“…Hybrid-conducting particles and fibers were employed to make the arrays electrically conductive for the self-sensing test. The surface area of the graphite (G) was 10-35 (m 2 /g), the Particle size was 40-150 μm, and the bulk density (g/cm 3 ) was 1.9-2.3 (Figure 1-b) [8,9]. As a small-scale electrical conductor, 12 mm chopped carbon fiber (CF) with aspect ratios of 1600 was employed (Figure 1-a).…”

“…[ 27‐28 ] Analogously, carbon‐based nanomaterials have also gained attentions. Carbon black (0D), [ 29 ] carbon nanotubes (CNTs) (1D), [ 30‐31 ] and graphene (2D) [ 32‐35 ] are considered promising conductive fillers due to the outstanding electrical conductivity, superior chemical stability, and facile functionalization. In certain cases, the hybrids of metal‐based and carbon‐based nanomaterials could result in a synergistic effect.…”

Comprehensive Summary With the rapid growth of soft electronic and ionotronic devices such as artificial tissues, soft luminescent devices, soft robotics, and human‐machine interfaces, there is a demanding need to accelerate the development of soft ionic conductive materials. To date, the first‐generation ionotronic devices are mainly based on hydrogels or ionogels. However, due to their intrinsic drawbacks, such as freezing or volatilization at extreme temperatures, and the leakage problem under external mechanical forces, the reliability of ionotronic devices under harsh conditions remains a great challenge. The advent of liquid‐free ionic conductive elastomers (ICEs) has the potentials to solve the issues related to the gel‐type soft conductive materials. The free ions shuttling within the ion‐dissolvable polymer network enable liquid‐free ICEs to exhibit unparalleled ionic conductivity and elasticity. Moreover, by tuning the composition and structure of the polymeric network, it is also feasible to integrate other desirable properties, such as self‐healing ability, transparency, biocompatibility, and stimulus responsiveness, into liquid‐free ICE materials. In this review, we summarize the design strategies of recently reported liquid‐free ICEs, and further explore the methods to introduce multifunctionality, which originate from the rational molecular design and/or the synergy with other materials. Moreover, we highlight the representative applications of liquid‐free ICEs in soft ionotronics. It is believed that liquid‐free ICEs might provide a unique material platform for the next‐generation ionotronics.

“…Unlike previous research, this study investigated the utilization of hollow glass microspheres, cenosphere, and graphite flakes in the cement mortar to improve the damping ratio while trying to avoid the drawbacks of other materials as mentioned above. Although previous studies applied hollow glass microspheres (HGM) and cenospheres (CS) to develop lightweight concrete [ 20 , 21 , 22 ], and graphite flakes (GF) were used for controlling the conductivity of concrete [ 23 ], there is no existing study focusing on evaluating the damping ratio of mortar that contained these materials. Compared with rubber particles (RP), RA, and fibers, HGM has several advantages, such as high thermal resistance, reducing shrinkage, and improving the workability of mortar [ 24 ].…”

The vibration-reducing ability of construction materials is generally described by the damping ratio of the materials. Previously, many studies on the damping ratio of concrete have been done, such as the addition of rubber, polymer, fiber, and recycled aggregates in the concrete. However, the application of these materials in construction is limited due to their drawbacks. This paper investigated the effect of the replacement ratio and the size of the hollow glass microspheres (HGM), cenospheres (CS), and graphite flakes (GF) on the damping ratio of mortar. Furthermore, rubber particles (RP), aluminum powder (AP), and natural fiber (NF) were investigated to find if they have a combination effect with HGM. The half-power bandwidth method was conducted to obtain the damping ratio at 28 days of curing, and the compressive and flexural strength tests were also conducted to study the mechanical properties of mortar that contained HGM, CS, and GF. The results show that increases in the size of HGM and the replacement ratio of sand with HGM lead to an increase in the damping ratio. Moreover, RP and NF do not provide a combination effect with HGM on the damping ratio, whereas the application of AP results in a drastic compressive strength decrease even with an increase in damping ratio when incorporated with HGM. Besides, an increase in the replacement percentage of CS also leads to an improvement in the damping ratio, and a smaller size and higher replacement ratio of GFs can improve the damping ratio compared to other additives. As a result, CS and GF are more effective than HGM. 50% replacement ratio of CS slightly reduced the compressive strength by 6.4 MPa while improving the damping ratio by 15%, and 10% replacement ratio of samller GF can enhance the flexural strength by over 4.55% while increasing the damping ratio by 20.83%.
