Conductive polymer composites use elastomers as a matrix for strain sensors. However, elastic polymer composites usually exhibit shoulder peak effects in their resistance response signals, limiting their applicability as strain sensors. In this study, we modified multiwalled carbon nanotubes (MWCNTs)/methyl vinyl silicone rubber (VMQ) by incorporating nanosilica (NSD) to eliminate the shoulder peak effect. The results showed that the addition of a suitable amount of NSD can improve the reconstruction of the conductive network of composite material and eliminated the shoulder peak effect of the composite material in the resistive response signal. The mechanism of eliminating the shoulder peak effect was elucidated, while the mechanical properties of the composite material were improved, which endowed the composite material with excellent strain sensing properties, including sensitivity (GF = 127) and response time (270 ms), and maintained excellent stability and recovery even in 15,000 cycles. These findings highlight the potential of our strain sensor for the real‐time strain monitoring of large‐deformation isolation bearings.Highlights NSD eliminates shoulder peak effect in MWCNT/VMQ composites. Explained the shoulder peak effect elimination mechanism. NSD enhanced mechanical properties of MWCNT/VMQ composites. MWCNT‐NSD20/VMQ composites have stable resistive strain response properties.

In order to realize effective monitoring for the working performance of seismic isolation structures, a multi-walled carbon nanotube (MWCNT)/methyl vinyl silicone rubber (VMQ) composite was prepared via mechanical blending using dicumyl peroxide (DCP) and 2,5-dimethyl-2,5-di(tert-butyl peroxy)hexane (DBPMH) as vulcanizing agents. The effects of the different vulcanizing agents on the dispersion of the MWCNT, electrical conductivity, mechanical properties, and resistance–strain response of the composites were investigated. The experimental results showed that the percolation threshold of the composites prepared with the two vulcanizing agents was low, while the DCP-vulcanized composites showed high mechanical properties and a better resistance–strain response sensitivity and stability, especially after 15,000 loading cycles. According to the analysis using scanning electron microscopy and Fourier infrared spectroscopy, it was found that the DCP contributed higher vulcanization activity, a denser cross-linking network, better and uniform dispersion, and a more stable damage–reconstruction mechanism for the MWCNT network during the deformation load. Thus, the DCP-vulcanized composites showed better mechanical performance and electrical response abilities. When employing an analytical model based on the tunnel effect theory, the mechanism of the resistance–strain response was explained, and the potential of this composite for real-time strain monitoring for large deformation structures was confirmed.

In this paper, we experimented to determine the ideal ratio of magnetic properties/PLA composites for creating magnetic filaments for FDM 3D printing. To achieve this, we created 15 samples using the control variates method, analyzing factors such as the type of material used, the powder size of the magnetic substance, and PLA pellet size. Also, Our approach utilized a novel method of combining the sol-gel and co-blending methods to produce uniform and high-induced magnetic field strength properties in the magnetic substance/PLA binary composites. By comparing Maximum tesla measurement results, we determined that using NdFeB is preferable to Fe3O4 in our particular conditions. We found that the composites’ magnetic properties depend only on the materials and mass ratio of the magnetic substance, with the ideal ratio being 2: (4-6): 8 for binders, magnetic substances, and PLA, respectively. Finally, based on our findings, we produced a sample filament and suggested possible applications.
