“…In most cases, the tensile strength presents a sharp increase at low strain, thus making it not suitable for application in DEAs 234 . It was shown by Molberg et al that packing of PANI particles by the shell of insulating polymer before their dispersion in PDMS oligomer enhanced the compatibility of PANI/PDMS along with an increase in the breakdown of the strength of the system; thus, filler agglomeration decreases while dielectric loss increases 235, 236 . From this approach, composite of improved dielectric properties was prepared compared to pure PDMS while their dielectric nature was maintained.…”

In recent 20 years, electronic equipment has been developing rapidly in the direction of light, miniaturization, flexibility, and integration. It is urgent to meet the needs of matching energy supply system to solve the practical application requirements in the fields of intelligent communication and mobile medical treatment. Electroactive polymers (EAPs) are recommendable material for manifesting muscle-like actuation. The dielectric elastomers (DEs) obtained from the EAPs are quite capable of inducing electrical energy and transmute it into mechanical energy. DEs are capacitors covered by an outer elastic membrane, sandwiched between the two docile electrodes. In the beginning, for getting the efficient responses out of the DE actuators, the material requirements and electromechanical principal are applied. Viscoelastic damping, low dielectric loss, stretch ability, and dielectric permittivity are the desirable characteristics that we are expecting in a polymer. In the current research, we are going to adopt the sequential approach by describing the advances, challenges, and applications of DEAs in the coming future.

“…The binding energies at peak positions of 529.4, 531.3, and 532.9 eV in Figure S4a correspond to lattice oxygen (Mn–O–Mn), Mn–O–H, and H–O–H, accordingly. 51 , 52 At 182.5 and 184.7 eV, the Zr 3d 3/2 and Zr 3d 5/2 were obtained, respectively ( Figure S4b ). Zr binding energy in catalysts was larger than that of pure metal at 180.0 eV, lower than that of ZrO 2 at 182.9 eV, and comparable to that of ZrOx at 181.4 eV, 53 indicating successful integration of Zr cations.…”

Cellulose nanocrystals (CNC), MnO 2 , CNC-doped MnO 2 , and Zr/CNC-doped MnO 2 were prepared with a hydrothermal method to assess their photocatalytic and antibacterial properties. Various characterizations were undertaken to determine the phase composition, the existence of functional units, optical characteristics, elemental analysis, surface topography, and microstructure of the prepared materials. Sample crystallinity was improved, whereas a decrease in crystallite size was observed with increasing amounts of dopants. Incorporation of dopants (CNC and Zr) into MnO 2 instigated a transformation in morphology from nanoclusters to nanorods with different diameters. Furthermore, photocatalytic activity experiments indicated a more effective degradation of methylene blue (MB) dye with CNC-doped MnO 2 and Zr/CNC-codoped MnO 2 while enhancing the bacterial efficacy for both G +ve and G −ve. Density functional theory was utilized to model the structures and elucidate their bonding and charge transfer mechanisms. The Zr/CNC-MnO 2 system showed charge depletion around Mn atoms, while charges were observed to accumulate around oxygen atoms.

“…The DND particles were treated for purification by heating at 440 °C in a furnace and then functionalized with amine groups using a ball-milling method. 19 Our previous work shows that DND particles have high surface energy caused by high surface to volume ratio and small particles size responsible for high agglomeration. 34 In order to decrease agglomeration, amine groups were attached on the DND surface which plays an important role in de-agglomerations of the DND particles.…”

Titanium oxide (TO)-and functionalized nanodiamond (FND)-reinforced carbon foam (CF) composites were prepared by the direct pyrolysis of TO, FND and a mixture of mesophase coal tar pitch. The effects of TO and FND loadings on the microstructure and functional properties of the CF composites were studied. The obtained microstructures of the CF composites showed that both nanofillers have an influential role in the formation of porous morphology of CF. Moreover, the additive aspects of TO and FND were further studied in terms of mechanical, thermal and electrical properties. The results revealed that compressive strength increased up to 20.21 MPa, thermal conductivity was as high as 32.33 W m −1 K −1 at elevated temperature and electrical conductivity was 23.24 × 10 3 S m −1 . The results show that FND particles are well appropriate to meliorate the fabrication of TO nanoparticles in CF to build up a solid connection between the nanoparticles and CF for the improvement of the mechanical, thermal and electrical properties of CF composites.
