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

Vascular tissue engineering technology uses tubular viscoelastic materials as intermediaries to transmit the mechanical stimuli required for construction of vascular grafts. However, most existing studies rely on elastic models, which fail capture time-dependent nature materials. Moreover, long fabrication cycles, high costs, and complex parameter measurements in pose significant challenges experimental approaches. There is thus an urgent need develop a model that combines physical interpretability, computational efficiency, predictive accuracy, enabling precise characterization material responses unified quantification across platforms. Here, we propose error-corrected linear solid (ECLS) with embedded correction term address deviations conventional models nonlinear scenarios. Instead expanding traditional structure, ECLS incorporates error method improves performance while maintaining structural simplicity. Experiments were conducted three representative materials-silicone rubber, polyurethane, polytetrafluoroethylene-to acquire time-resolved response data through stress relaxation creep tests. The fitting was quantitatively evaluated using Euclidean norm Akaike information criterion, systematic comparison between classical (Kelvin-Voigt, Maxwell, standard [SLS]). results show exhibits higher accuracy over wide time range, average goodness fit (R2) 0.99, representing improvement ∼6% compared SLS model. Furthermore, Root Mean Square Error (RMSE) Absolute (MAE) are at least one order magnitude lower than those significantly improving description behavior providing more accurate predictions behavior. Therefore, not only modeling but also establishes scalable framework predicting optimizing tissue-engineered vessels, application potential bioreactor design biomaterials development.

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.
