In fact, the aging process is a well-known challenge in rubber materials, as it affects their properties and, in turn, their service life. This makes this research item particularly intriguing. As these materials have potential applications in various engineering fields, obviously it would be of great interest to understand their degradation under real-life conditions. In this context, considerable efforts have been made to study their multi-physical properties under synergistic aging environments (e.g., moisture, thermal, oxygen, aggressive fluids, hygrothermal, thermo-oxidative, photo-oxidative,…). The current review paper sheds light on the degradation mechanisms of polymer rubbers and aims to provide a detailed insight into potential strategies to improve their durability. Interestingly, an in-depth analysis of the synergistic aging effects on rubbers is provided, highlighting the resulting microstructural modifications and changes in physico-chemical and mechanical properties. Likewise, the predictive models used to estimate the service life of rubber materials, are assessed. More importantly, the future directions for improving the durability of polymeric rubbers are critically discussed, with a view to extending their service-life under optimum performances. Finally, a detailed overview of the emerging applications of rubbers is presented. This review is intended to provide new insights into the durability of rubber materials to stimulate new research. It seeks to compile and compare research conducted over the past two decades, establishing a reference framework for future investigations.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture><span>The alternative text for this image may have been generated using AI.</span></div></div></figure></div></div>","PeriodicalId":601,"journal":{"name":"Iranian Polymer Journal","volume":"35 6","pages":"1317 - 1353"},"PeriodicalIF":2.8,"publicationDate":"2025-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148021026","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this composite faces challenges related to high moisture absorption, as hemicellulose limits the roughness of the fiber, and reduced load-bearing capacity influences the mechanical characteristics of the composite. Current research objectives are enriching the quality of fiber, reducing the moisture absorption behavior and enhancing the mechanical properties of polypropylene (PP) composite made with 15% (by wt) abaca natural fiber (ANF), which is treated with 5% sodium hydroxide chemical/amino silane and different weight percentages (1, 3 and 5% by wt) of nanosilicon carbide (SiC) particles via hand layup assisted hot compression mold technology with an applied force of 100 MPa. The influence of composite processing on microstructural behavior is analyzed using a high-resolution transmission electron microscope, which reveals that the fibers and nano-SiC are evenly distributed in the PP matrix with effective interfacial bonding. The PP-based hybrid nanocomposite, comprising 15% (by wt) ANF and 5% (by wt) nano-SiC, demonstrated optimal functional characteristics, including a reduced water absorption rate. Specifically, the PP/15% (by wt) ANF/5% (by wt) nano-SiC hybrid nanocomposite exhibited a maximum flexural strength of 87 MPa, a high tensile strength of 76 MPa, a slight improvement in impact strength (5.2 kJ/m<sup>2</sup>), reduced elongation (6.1%), high hardness (48 HV), and low moisture absorption (4.1%).

This paper provides a complete overview of the global landscape for advancing and using AM techniques. The review focuses on the technical elements of various 3D printing processes and their critical role in producing precise 3D printed structures in diverse industries. A brief introduction to polymer-based composites and their applications is given. Besides, it explores the available knowledge of AM and highlights the most relevant technologies used for the fabrication of polymer-based composites.
