“…This shows that the addition of natural fiber, durian skin fiber can improve the tensile strength of the polymer matrix [4]. According to Abu Hassan et al, epoxidized palm oil (EPO) is added as plasticizer has proven to improve the mechanical properties of PLA [1]. However, in this experiment, the tensile strength of PLA/DSF/EPO biocomposite foamed is slight lower than PLA/DSF biocomposite foamed which this might due to the agglomeration of fiber that happen between PLA and DSF in presence of EPO.There are many reports has mention about the effect of SCCO2 on polymer, as mention by Bocz et al the SCCO2 contribute to plasticized of polymer during the treatment [6].…”

“…Polylactic acid (PLA) has been acknowledged among the biopolymers as the most compromising biodegradable material due to its ability to biodegrade easily, hence making it one of the most environmentally friendly thermoplastic polyesters with unique properties [1]. PLA has become the most compromising biodegradable material among the biopolymers, in which the fraction of enantiomers in the polymer determines the physical characteristics of the material, so that it can provide a different level of crystallinity, temperature melting, and also temperature of the glass transition [2,9].…”

The use of PLA as a green substitute for conventional plastics has increased considerably as a result of increased awareness of the environmental effect of the use of petroleum-based plastics. However, some of the PLA properties including brittleness and sensitivity to high temperature and humidity, greatly restrict its application. The addition of reinforcement of low-cost natural fibres and foaming are considered to overcome the above disadvantages since it can improve some of PLA’s processing. This paper reported the effects of supercritical carbon dioxide (SCCO2) on the tensile strength of PLA biocomposite films produced via solution casting method. The biocomposite films underwent supercritical carbon dioxide (SCCO2) treatment at temperature of 40°C and pressure at 200 bar. The tensile strength showed that the PLA biocomposite foamed has improved by 16.18%. This is due to a good adhesion interfacial between fiber and polymer matrix. A simulation on tensile strength of the biocomposite foamed was also conducted using COMSOL Multiphysics software. The tensile strength resulted from this simulation is similar to the experimental value. Therefore, the experimental value is valid and satisfy. This also showed that SCCO2 treatment significantly improved the properties of PLA biocomposite films which could be an alternative in packaging industries.

Blending of Low-Density Polyethylene and Poly(Butylene Succinate) (LDPE/PBS) with Polyethylene–Graft–Maleic Anhydride (PE–g–MA) as a Compatibilizer on the Phase Morphology, Mechanical and Thermal Properties

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.
