Summary: A novel silicone rubber (C-RTV/WMMQ) was successfully fabricated by adding white carbon black and different percentages of methyl MQ silicone resin to C-RTV silicone mold rubbers, which showed improved mechanical properties and thermal stability. Experimental results demonstrated a feasible synergistic effect and compatibility mechanism, resulting in a dense crosslinking network structure in the polymer matrix.

Summary: Recent advances in additive manufacturing, such as DIW and ink-jetting, have allowed for deterministic control over the structure, shape, and mechanical properties of elastomeric silicone parts. While SLA technology offers finer features, the high viscosity of silicone resins complicates the layer-by-layer recoating process, necessitating the development of new approaches like the digital light projection SLA printer demonstrated in this study.

Summary: In this work, different lengths of hydroxyl silicone oil chains modified boron nitride/silicone rubber composites were explored and prepared, and it was found that the long-chain modified composites improved thermal conductivity and decreased dielectric loss. Molecular dynamics simulation revealed that the interfacial behavior played a key role in improving thermal and dielectric properties. Results showed that the longer-chain modified composites had better thermal and dielectric properties. This research provides a theoretical foundation for the development of materials with designable performance for electronic devices.

Summary: High ablation-resistant silicone rubber composites with nanoscale dispersed phenolic resin particles were synthesized and demonstrated improved mechanical strength and enhanced char yield. Compared with conventional silicone rubber, these composites showed significant reductions in linear and mass ablation rates. The introduction of dynamic urethane bonds and enhanced structural compatibility played crucial roles in achieving these improvements.

Summary: The composite insulation material composed of XLPE and SiR is commonly used in high voltage direct current cable accessory installation. However, the accumulation of space charge, especially at the interface of XLPE/SiR, poses a serious threat to the safe operation of cable accessories, and its charge transport mechanism is still unclear, especially at the micro-scale. This study investigates the charge transport mechanism of XLPE/SiR by simultaneously measuring space charge and relaxation current at various electric fields with different polarities. Quantum chemical calculation is used to determine the electronic energy levels of XLPE and SiR. The results show significant differences in interfacial charge accumulation and composite conductivity of XLPE/SiR under different polarities, suggesting an obvious polarity effect.

Summary: UV/moisture dual curable siloxymethyl-modified silicone acrylate (SMSA) prepolymers were synthesized via sequential hydrosilylation of pentaerythritol tetraacrylate (PETTA), hydride-terminated polydimethylsiloxane (H-PDMS), and trimethoxysilane (TMOS). These prepolymers combine the advantages of UV and moisture curing, allowing for rapid curing and addressing the issues of UV curing in shadowed areas and thick coatings. The dual curing process also resolves the problems of oxygen inhibition and poor adhesion commonly associated with conventional UV-curable silicone materials. The UV/moisture dual cured coatings have potential applications in UV-curable anti-smudge and anti-fingerprint coatings.

Summary: In this study, the flame retardant properties of silicone rubber foam (SRF) composites were improved by using modified hydrotalcites (LDHs) with different Ce/Al molar ratios. The addition of LDHs resulted in a significant reduction in heat release rate, smoke production rate, and total smoke production, as well as an increase in thermal stability of the SRF composite. These findings provide guidance for the development of environmentally friendly SRF.

Summary: Compared with HTVSR insulator, alicyclic epoxy resin insulator has higher hardness and better bonding between the core and the sheath. Alicyclic epoxy resin insulators are significantly influenced by UV-A radiation, resulting in noticeable changes in appearance and a certain degree of fading. Mechanical properties are well maintained while hydrophobicity decreases gradually. In contrast, silicone rubber insulators experience smaller changes in appearance, significant decrease in mechanical properties, and gradual reduction in hydrophobicity. Both materials meet the requirements for outdoor operation.

Summary: The addition of diphenylsilanediol to epoxy resin as a modifier improves the hygrothermal aging resistance and dielectric properties of silicone-modified insulation materials. The presence of diphenylsilanediol reduces the size of cracks in the material during hygrothermal aging, leading to better overall performance. However, excessive silicone material in the epoxy resin may result in poorer dielectric properties.

Summary: Transparent and easily fabricated films were successfully obtained by coupling eugenol and poly(methylhydrosiloxane), with high thermal stability and optical properties. Increasing eugenol content improved the thermal stability and refractive index of the films, making them suitable for optical encapsulants and high-refractive index LED encapsulants. Additionally, the films also exhibited good water vapour barrier properties and water repellence for protecting encapsulated chips from moisture erosion.
