“…A study of the compatibilization effect of three types of epoxy functionalized POSSs with PLA/PBAT blends was done by Kilic et al [ 70 ] The potential of epoxy‐POSS types to compatibilized the immiscible PLA/PBAT blends was investigated as a function of PBAT molecular weight (11,000 and 54,000 Dalton of number average of molecular weight). Thermal properties of the prepared samples were investigated by DSC analysis.…”

The production of petroleum‐based polymers in huge amounts is perilous for our ecosystem and oil reserves. The use of biodegradable polymers instead of synthetic polymers for various commodity, engineering, and biomedical applications remains the overriding concern of the researchers in last decades. Although poly(lactic acid) (PLA) is considered to be the most befitting substitute for conventional petroleum‐based products because of its superlative mechanical properties, material & processing cost, and non‐toxicity, they have some consequential limitations for various applications because of their slow rate of crystallization, low thermal stability, high brittleness, and low toughness. To overwhelm these deficiencies during the last two decades, researchers have developed various techniques to tailor the properties of PLA, that is, blending with other polymers or using additives such as nanofillers. Among all the nanofillers, for example, carbon nanotubes and organoclays, polyhedral oligomeric silsesquioxanes (POSS) was found the most promising nanofiller because of its organic and inorganic nanostructure and fine dispersion into PLA matrix. This article reviews all the investigations relevant to POSS incorporation into PLA or blends of PLA with other polymers to compare the mechanical, morphological, and physical properties of the ameliorated composites and the neat PLA.

“…[8] PLA has been blended with poly(ε-caprolactone) (PCL), [9][10][11][12][13] poly((butylene succinate)-co-adipate), [14][15][16][17] poly(butylene succinate), [18][19][20][21] and poly(butylene adipate-co-terephthalate) (PBAT). [17,[22][23][24][25][26][27][28][29] Although blending has been found to be an effective way to enhance the ductility and thermal properties of PLA, the immiscibility of the blend could cause the formation of phaseseparated morphologies depending on the blend ratio, molecular weight, interfacial tensions, and processing conditions. [22,[30][31][32] It has been shown that different morphologies, and thus different properties, can be obtained if these parameters are varied.…”

“…Importantly, several key factors, such as the nanoparticle/polymer interaction, surface tension, viscosity ratio, molecular weight, blending sequence, mixing time, and type of mixer, play an important role in the localization of nanoparticles inside immiscible blends. [ 28,42,47,54,55 ] For instance, our previous work revealed that more CNTs could migrate to the PLA/PVDF interface when an internal mixer was used than when the nanocomposites were prepared using a twin‐screw extruder. [ 42 ] Another study showed that nanoclay particles are dispersed through the entire PLA/PBAT blend when they are processed through a twin‐screw extruder.…”

This article reports the effects of the characteristics and selective localization of nanofillers on the morphology development and rheological properties of melt-processed polylactide/poly(butylene adipate-co-terephthalate) (PLA/ PBAT) blend composites. Four types of nanofillers (1 wt%) are used: nanoclay (Cloisite30B [C30B]), carbon nanotubes (CNTs), nanosilica, and graphene oxide (GO). Transmission electron microscopy studies reveal that C30B is localized mainly at the PLA/PBAT interface, whereas silica, GO, and CNT are localized in PBAT droplets, although some CNTs also appear toward the interface inside the PBAT. Despite their selective localization inside the PBAT, CNTs are found to be the most effective particles for droplet size reduction, whereas silica nanoparticles are ineffective. The CNT bundles recoil during melt blending, and eventually, their breakage facilitates droplet breakup. The effects of nanofiller localization and annealing under dynamic shear on the blend morphologies are also explored through rheological analysis. The results show an anomalous relationship with the morphologies of the composites. It is also found that both coalescence and thermal degradation are involved in the annealing process of the blends. Interestingly, the CNT-filled composites may have been transformed into co-continuous-like structures during annealing, unlike the other blends studied here.

“…We found that epoxy-POSS nanoparticles enhanced the interfacial interaction much more efficiently between PLA and PBAT with lower molecular weight. 33 In another study, 34 we investigated the compatibilization effect of epoxy-POSS nanoparticles for PLA/PBAT system. It was observed that mechanical properties such as Izod impact strength and elongation at break of PLA/PBAT were significantly improved when 0.5 wt% mono-epoxy-POSS was incorporated to the PLA/PBAT.…”

In this study, the compatibilization effects of triglycidylisobutyl polyhedral oligomeric silsesquioxane (TEpPOSS) on biodegradable poly(lactic acid) (PLA)/thermoplastic polyurethane (TPU) blends were investigated. All blends were prepared via melt blending and PLA/TPU (80/20, 70/30, 50/50 wt%) ratio was selected as the experimental parameter. In order to predict the selective localization of TEpPOSS thermodynamically, wetting coefficient were determined by means of surface energy measurements. Morphological analyses were carried out by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Moreover, rheological, mechanical, thermomechanical and thermal properties of the blends were performed via rheometer, universal tensile tester, dynamic mechanic analyses and differential scanning calorimeter (DSC), respectively. Morphological test results revealed that TEpPOSSs were mostly located at the interfaces of the PLA and TPU phases. According to the rheological studies, the interfacial interactions between PLA and TPU were improved with the addition of TEpPOSS, which resulted from the potential reactions between epoxy-carboxylic acid and/or epoxy-hydroxyl functional groups. The addition of TEpPOSS enhanced the mechanical properties of PLA/TPU blends. DSC test results revealed a decrease in the glass transition temperatures of PLA in the presence of TEpPOSS, which was an another indication of improved compatibility between PLA and TPU.
