“…A new generation of hybrid (both organic and inorganic) nanoparticles, such as polyhedral oligomeric silsesquioxane (POSS) like materials, have received much interest. POSS may be efficiently integrated into polymers using typical processing processes such as copolymerization, grafting, and/or melt mixing 16,17 . Increased mechanical strength and oxidation resistance, as well as decreases in flammability, heat evolution, and change in viscosity values during processing, are just a few examples of the significantly improved properties that can be achieved by adding POSS or its derivatives to polymers 6,10,17–22 .…”

This study focuses on the compatibilization of PLA/poly(butylene succinate) (PBS) blends using mono‐ and multi‐epoxide POSS (MoEpPOSS and MuEpPOSS) nanoparticles, from a rheological point of view for the first time in the literature. The addition of PBS to PLA decreased the complex viscosity, storage modulus, and loss modulus, indicating weak interactions between polymers. However, the incorporation of MoEpPOSS and MuEpPOSS increased the complex viscosity and storage modulus due to the formation of long polymeric chains or complex polymeric structures through interactions between the epoxide groups of POSS and the end groups of the polymers. The effect was more significant with MuEpPOSS because MuEpPOSS has multiple epoxide groups in its cage structure, leading to stronger interactions with the polymers. POSS incorporation resulted in semicircular and arc‐shaped curves in the Cole‐Cole plots, indicating better dispersion, phase homogeneity, and compatibility. The introduction of POSS also influenced the dynamic loss tangent (tan δ) versus frequency (ω) plot. When POSS was introduced, the tan δ peak decreased and shifted to a higher frequency, indicating improved compatibility, and enhanced interfacial adhesion. These findings indicated that the addition of epoxy‐POSS nanoparticles can effectively compatibilize PLA/PBS blends and enhance their rheological properties, potentially improving their overall performance for various applications.

“…Blending two or more polymers has become an emerging tool for getting novel and desirable unusual properties, for example, mechanical, thermal, morphological, rheological, and chemical properties. Polymeric hybrids/composites are being used enormously for several valuable products, for example, footwear, medical devices, automotive vehicles, packaging, space vehicles, and so forth 26,27 . Blends of rubbery (elastic polymers) and comparatively stiffer plastics form othermoplastic elastomers (TPEs).…”

Various blends and composites have been prepared during the past decade to address limitations, including the poor mechanical properties of polymers, or to balance out the high cost of synthetic polymers. Rubber‐based thermoplastic blends and composites are being developed to attain improved performance and balanced qualities for usage in a variety of industries, including automotive, packaging, home products, space technology, and biomedical. Thermoplastics can be produced via standard manufacturing procedures and have outstanding qualities like low density, good chemical resistance, and heat resistance. However, rubbers are being used because of their elastic attributes, including their resilience, impact resistance, and good tear strength. These two materials work well together when blended or combined. In this article, an effort was made to narrow the gap between rubbers and thermoplastics. The mechanical, rheological, and morphological properties of the rubber/thermoplastic blends and composites/nanocomposites containing various types of conventional fillers and nanofillers were discussed comprehensively. Blends of these materials can provide too easier melt processing as well as financial benefits. The flexible nature and damping properties of rubber and better thermal stability and thermoplastic processability contributed to the development of high‐performance rubber/thermoplastic composites with better ductility, impact strength, and stiffness. Rubber reduced the high brittleness of thermoplastics because of its resilience and damping properties. In contrast, the poor processability and weak chemical resistance of rubbers were overcome via better processability and higher stiffness of thermoplastics. Rubber‐based thermoplastic composites and nanocomposites have been reported to offer greater flexibility, better processing, high impact strength, and chemical resistance.Highlights The properties of rubber/thermoplastic blends were discussed in this article. More recent advancements in rubber/thermoplastic blends were evaluated. Morphological properties depend on the rubber/thermoplastic blend ratio. The addition of reinforcements affects the rheological properties. Dispersion of additives and blend ratio influence the mechanical properties.

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.
