“…It is worth noting that the loss of superhydrophobicity can be recovered through self‐healing, but this process will affect the stability of superhydrophobic surface. [ 81 ] This method provides the possibility of preparing large‐scale superhydrophobic surface with required repeatability in quality. Based on previous reports, [ 80,81 ] Yan and Liang coated the previously prepared superhydrophobic silicone rubber surface with a layer of mixed solutions containing PDMS, fluoroalkyl silane (FAS), silica particles of different particle sizes, etc., and obtained the superhydrophobic surface after high temperature curing.…”

Silicone rubber materials have excellent comprehensive properties and are widely used in outdoor insulation, aerospace, and other fields. Due to its low surface energy and the appearance of biomimetic superhydrophobic materials, silicone rubber has become one of the popular materials in the field of superhydrophobicity. Superhydrophobic silicone rubber materials play an irreplaceable role in a wide range of applications such as long‐distance high‐voltage power transmission and high‐speed rail transportation. In this paper, research on superhydrophobic materials, including typical fabrication methods, is summarized to provide an overview of the up‐to‐date research state and progress in detail.

“…The multiple stresses present in the environment cause degradation in the polymer and this effect causes aging of the insulator. 12 -14 The same degradation phenomenon is experienced by high-temperature vulcanized rubber (HTV-SiR) when subjected to multiple environmental stresses. 2 These environmental stresses cause a decrease in flash overvoltage, increased leakage current (LC), reduction in electrical characteristics, and loss of hydrophobicity.…”

Multiple environmental stresses produce complex phenomena of aging in polymeric insulators. The main aim of this research is to investigate the improved aging characteristics of silica (SiO2)/alumina trihydrate (ATH) hybrid samples (HSs) in high-temperature vulcanized rubber. For this purpose, three HSs comprising 20% micro-ATH with 2% nano-SiO2 (S2), 4% nano-SiO2 (S4), 6% nano-SiO2 (S6) along with sample-virgin (SV) are subjected to long-term accelerated aging of 9000 h. A special aging chamber is fabricated for the aging process of samples. The aging characteristics of these samples are investigated by measuring leakage current (LC) and hydrophobicity classification (HC) after every weathering cycle. Similarly, Fourier transform infrared (FTIR) spectroscopy is performed to observe the important structural changes over the entire aging time. The dielectric strength of AC is also performed after every 1000 h of aging. Tracking and erosion resistance and mechanical properties are also investigated before and after aging. From the critical investigation, it is observed that HSs possess improved results in all the conducted tests. S2 has the lowest LC and HC values throughout the aging time. Similarly, S6 described the highest breakdown strength at the end of the accelerated aging. In the case of FTIR, it is analyzed that the important wave numbers remain intact for all the HSs in the accelerated aging environment. The loss percentage in the wave number for SV is higher, compared to the HSs. After performing the tracking and erosion resistance test, HSs have superior performance. For some of the mechanical properties, HSs showed improved values. Thus, from the experimental analysis, it is deducted that the sample S2 offers the highest resistance to the aging conditions, compared to the SV and other HSs.

“…Due to the wide application of silicone rubbers as electrical insulators in electrical apparatus, power transmission, and distribution systems, etc. [9,10,11,12,13], the studies on the ageing behaviour of silicone rubbers have mostly focused on weatherability, UV radiation ageing, and dielectric breakdown [10,11,13,14,15]. In contrast, there have been few studies on the deterioration of silicone rubber properties in other applications.…”

Understanding the Effects of In-Service Temperature and Functional Fluid on the Ageing of Silicone Rubber

With an organic/inorganic hybrid nature, silicone elastomers are amongst the most versatile engineering materials, exploited in a wide range of applications either as end-products or in manufacturing processes. In many industrial machines, silicone components are exposed to in-service conditions, such as high or low temperatures, contact with functional fluids, mechanical loading, and deformations, which can adversely affect these components and reduce their lifespan, leading to machine failure in turn. The present study investigates the behaviour of a silicone component of a manufacturing equipment and the variations in the part’s properties due to in-service conditions (temperature, exposure to heat transfer fluid, and mechanical deformation) to develop a monitoring tool. An experimental design was employed to study the main and the interaction effects of temperature (22 °C, 180 °C), medium (air, synthetic heat transfer fluid), and strain (0%, 200%) on the silicone component’s properties. Results showed that while the chemistry of the component remains intact, its thermal and in particular mechanical properties are largely influenced by the in-service conditions. Consequently, leading to a physical rather than a chemical failure of the component and limiting its service life. Statistical analysis revealed that high temperature and the exposure to the heat transfer fluid have the most sever effects. Moreover, these two manufacturing parameters were found to have a significant interaction with one another, whose effect cannot not be neglected.
