In <i>Hevea brasiliensis</i>, periodic ethephon stimulation of tapped trees generates a dilution of the latex, a lower Total Solid Content (TSC) and a lower viscosity, resulting in a longer duration of the latex flow and a higher production of the following tappings. It also increases latex regeneration between two subsequent tappings. These mechanisms induce important changes in the laticifer metabolism and in the cellular genetic expression. Ethephon stimulation has become a major tool for tapping management. However, its excessive use can increase the susceptibility of trees to tapping panel dryness (TPD). A newly formulated ethephon water-based stimulant (RRIM HYDROBEST<sup>TM</sup>, or RHB) is studied. A field trial was set with the clone RRIM 3001, comparing 4 stimulant treatments: ns = non-stimulated = control, ET = Ethephon 5%, MTX = MORTEX 5%, and RHB = RRIM HYDROBEST™ 5%. The production per tree was higher for MTX than for ns and ET, with RHB intermediate between both groups. The dry cut length (DCL) percentage of RHB was lower than that of ns, ET and MTX. Concerning the sucrose content of the latex measured in high-yielding and low-yielding periods, for the control ns alone, sucrose content in the low-yielding period was higher than that in the high-yielding period.

The emergence of AM using elastomers has allowed the production of complex and customised parts with intricate geometries and modified properties as per specific needs of engineers cum designers. For successful 3D printing (3DP), it is crucial to use a material that is suitable for the specific application and printing process. Elastomers are unique polymers that are resilient, flexible and capable of deforming under stress. Fused deposition modelling, stereolithography and selective laser sintering printing are the most common 3DP techniques for elastomers. The use of elastomers in AM is limited due to technological, material and processing constraints. Despite challenges, elastomers have great potential in AM and can be applied in various industries namely automotive, aerospace, healthcare and consumer goods. However, there is a growing interest in expanding the range of elastomers that can be 3D printed. Researchers are experimenting with different approaches to enhance the printability of elastomers such as modifying material composition, material design, optimising printing parameters, control of chemical composition and 3DP techniques. Recent advancements in the structure, properties and printing techniques of elastomers show wide scope for improving their printability. Several elastomeric materials that can be 3D printed include thermoplastic elastomer, thermoplastic polyurethane, liquid silicone rubber, etc. This review paper aims at providing an overview of the current state of AM of elastomers, including the challenges and limitations. It discusses recent advancements and suggests ways to enhance the printability of elastomers in near future, which can help researchers and industry professionals to explore new and unique AM applications.</p></div>","PeriodicalId":662,"journal":{"name":"Journal of Rubber Research","volume":"27 1","pages":"137 - 157"},"PeriodicalIF":1.2,"publicationDate":"2024-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139910062","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The successful dispersion of GO sheets within the ECO matrix has been confirmed by high-resolution transmission electron microscopy and atomic force microscopy. The incorporation of 1.5 vol.% of GO sheets into the ECO matrix enhances the breaking stress and stress at 200% strain values of ECO by 67% and 139%, respectively, which is due to the strong interfacial interactions between the polar groups in ECO and the oxygen-containing functional groups on the surfaces of GO sheets. This general finding is further corroborated by the fact that ECO's glass transition temperature increased from − 18 to − 14 °C with a 1.5 vol% GO content. The initial degradation temperature, the maximum degradation temperature and the percentage residue of ECO consistently increase with the concentration of GO due to the enhanced interfacial interaction between ECO and GO through chemical bonding, which delays the initial degradation by hampering the process of degradation. The uniform dispersion of GO sheets within the ECO matrix, along with improved interactions between GO sheets and ECO, results in the formation of a densely interconnected network of GO layers within the ECO chains. Consequently, this enhances the oil and fuel resistance of the ECO-GO nanocomposites.
