PLLA-g-LMWNR (LMWNR – low molecular weight natural rubber) was used as a compatibilizer (1–3 wt %) of poly(L-lactic acid)/deproteinized natural rubber (PLLA/DPNR) blend (95/5 w/w). The LMWNR was prepared using TiO2/ZnO (9 : 1 w/w) and H2O2 as co-catalyst. The obtained LMWNR was grafted with 0–12 wt % maleic anhydride (LMWNR-g-MA) and then with PLLA (PLLA-g-LMWNR). A significant improvement in the mechanical properties of the PLLA/DPNR blend was found in the blend that contained 3 wt % PLLA-g-LMWNR. Scanning electron microscopy showed a decrease in the pore diameter from 5.44 to 1.56 μm. The thermal analysis of PLLA/DPNR blends showed that the Tg value of PLLA phase shifted from 63.1 to 61.4°C. These results confirmed that PLLA-g-LMWNR can enhance the compatibility of the PLLA/DPNR blend.

Polylactic acid (PLA) biocomposites were prepared by melt blending in an internal mixer with various types of rubber. The rubber was 90/10 wt% and was mixed before the addition of kenaf fiber (0 to 20 phr). Natural rubber (NR), nitrile butadiene rubber (NBR), and styrene butadiene rubber (SBR) were used. The effects of different types of rubber and kenaf loading were investigated based on processing torque, water absorption, mechanical properties, and fractured surface morphology. A similar trend in processing torque was observed throughout the composition of biocomposites. The stabilization torque was highest for the biocomposite with NR, followed by SBR and NBR. Water absorption increased as the kenaf loading increased. The polarity of NBR and SBR contributed to higher water absorption in the biocomposites compared to the NR. The strain-induced crystallization phenomenon and higher green strength of NR contributed to the highest tensile strength, elongation at break, and impact strength of the biocomposite compared to the NBR and SBR toughened PLA/kenaf biocomposite. More plastic deformation and less fiber pullout were observed in the fractured surface morphology. However, by increasing the kenaf loading, the mechanical properties decreased for all biocomposites, which was due to poor interfacial adhesion and agglomeration.

The utilisation of waste materials in polymer matrices is gaining attraction due to the growing environmental awareness. In this work, eggshells waste was added into polyvinyl alcohol to produce biocomposite films via solution casting method. In order to enhance the properties of the biocomposite, glutaraldehyde (GA) was incorporated as the crosslinking agent. The effects of GA content on the biocomposite were evaluated in terms of its tensile properties, physical properties and biodegradability. From the tensile test, the optimum GA content was found to be 2 phr as portrayed by the highest tensile strength at this GA content. Further addition of GA deteriorated the mechanical properties of the biocomposite. On the other hand, the water absorption, water vapour transmissibility and biodegradability (via natural weathering and soil burial) of the biocomposite films decreased with GA addition.

ABSTRACT Due to environmental concern and depletion of fossil fuel, research on biopolymer is gaining interest among researchers. Polylactic acid (PLA) is produced from renewable resources. PLA has high tensile strength and high modulus, and it can be processed by using conventional processing methods. However, some properties of PLA limit the usage, such as brittleness, low impact resistance, low thermal stability, and high cost. Overall, the toughening approach of PLA, blending with elastomer has been one of the main focuses. This review paper is intended to provide general information regarding progress made in PLA toughening by an elastomer. Graphical Abstract

Polyvinyl alcohol/palm kernel shell powder biocomposites were prepared by using a solution casting method. To enhance the properties, the crosslinking agent glutaraldehyde (GA) was added to the composition. The effect of the crosslinking agent on the biocomposite was studied based on the change in the tensile properties, physical properties, and biodegradability. The optimum GA content was found to be 2 phr because the tensile properties tended to decrease with higher GA contents. The water absorption percentages and water vapour transmissibility decreased until the GA content reached 2 phr and then increased. It was found that the biodegradability of the film decreased when GA was added.

Polyvinyl alcohol (PVA)/eggshell powder (ESP) were prepared via solution casting method. The effects of gradual replacement of ESP by halloysite nanotubes (HNTs) were investigated based on tensile properties, physical properties and biodegradability. The main objective is to study the effect of hybrid fillers and also to compare the properties of PVA/ESP composite with conventional filler, HNT. The tensile properties decreased with increasing HNT loading. Scanning electron microscopy (SEM) studies showed that agglomeration of filler were present throughout the composites. Due to the presence of hydroxyl group on the outer and inner surface of HNT, the water absorption and water vapor transmisibility were found to increase with increasing HNTs loading. The biodegradability of film filled with HNT is lower compared to the film filled with ESP.
