“…The findings show that the CB has a mitigating effect on oil-induced deterioration in LSR. However, as the CB content increased, the swelling ratio decreased, and it was observed that the swelling ratio increased slightly when 3 wt% of CB was added, which is presumed to be due to the agglomeration of the CB [38,39]. Furthermore, it was verified that the variation in swelling rate, dependent on the CB content, becomes more pronounced at elevated temperatures compared to room temperature.…”

“…This accounts for the slight increase in the swelling ratio observed in the CB content of 3 wt%, as mentioned in Section 3.2. Consequently, in the CB/LSR tensile test shown in Figure 4b, the tensile strength increased with the rising CB content but experienced a slight decrease at 3 wt%, which was attributed to the observed agglomeration [38,39]. pared to the specimens with CB content of 1 wt% and 2 wt%, and some agglomeration was also observed.…”

Liquid silicone rubber (LSR) garners attention across a diverse range of industries owing to its commendable fluidity and heat resistance. Nonetheless, its mechanical strength and oil resistance fall short compared to other rubbers, necessitating enhancement through the incorporation of a suitable filler. This research focuses on reinforcing LSR using carbon black (CB) particles as a filler, evaluating the mechanical properties and oil resistance of neat LSR, and LSR containing up to 3 wt% of CB filler. CB was added in powder form to investigate its effect on LSR. When LSR was impregnated with oil, the deterioration of rubber was noticeably observed under high-temperature conditions compared to room-temperature conditions. Consequently, the mechanical properties and oil resistance, excluding the permanent compression reduction rate, tended to increase as the filling content of CB increased compared to the unfilled state. Notably, in the specimen with 2 wt% CB filler, the tensile modulus increased significantly by 48% and the deterioration rate was reduced by about 50% under accelerated deterioration conditions. Additionally, the swelling rate in oil decreased by around 14%. This validates a notable improvement in both mechanical properties and oil resistance. Based on the identified mechanism for properties enhancement in this study, CB/LSR composite is expected to have a wide range of applications in fields such as gaskets, oil seals, and flexible sensors.

“…The use of various fillers in SR has gained significant attention for their ability to enhance the composite's desired properties 17 . Different fillers, such as carbon black, 18 silica, and metal oxides, 19 offer distinct advantages depending on the desired characteristics of the final product. Carbon black, a commonly used filler, enhances the properties of SR by improving tensile strength, tear resistance, and abrasion resistance 20 .…”

Adding graphite nanoplatelets (GNP) into silicone rubber (SR) composites have shown significant potential for wearable electronics, where electrical, mechanical, and tribological properties play a crucial role. This study investigates the effects of incorporating graphite nanoplatelets (GNP) into SR composites and their impact on these key properties. Solution mixing of SR and GNP was performed to confirm good dispersion of the GNP within the SR matrix. The results showed improved tensile strength and modulus while stabilizing the flexibility and stretchability required for wearable electronics. For example, the tensile strength of the composites was 0.86 MPa (control) and increased to 1.18 MPa (5 part per hundred rubber [phr] GNP), and 1.55 MPa (15 phr GNP). Similarly, the stretchability was 177 % (control) and increased to 190 % (5 phr GNP), and 184 % (15 phr GNP). Moreover, the electro‐mechanical tests were studied and the output voltage for the samples were 0.28 milli‐volt (mV) (5 phr GNP), and 0.31 mV (15 phr GNP). Similarly, the output voltage generation was studied through human motions. The results obtained from these biomechanical motions such as thumb pressing were 0.7 mV (5 phr GNP), and 2.7 mV (15 phr GNP). The study finds the potential of GNP‐SR composites as multifunctional materials such as wearable electronics. Overall, this research guides the development of advanced wearable devices, soft robotics, and bio‐inspired electronics with improved performance and durability.

“…This typically involves adding more fillers to establish a continuous conductive network within the polymer, a crucial step for achieving optimal electrical conductivity. [31][32][33][34][35][36] However, a major obstacle lies in attaining uniform dispersion when blending conductive fillers directly into polymer substrates through physical blending, thereby restricting the practicality of this approach. 37 In order to enhance the dispersibility of conductive fillers in a polymer matrix, the functionalization method is commonly employed.…”
