“…The SRs adding with smaller particle size additives are expected to have a longer service life than the SR adding with larger particle size additives, which may associated with higher surface roughness and poor thermal conductivity in larger particle size additives. Precipitated silica and fumed silica are generally used as reinforcing fillers for two‐component condensation‐type room temperature vulcanized SR (RTV‐SR), which can significantly improve the mechanical properties and thermal stability of SR composites (Mishra et al., 2022; Wang et al., 2021; Zhao & Zhang, 2015). RTV‐SR filled with nano‐silica had higher corrosion resistance than RTV‐SR filled with micro‐silica (Meyer et al., 2006).…”

Silicone rubber (SR) is widely used in the food processing industry due to its excellent physical and chemical properties. However, due to the differences in SR product production formulas and processes, the quality of commercially available SR products varies greatly, with chemical and biological hazard potentials.Residual chemicals in SR, such as siloxane oligomers and 2,4-dichlorobenzoic acid, are non-intentionally added substances, which may migrate into food during processing so the safe use of SR must be guaranteed. Simultaneously, SR in contact with food is susceptible to pathogenic bacteria growing and biofilm formation, like Cronobacter sakazakii, Staphylococcus aureus, Salmonella enteritidis, and Listeria monocytogenes, posing a food safety risk. Under severe usage scenarios such as high-temperature, high-pressure, microwave, and freezing environments with long-term use, SR products are more prone to aging, and their degradation products may pose potential food safety hazards. Based on the goal of ensuring food quality and safety to the greatest extent possible, this review suggests that enterprises need to prepare high-quality food-contact SR products by optimizing the manufacturing formula and production process, and developing products with antibacterial and antiaging properties. The government departments should establish quality standards for food-contact SR products and conduct effective supervision. Besides, the reusable SR products should be cleaned by consumers immediately after use, and the deteriorated products should be replaced as soon as possible.

“…Therefore, this shift imposes greater demands on the thermal conductivity capabilities of thermal interface materials (TIMs) [3][4][5][6]. Silicone rubber (SIR) is widely selected as the matrix material for TIMs due to its wide viscosity range, adjustable hardness, high insulation, good filler compatibility, and excellent reliability [7][8][9]. Compared with polyurethane, acrylic acid, and epoxy resin, SIR has better filling ability and reliability with respect to thermally conductive particles.…”

In the realm of thermal interface materials (TIMs), high thermal conductivity and low density are key for effective thermal management and are particularly vital due to the growing compactness and lightweight nature of electronic devices. Efficient directional arrangement is a key control strategy to significantly improve thermal conductivity and comprehensive properties of thermal interface materials. In the present work, drawing inspiration from natural leaf and branch structures, a simple-to-implement approach for fabricating oriented thermal conductivity composites is introduced. Utilizing carbon fibers (CFs), known for their ultra-high thermal conductivity, as branches, this design ensures robust thermal conduction channels. Concurrently, boron nitride (BN) platelets, characterized by their substantial in-plane thermal conductivity, act as leaves. These components not only support the branches but also serve as junctions in the thermal conduction network. Remarkably, the composite achieves a thermal conductivity of 11.08 W/(m·K) with just an 11.1 wt% CF content and a 1.86 g/cm3 density. This study expands the methodologies for achieving highly oriented configurations of fibrous and flake materials, which provides a new design idea for preparing high-thermal conductivity and low-density thermal interface materials.

“…Silicone rubber foam (SRF) integrates the characteristics of both silicone rubbers and foam materials. SRF exhibits excellent performances, such as being lightweight, having superior temperature resistance, having a low compression set, and having good compression resilience [1][2][3][4]. Therefore, SRF has a multitude of uses in many fields such as the automobile industry, the aerospace field, electronics, and healthcare [5,6].…”

Chemical foaming technology is widely used in the preparation of silicone rubber foam and is attributable to its one-step molding capability and eco-friendly production processes. The microrheological properties of silicone rubber play a pivotal role during the foaming process. In this study, Rheolaser Lab (Formulaction, Toulouse, France) was used to conduct in situ examinations for the influence of a crosslinking agent on the microrheological properties of silicone rubber foam for the first time. This study monitors the entire reaction process of silicone rubber foam from liquid to solid, as well as the matching of crosslinking and foaming reactions. Various parameters, including solid–liquid balance, elasticity index, and macroscopic viscosity index, are measured to analyze the microrheological properties of silicone rubber foam. The results show that the silicone rubber foam exhibits good microrheological properties, thereby demonstrating excellent performance at a crosslinking agent content of 2%. Through adjusting the experimental conditions, a sustainable and efficient approach was proposed for better cellular structure control in the industrial preparation of silicone rubber foam.
