“…The excess compatibilizer dispersed in the binary blends has a tendency to agglomerate, thus, reducing its T m . This explanation was in line with the justification given in another publication [ 51 ]. The presence of a single peak for T m and T c for LDPE/PBS/PE–g–MA was discussed above.…”

It is of significant concern that the buildup of non-biodegradable plastic waste in the environment may result in long-term issues with the environment, the economy and waste management. In this study, low-density polyethylene (LDPE) was compounded with different contents of poly(butylene succinate) (PBS) at 10–50 wt.%, to evaluate the potential of replacing commercial plastics with a biodegradable renewable polymer, PBS for packaging applications. The morphological, mechanical and thermal properties of the LDPE/PBS blends were examined in relation to the effect of polyethylene–graft–maleic anhydride (PE–g–MA) as a compatibilizer. LDPE/PBS/PE–g–MA blends were fabricated via the melt blending method using an internal mixer and then were compression molded into test samples. The presence of LDPE, PBS and PE–g–MA individually in the matrix for each blend presented physical interaction between the constituents, as shown by Fourier-transform infrared spectroscopy (FTIR). The morphology of LDPE/PBS/PE–g–MA blends showed improved compatibility and homogeneity between the LDPE matrix and PBS phase. Compatibilized LDPE/PBS blends showed an improvement in the tensile strength, with 5 phr of compatibilizer providing the optimal content. The thermal stability of LDPE/PBS blends decreased with higher PBS content and the thermal stability of compatibilized blends was higher in contrast to the uncompatibilized blends. Therefore, our research demonstrated that the partial substitution of LDPE with a biodegradable PBS and the incorporation of the PE–g–MA compatibilizer could develop an innovative blend with improved structural, mechanical and thermal properties.

“…Moreover, the addition of 7 phr of the PE–g–MA causes gradual structure weakening in the blends with the formation of agglomeration that promotes lower interfacial adhesion between the phases and subsequently decreases the TS [ 51 ]. The introduction of PE–g–MA of 3 phr did not strongly affect the TS of 60–90 wt.% LDPE blends.…”

“…On the other hand, tensile strength decreased by increasing the loading level of APOSS. Salleh et al 38 reported the similar result for the kenaf fiber/high-density polyethylene/maleic anhydride compatibilized composites. The reduction in the tensile strength may be due to the presence of agglomeration with the addition of excess compatibilizer.…”

The aim of this study was to investigate the effects of different compatibilizers on the properties of polyamide-sized carbon fiber-reinforced poly(phenylene sulfide) composites. The composites were prepared by using melt blending and injection molding methods by using three different compatibilizers at various loading levels. The characterization of composites was performed by Fourier transform infrared spectroscopy, tensile test, dynamic mechanical analysis, differential scanning thermometer, thermogravimetric analysis and scanning electron microscope. According to tensile test results, the highest increment in tensile strength and strain at break values of composites was observed with the addition of Joncryl. According to scanning electron microscope and dynamic mechanical analysis results, the best interfacial adhesion between carbon fiber and poly(phenylene sulfide) was obtained by using Joncryl as the compatibilizer.

“…These results are comparable to those work which ulitilized grafted co-polymer as a third component. 48,49 Addition of maleic anyhdride beyond 2% results in decline of tensile properties in composite. This may be due to the saturated situation which leads to accumulation of excess MA around the fibers causing self-entanglement and slippage rather than grafting.…”

The interphase adhesion plays key role in the performance of composites. The commonly employed strategies include blending with an external compatibilizer or utilizing chemical grafting followed by purification and copolymerization. Here, we showcase a reformed and simple approach in the fabrication of chemically functionalized, self compatibilized composites [PE-TCF5%-MA2%] by insitu grafting of maleic anhydride in the polymer melt, followed by the reactive compatibilization of treated short coir fiber. Microstructural analysis of the composites revealed enhanced fiber/matrix adhesion. The improved mechanical, viscoelastic, and thermal properties of composites can be attributed to new interfacial bond formed, which was confirmed by Fourier transform infrared [FTIR] studies. PE-TCF5%-MA2% exhibited approximately 74% and 25% improvement in tensile strength compared to untreated (PE-UCF) and treated (PE-TCF) fiber composites respectively. Dynamic mechanical analysis of composites displayed similar trend with highest value of storage modulus recorded for PE-TCF5%-MA2%. Final decomposition temperature of all composites was shifted to higher side. Peak degradation temperature was increased with a marginal increase of residual char. Together with the goodness of agro-based fiber and feasiblity of this low cost method suggests the potential of PE-TCF-MA toward bulk industrial prodution of composite panels.
