“…However, the mixing time for binary blends played a significant role. In accordance with the results, Zuo et al report that the addition of SMMA only slightly affects the module elastic for PLA-SMMA-PS and PLA-SMMA-high impact PS (HIPS) [36]. A possible explanation for this could be that by adding the SMMA copolymer at 0 or 10 min, preferred placement is at the interface between the EVA and PLA.…”

In this study, polymer blends with a mechanical property balance based on poly(lactic acid) (PLA), stiff polymer, and elongated polymer were developed. First, the binary blends PLA-elongated polymer [ethyl vinyl acetate (EVA) or polyethylene], or PLA-stiff polymer [polystyrene or poly(styrene-co-methyl methacrylate) (SMMA)] blends were studied using dynamic mechanic analysis (DMA) and analyzed using Minitab statistical software to determine the factors influencing the elongation or stiffness of the blends. Then, ternary blends such as elongation-poly(lactic acid)-stiff, were made from the binary blends that presented optimal performance. In addition, three blends [EVA–PLA–SMMA (EPS)] were elaborated by studying the mixing time (5, 15, and 15 min) and the added time of the SMMA (0, 0, and 10 min). Specifically, the mixing time for EPS 1, EPS 2, and EPS 3 is 5 min, 15 min, and 15 min (first EVA + PLA for 10 min, plus 5 min PLA-EVA and SMMA), respectively. Mechanical, thermal, rheological, and morphological properties of the blends were studied. According to DMA, the results show an increase in elongation at break (εb) and do not decrease the elastic module of poly(lactic acid). Nevertheless, EPS 3 excels in all properties, with an εb of 67% and modulus of elasticity similar to PLA. SMMA has a significant role as a compatibilizing agent and improves PLA processability.

“…In addition, the monomeric units of styrene are miscible with EVA; and methyl methacrylate is miscible with PLA. Zuo et al reported that PLA high-impact polystyrene blends utilize SMMA as a compatibilizing agent due to their higher miscibility with PLA and HIPS [36].…”

“…Usually, the temperature range of heating elements is kept between 170-185 o C. Blends of PLA have been often prepared to provide rigidity in which various kinds of biopolymers are added like polyethylene glycol (PEG), poly(butylene succinate) (PBS), poly(hydroxy acid) (PHA), natural rubber (NR), polycaprolactone (PCL) and poly(hydroxy butyrate) (PHB). These blends are prepared by a melt blending process in which polymers are mixed in a beaker and stirred [18]. Thereafter, the required reinforcement is added to the blend.…”

Being a biodegradable polymer, poly(lactic acid) (PLA) based composites receive greater preference over non-biodegradable plastics. Poly(lactic acid) has to find its place in various applications such as polymer composites, agriculture, biomedical, etc. Polymer composites based on PLA possess comparable mechanical strength, endurance, flexibility and endures future opportunities. Several combinations of natural fibers and filler-based PLA composites have been fabricated and investigated for physical and mechanical changes. Moreover, several biopolymers and compatibilizers are added to PLA to provide rigidity. The paper presents a tabulated review of the various natural fiber/filter-based PLA composites and the preparation and outcomes. In addition, enhancement made by the reinforcement of nano filler in the PLA are also discussed in brief. The significance of PLA in the biomedical application has been discussed in brief. The paper also shed lights in the social and economic aspects of PLA.

“… 3 , 4 It is widely believed that these problems may be largely overcome by substituting traditional petroleum-based plastics with biopolymers derived from nature and degradable synthetic polymers. 5 , 6 Currently, poly(lactic acid) (PLA), a popular biodegradable polymer with good biocompatibility and high mechanical strength, has been widely studied and applied for this purpose. 7 − 9 However, the inherent brittleness and poor ductility of pure PLA limit its wide use, especially in applications where high toughness is required.…”

Here, the high-strength, high-ductility blends of poly(lactic acid) (PLA) with epoxidized soybean oil (ESO) and 3-aminophenylboronic acid (APBA) were successfully prepared via a melt-bending method. The effects of APBA addition on the mechanical and thermal properties, morphologies, and crystallization behavior of the blends were investigated. The results showed that the addition of APBA endowed the PLA/ESO/APBA blends with a good balance of strength and toughness. The yield strength of the PLA/ESO/APBA (90:10:3) blend was 70 MPa, which was 25% higher than that of the corresponding PLA/ESO blend without APBA (56 MPa), while its elongation at break reached 160%, which is greatly superior to that of pure PLA (6.5%). Scanning electron microscopy images showed that the incorporation of APBA significantly improved the compatibility between PLA and ESO, while gel permeation chromatography and rheological analysis suggested the occurrence of complex reactions between the three constituents, which improved the compatibility between PLA and ESO and enhanced the mechanical properties of the blends. Hence, the PLA/ESO/APBA blends possess great potential for application in the manufacture of environmentally friendly degradable plastics.
