Yet, there has been increased research into eco-friendly alternatives to petroleum-based plastic packaging owing to concerns about the adverse environmental effects of the materials used traditionally. Being plentiful, sustainable, biodegradable, and inexpensive, starches have become one of the most exciting biopolymer candidates for research. Thermoplastic starch, prepared through plasticization of native starch with water and small molecules called plasticizers, is one of the candidates for food packaging. In this review, the potential applications of thermoplastic starch blends in food packaging are considered based on the analysis of the influence of plasticizers on thermoplastic starch and mixing of thermoplastic starch with common and biodegradable polymers. Particular consideration is given to the mechanical, physical, thermal, and barrier properties of thermoplastic starch blends and the applicability of these blends in food packaging. Based on the findings from the reviewed literature, it is evident that the addition of polymers such as polyethylene, polypropylene, polystyrene, polyvinyl alcohol, and polylactic acid to thermoplastic starch significantly increases their mechanical, flexible, processing, and barrier properties. It has also been observed that despite being environmentally friendly due to their increased biodegradability and low dependency on synthetic plastics made from fossil sources, challenges remain in terms of moisture sensitivity, blend compatibility, thermal stability, and commercialization. Taking all factors into account, there is much potential for the utilization of thermoplastic starch blends in sustainable food packaging applications. Further advances in blend modification and manufacturing processes will serve to accelerate their commercial acceptance and contribute to the development of environmentally sustainable packaging systems.</p></div>","PeriodicalId":592,"journal":{"name":"International Journal of Mechanical and Materials Engineering","volume":"21 1","pages":""},"PeriodicalIF":2.0,"publicationDate":"2026-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1186/s40712-026-00533-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148986966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among candidate materials, the AlSi10Mg alloy is particularly well suited for additive manufacturing (AM) due to its excellent processability. However, the rapid solidification inherent to the AM process leads to forming a supersaturated solid solution in the AlSi10Mg matrix, which markedly reduces its thermal conductivity. In this study, an aging heat treatment was employed to promote the precipitation of solute phases from the supersaturated solid solution, thereby enhancing the thermal conductivity and mechanical properties of the AlSi10Mg alloy. The results indicate that aging at 200 °C for 10 h effectively promotes the precipitation of Si particles within the α-Al matrix. This treatment yields a notable tensile strength of 350 MPa and a high thermal conductivity of 173.70 W·m⁻¹·K⁻¹, representing a 44.3% improvement over the as-built state. Thus, we achieved a synergistic enhancement of both thermal and mechanical properties. The improved thermal conductivity is attributed to reduction of solid-solution Si in the matrix and the refinement of precipitated Si particles.

This comprehensive review investigates the use of surface roughness, contact angle dynamics, and material selection in regulating the anti-icing efficiency of SHCs. The relationship between droplet behavior and surface morphology was investigated in terms of the Cassie-Baxter and Wenzel wetting conditions and their effects on ice nucleation and adhesion. The composition of materials such as fluorinated polymers, metal oxides, and hybrid nanocomposites is considered in terms of their contribution to the durability of the surface used and reduced surface energy. In addition, recent developments in fabrication processes, including electrodeposition, electrospinning, and sol–gel, are discussed within the context of scalability, mechanical strength, and environmental friendliness. Problems with mechanical wear, damage from sunlight, and staying stable in tough conditions are discussed. Recent advances in self-repairing and temperature-sensitive coatings are also discussed. The adoption of hybridization of superhydrophobicity with photothermal and electrothermal capabilities is emphasized as a way forward to develop durable and energy-efficient anti-icing capabilities.
