“…In addition, the presence of TMS promoted better fiber-matrix interfacial interactions, also contributing to the higher tensile modulus. According to Eng et al (2014), the tensile modulus of methacrylate silanetreated oil palm mesocarp/polylactic acid/polycaprolactone/nanoclay biocomposites was higher than untreated composites. Figure 9 shows the elongation at break of control and TMS-treated LLDPE/KNF/PVA composites at different KNF loadings.…”

“…12. Both control and composites with TMS showed characteristic peaks within the range 3200 to 3400 cm -1 (hydroxyl group (O-H) stretching), peaks within the range of 2900 to 2700 cm -1 (CH2 and CH bending), peaks within the range 1600 to 1645 cm -1 (adsorbed water in cellulose or carboxyl/ester groups (C=O) of hemicellulose), and peaks within the range 1460 to 1465 cm -1 (CH2 bending) (Majid et al 2010;Pang and Ismail 2013;Pua et al 2013;Eng et al 2014). However, the spectrum of TMS-treated composites showed a decreased intensity at peak range of 3200 to 3400 cm -1 .…”

“…Majid et al (2010) has reported the similar findings in the compatibilization of LDPE/TPSS-kenaf fiber composites using PE-g-MA compatibilizer. The spectra of both the control composites and TMS-treated composites displayed a strong peak around 1750 cm -1 , which corresponded to carbonyl stretching (C=O) (Rangel-Vazquez and Leal-Garcia 2010; Eng et al 2014). The carbonyl peaks are 1745 cm -1 and 1750 cm -1 for control composites and TMS-treated composites, respectively.…”

“…According to Eng et al (2014), when there is an interaction in the polymer composites, shifting of peaks in IR spectra may occur. Meanwhile, Majid et al (2010) claimed that polymer composites with good compatibility will result in greater correlative peak shift and change in peak shapes.…”

Tensile Properties, Water Resistance, and Thermal Properties of Linear Low-Density Polyethylene/Polyvinyl Alcohol/Kenaf Composites: Effect of 3-(trimethoxysilyl) propyl Methacrylate (TMS) as a Silane Coupling Agent

aComposites containing linear low-density polyethylene/polyvinyl alcohol and various loadings of kenaf fiber were prepared using a Haake internal mixer. The loading of kenaf fiber varied from 10 to 40 parts per hundred resin (phr). The coupling agent 3-(trimethoxysilyl)propyl methacrylate (TMS) was evaluated for its effect on the processing torque, tensile properties, morphology, water resistance, and thermal properties of the composites. Composites without TMS were used as the control. The composites made from TMS-treated kenaf yielded higher stabilization torque, tensile strength, tensile modulus, water resistance, and thermal properties than the control composites. The improvements were attributed to the coupling effect of TMS.

“…Therefore, modification is needed to improve fiber/matrix adhesion. Recently, modification of OPMF by superheated steam (Nordin et al 2013), alkaline peroxide , or silane coupling agents (Eng et al 2014b) was successfully conducted by our research group. Huda et al (2008) modified kenaf fibers using alkalization and silane treatments and then blended them with polylactic acid (PLA).…”

Effects of modifying oil palm mesocarp fibers (OPMF) by methacrylate silane on polylactic acid (PLA)/ polycaprolactone (PCL)/clay/OPMF hybrid composites were investigated. The composites were prepared by a melt blending technique and characterized by dynamic mechanical analysis (DMA) and scanning electron microscopy (SEM). The silane-treated OPMF hybrid composites showed better tensile strength, tensile modulus, and elongation at break than unmodified OPMF hybrid composites. DMA analysis showed an increase in storage modulus when silane-treated OPMF was added to a hybrid composite. The loss modulus curve showed that the incorporation of silane-treated OPMF into a hybrid composite shifted the two glass transition temperatures (Tg) of composites closer to each other. The low tan δ peak indicated good fiber/matrix adhesion for the silane-treated OPMF hybrid composites. SEM micrographs revealed that silane-treated OPMF hybrid composites showed better fiber/matrix adhesion than unmodified OPMF hybrid composites because of absence of gap between silane-treated OPMF and the matrix in the composite.

Poly (lactic acid) (PLA) is a renewable and biodegradable polymer with high modulus, high strength but low toughness. Blending PLA with plant fiber has been believed an available strategy to improve the toughness of PLA. PLA/Flax composites were fabricated by extrusion and injection molding processes. The flax fiber surfaces were modified before blending to improve the compatibility, and the chemical structures of both untreated and treated fiber were characterized by Fourier transform infrared spectroscopy. Results of mechanical test showed that the impact strength and elongation at break of PLA/Flax composites were remarkably higher than PLA. The impact fractures of PLA/Flax composites were also observed by scanning electron microscope. The results showed uniform dispersion of fibers in PLA matrix and good compatibility between treated fibers and PLA matrix. Moreover, it can be observed that crazing propagation was hindered by fibers and transcrystalline developed along fibers by polarized optical microscope. Differential scanning calorimetry analysis was carried out to study the crystallinity of PLA and it was found that incorporation of fiber improved the crystallinity of PLA. The toughening mechanism of PLA/Flax composites was discussed according to the results.
