2% Irgacure-184 (F1-Formulation) and 3% HEMA+2% benzol peroxide (F2-Formulation) and dried at 80ºC for 2 hours then composites are fabricated by compression molding. It is found that due to chemical treatment of the jute fibers, a significant improvement of the mechanical properties of the composites are happened (56% TS, 30% BS and 35% BE) compared to the LDPE. 3%HEMA+2% benzol peroxide treated jute composites found better mechanical properties compared to 10%HEMA+2% Irgacure-184 treated jute composites. Dielectric constant and loss tangent of the composites are increased with increasing temperature up to a transition temperature and then decreased, finally reached to plateau. Scanning Electron Microscopic (SEM) analysis of the fracture side of the composites are carried out and supported better fiber-matrix adhesion due to the chemical treatment.

“…Benzol peroxide is an oxidizing agent and it can ionize quickly than Irgacure-184. HEMA treatment of the jute fibers decreases the hydrophilic nature of the jute which attributes higher TS over the control composites [14].…”

“…7 Several researchers have attempted to improve the interfacial bonding between the natural fibers and the matrix by altering the hydrophilic nature of the fibers. Several methods to achieve this include chemical treatment, [8][9][10][11][12][13][14] acetylation of the hydroxyl group of the fibers, 15 post-treating with urotropine and urea 16 and the well-known process of alkali treatment. 10,[14][15][16] Alkali treatment has the potential of improving fiber strength by removing lignin, hemicellulose, and pectin.…”

To improve the adhesion and wetting between the abaca fibers and matrix, the surface of abaca fabric was modified using plasma polymerization. Different plasma exposure times were conducted to determine the effect of plasma treatment on the properties of the composites. A combination of plasma and other surface modification processes was also investigated to determine whether double treatments could further enhance the properties of these composites. Combined treatments involve plasma polymerization of the fabric after pretreatment with one of the following surface-modification reagents: a) γ -methacrylopropyltrimethylsilane, b) triethoxyvinylsilane, and c) 2% w/w NaOH (aq).The abaca fabric/unsaturated polyester composites were fabricated using the vacuumassisted resin transfer molding (VARTM) technique.SEM results showed that 10 to 20 seconds plasma treatment gave the right amount of surface roughness for maximum fiber and matrix adhesion leading to improved mechanical properties of the composites. Longer plasma treatment time and double treatment however resulted in composites with lower mechanical properties. Although the composite with alkali and plasma-treated fabric showed the lowest mechanical properties it exhibited the lowest water uptake in both distilled water and brine solution.

“…23,25,26 There have been many research reports of the treatment of alkali on cellulose fibers and applications of these in polymer composites. 2,[10][11][12][13][14][15][16][17][27][28][29][30][31][32][33][34][35] For chemical treatment of cellulose, the focus has been mainly on changes of characteristics of cellulose surface by removing impurities on the cellulose fiber, which results in more hydroxyl groups (active sites) exposure on the cellulose fiber. [10][11][12][13][14][15][16][17] There have been no published reports uses of nano-cellulose filled polymer composite for characterization because the nano-cellulose fibers has been typically obtained in lab scale thus the yield was so small not enough to put into polymer matrix.…”

“…When alkali removes impurities on natural fibers, more active sites, hydroxyl groups, which can react with other chemicals such as coupling agents or polar character homogenizers, are exposed to polymer matrix. Further treatment of nano-kenaf with NaOH triggers reaction between accessible -OH groups of the kenaf and -OH groups of the alkali according to following proposed chemical reaction 28,[33][34][35] as shown in eq. (3).…”

The surface of nano-kenaf containing cellulose fibers was treated with alkali (NaOH) and their effects on the physical properties of the polypropylene (PP) composite were investigated. The treatment of alkali on the fibers increased the melt flow index (M.I.), elongation%, and impact strength, while it decreased the tensile strength, flexural modulus and heat deflection temperature (HDT) of the compound compared to the untreated one. It seemed the alkali treatment on the nano-kenaf fiber changed the character of the fiber due to removal of impurities and chemicals on the surface and resulted in decreased interfacial adhesion between the nano-fiber surface and the PP matrix and changed the character of the PP.
