“…SM is superior to that of composites prepared by MM, which is consistent with the results of some researchers [38][39][40]. SM helps BN to physically adhere to the surface of UHMWPE particles, and composite materials with isolated structure can be prepared by molding, which results in improvement of thermal conductivity of UHMWPE/BN composites.…”

UHMWPE/BN composites were prepared by solvent mixing (SM) in this work, then were characterized by scanning electron microscope (SEM), Raman mapping, differential scanning calorimeter (DSC), thermogravimetric analysis (TG), and thermal conductivity meter to study the morphology, filler distribution, segregated structure, and thermal stability as well as thermal conductivity. Compared to the traditional melt mixing (MM), SM followed by molding contributes to the construction of segregated structures in UHMWPE composite. This segregated structure can greatly improve the thermal conductivity of the composites. The segregated structure of composites prepared by MM is destroyed by shearing. Moreover, the thermal stability of composites by SM is improved with the increment of BN content, which is better than that of samples by MM, probably resulting from the barrier function of the segregated structure.

“…Nevertheless, both the contraction rate and the stroke recovery rate are faster for the sheath-driven muscle than for the hybrid muscle, since only the muscle sheath contains high thermal conductivity CNTs. [35,36]…”

Electrothermal carbon nanotube (CNT) yarn muscles can provide large strokes during thermal cycling. However, the slow cooling rate of thermal muscles limits their applications, since large diameter prior-art thermal muscles cannot be rapidly cycled. Herein, a fast thermally powered sheath-driven yarn muscle that uses a hybrid CNT sheath and an inexpensive polymer core, is reported. The stroke recovery rate for the hybrid muscle is much lower at all frequencies than for about the same diameter sheath-driven muscle, which means that the full cycle contractile mechanical power is much higher than for comparable prior-art hybrid muscle. More specifically, the coiled sheathdriven muscle contracts 14.3% at 1 Hz and 7.3% at 8 Hz in air when powered by a square-wave electrical voltage input, which is 2.9-and 11.4-times the stroke of the coiled hybrid muscle at these respective frequencies. An average power density of 12 kW kg −1 is obtained for a sheath-driven muscle, which is 42-times that for human skeletal muscle. These high-performance results since the heating that drives fast actuation cycles are largely restricted to the muscle sheath, and this sheath is in direct contact with ambient temperature air.

“…Today, changes in technology have affected the production of whole metallic filaments. There has been a paradigm shift from the manufacture of whole metallic yarns to the production of blended spun yarns (spinning metallic fibers and staple fibers or filaments), [19][20][21] preparation of conductive composite materials, [22][23][24] coating conventional natural and synthetic fibers and yarns with conductive materials, 25,26 novel nano-materials, 27,28 and development of new non-metallic inherently conductive materials. 29,30 Fig.…”

Electrical Conductivity in Textile Fibers and Yarns—Review

View full text Add to dashboard Cite

This paper presents an extensive review on electrical conductivity in textile fibers and yarns. The focus is an attempt at exhaustively classifying various types of conductive yarns based on their modes of manufacture, composition, and areas of application. Yarn classes include whole metallic yarns, composite conductive yarns, plated yarns, conductive polymer yarns and yarns made of new nano-materials and nano-composites. Electrical conductivity is exploited to effect smart textile applications such as strain sensing, capacitance, antimicrobial activity, antistatic and electromagnetic shielding. The lack of clear distinction in conductive yarn categorization and their possible areas of application are clarified in this review.
