“…The recorded results are close to the values recorded by Nabinejad et al [38], which report a degradation of lignin from 230 to 500 °C. These results may also reveal a similar purity rate of these two fractions.…”

“…Based on Fig. 1 and results previously obtained by the authors [3] it can be concluded that HDW washing is more effective than methanol with the flexural strength and modulus being 8.00% (60.3-65.13 MPa) and 30.9% (2.91-3.81 GPa) higher, respectively, compared to methanol washed samples. Furthermore, sonication was noted to improve the flexural strength of the HDW-US composites by 10.0% (71.4 MPa) compared to the HDW case with a similar trend being observed for flexural modulus with an 8.4% increase to 4.13 GPa.…”

It has been previously noted that the surface porosity and roughness of hydrophilic OPS particles could be enhanced by washing with methanol, which led to improved wettability by the hydrophobic polymer matrix .…”

“…These results are consistent with a previous study on the effect of alkali concentration on the mechanical properties of Borassus fruit fibers which indicated that the maximum tensile properties of the fibers were attained with the maximum amount of α‐cellulose, which itself was achieved for an optimum period of time (8 h) at 5% alkali treatment with the properties subsequently decreasing at more than the optimum time. This could also be attributed to the fact that the existence of surfaces impurities on the OPS powder, which has a significant effect on reducing the mechanical properties of OPS‐UP composites, were removed by chemical treatment . The effect of chemical treatment on the removal of chemical molecules is investigated further in sections Fourier Transform Infrared Spectroscopy (FT‐IR) and Thermal Behavior Study of OPS by Thermogravimetric Analysis.…”

“…It has been previously reported that the decrease in mass residue for washed natural filler is attributed to the removal of impurities and water‐soluble polysaccharides present on the surface of the filler. In light of this, mass residue in the char yield may be an effective indicator of impurity removal due to washing.…”

The effect of water and alkali treatment on the thermal decomposition of oil palm shell (OPS) together with the mechanical performance of polyester composites reinforced with treated OPS has been presented in this work. Treatment of OPS with cold/hot distilled water and cold alkali treatment were found to improve the tensile and flexural strength of the resulting composites although the highest mechanical performance was noted with the use of sonication in hot distilled water. On the other hand, hot alkali treatment was found to produce a composite mechanical performance similar to that of the hot distilled water treatment with sonication. FTIR tests indicated that adsorbed water molecules together with some parts of the hemicellulose and lignin were removed by the treatments. Thermogravimetric analysis and scanning electron microscopy of the treated OPS with hot alkali (1%–9% concentration) showed that the mechanical performance reach a peak at 7% alkali concentration with a further increase in concentration resulting in a significant lignin mass loss and decrease in mass residue of the OPS. This trend was attributed to the higher alkali concentration removing hemicellulose as a binder for the cellulose and lignin which resulted in debonding between the filler and matrix components of the OPS and hence a deterioration in fiber structure and resulting poor composite mechanical performance. Therefore, it was concluded that the optimum concentration of alkali treatment required for maximum mechanical performance of natural filler reinforced polymer composites can be obtained simply from thermogravimetric analysis.
