However, it is still a challenge to obtain fibrous DEs possessing high electric field induced deformations. In this work, the fabrication of high dielectric lanthanum-doped barium titanate (La-BTO) encapsulated multiwall carbon nanotubes (MWCNTs) (La-BTO@MWCNTs) incorporated in styrene-ethylene-butylene-styrene copolymer (SEBS) is described. The outcome of this process is a DE with excellent electromechanical performance. The results obtained from testing demonstrated that La doping effectively enhanced the dielectric constant of La-BTO@MWCNTs. A high dielectric constant of 2.77 was achieved for a low amount of La doping (the molar ratio of Ba:La was 100:1). The DE actuator (DEA) containing 2.0 % La-BTO@MWCNTs exhibited a maximum actuated longitudinal strain of 23.12 % and a maximum output force of 25.85 mN for an electric field of 50 V/μm. Furthermore, the SEBS/La-BTO@MWCNTs based DEA provided reliable working stability over 100 voltage cycles from 0 to 5 kV.

In this study, polypropylene (PP)-based TPNCs were fabricated using different grades of graphitic carbon nanoparticles (CNPs) to yield electrical conductivity and electromagnetic interference shielding effectiveness (EMI SE). The applied structuring methodology consists of a multiscale processing strategy that combines high-energy ball milling of polymer micro-pellets and CNPs, formulated powder compaction into green bodies, and EM-driven localized heating to produce the TPNCs. This enables the formation of highly segregated, percolated conductive networks at ultra-low filler loadings. The percolation threshold values for green bodies were significantly dependent on CNP morphology, ranging from approximately 0.50 wt% for low-aspect-ratio graphene nanoplatelets to around 1.0 wt% for medium-aspect-ratio carbon nanotubes (CNTs). Upon EM melt-processing, due to viscoelastic deformation of CNP networks, the resulting threshold values of the structured TPNCs were approximately 0.73 wt%, 0.50 wt%, and 0.74 wt% for low, medium, and high aspect ratios, respectively. High-aspect-ratio CNTs, despite exhibiting greater structural defects, achieved the highest EMI SE of 19.7 dB/mm at 10 wt%, demonstrating that morphology dominates over graphitic crystallinity in governing transport properties and electromagnetic performance.

This research examines the influence of interlayer TiC particle incorporation (0.2–0.8 wt%) on the microstructural evolution and tribological behavior of wire arc additively manufactured Al-5Mg alloys. Results demonstrate that TiC particles significantly refine grain size and reduce anisotropy of Al-5Mg alloys.

The coefficient of friction (COF) and wear rate exhibit a marked decline across varying applied loads. This enhancement is primarily originated from TiC's inherent hardness and strong interfacial bonding with the Al matrix, enabling effective load transfer during friction. However, TiC pseudo-dispersion degrades the wear performance when TiC content exceeds 0.6 wt%.
