Low-dimensional carbon materials have been widely used to enhance the properties of polymer composites. However, low-dimensional are easy agglomerate in matrix due their nanoscale effects. It may be a good choice use coordination effect between nanomaterials different dimensions dispersion fillers and performance In this paper, two-dimensional Ti3C2Tx MXene one-dimensional nanotubes (CNT) was prepare methyl vinyl silicone rubber (VMQ) composites with enhanced properties. The research shows that appropriate proportion CNT can improve VMQ optimize conduction path, leading interfacial polarization micro-capacitor effect, thus improved dielectric property Dielectric constant 7.85 (2.7 times pure VMQ) obtained composites, while loss tangent 0.00122 at 1 kHz. addition, mechanical were also improved, Young's modulus value lower than 500 kPa. prepared by adding nano-fillers display properties, which has certain guiding significance for high

Fluorosilicone rubber is essential for sealing in extreme temperatures and non-polar environments due to its exceptional adaptability. However, achieving a high yield of fluorosilicone polymers with medium fluorine content remains challenge. Herein, facile gradient strategy developed that involves modifying the method cyclic monomer addition based on rate ring-opening polymerization (ROP), improve adjust precisely. The process designed tailored reaction rates anionic (AROP) cationic (CROP) via an efficient strategy. effects viscosity vinyl hydrofluorosilicone are investigated optimized. Notably, as-prepared vinyl-terminated fluoromethylsilane 60% (FMS-Vi-60F) has (86.6%) (150 000 mPa·s) short time, which superior previous methods. Clearly, this work provides synthesis fabricating tunable content.
