“…Stretchability also increases with the increasing amount of BT and is the maximum when filler loading is 8 phr. Further increase in the filler content decreases the stretchability because of agglomeration of fillers, that is, optimum limit of crosslink density, see Yang et al 36 The variations of elastic modulus of the NR/BT composite with filler content are shown in Figure 6(b). It is observed that the elastic modulus increases with increase in filler content from 2 to 5 phr.…”

“…The addition of CNT increases the dielectric constant of the composite but the dielectric breakdown decreases. 47,48 Yang et al 36 added titanium-oxide (TiO 2 ) in natural rubber and conducted electrical and mechanical characterizations of the fabricated composites. They reported increases in dielectric constant from 3.14 to 3.56 with the change in BT filler content of 50 phr.…”

Natural rubber is one of the most potential electro‐active polymers for sensors, actuators, and energy harvesting applications. Enhancing the characteristic properties of polymers by reinforcing with fillers that possess multifunctional attributes have attracted considerable attention. In the present study, barium titanate reinforced natural rubber composite is prepared by using two‐roll mill mixing. Afterwards, mechanical, electrical, and electromechanical properties of the composites are extensively analyzed by reinforcing different amounts of barium titanate into the matrix of natural rubber. The fabricated dielectric composite shows excellent properties such as high dielectric constant, low dielectric losses, high dielectric breakdown strength, and extreme stretchability. It is observed that as the filler loading reaches the value of 11 parts per hundred rubber (phr), maximum agglomeration of the particles occurs. Maximum stretchability and highest ratio of dielectric constant to elastic modulus are obtained at 8 phr of barium titanate fillers and at the loading, a maximum actuation strain of 11.24% is achieved. This study provides a simple, economical, and effective method for preparing enhanced mechanical, electrical, and electromechanical properties of natural rubber composites, facilitating the wide applications of dielectric materials as actuators and generators.

“…This nding can be attributed to the agglomeration of Gh-BN in the polymer matrix, where the organic functional groups present on h-BN enhance the possibilities of polarization and moisture absorption. 47 The decrease is largely dependent on the EPPOSS modication with a nano-porous structure because porosity will always lead to a lower dielectric constant as air has the lowest dielectric constant among all materials. [48][49][50] Moreover, PI/EPPOSS@Gh-BN shows the lowest measured values of electrical conductivities and dielectric losses in the range of 10 MHz, as shown in Fig.…”

“…Furthermore a new peak appears at 1687 cm À 1 , which corresponds to the C=N bending vibration in the aromatic ring, indicating that PCPA was successfully prepared by auto-polymerization. [36,37] In order to further ensure this conclusion, energy dispersive spectrometer (EDS) analysis is performed on the membrane. As shown in Figure 3B, except for Si, C, and O uniformly distributed on the PE@SiO 2 -PCPA layer, the element N is uniformly distributed over the entire PE@SiO 2 -PCPA membrane, thereby demonstrating that PCPA coating has successfully adhered to the surface of the ceramic membrane.…”

A composite membrane based on SiO 2 and a low-cost poly (catechol/polyamine) (PCPA) multicomponent system was prepared by using a simple dip-coating processes. The results indicate that the formation of an inorganic/organic composite coating on the surface of the polyethylene (PE) separator is beneficial for improving the comprehensive performance, especially for the thermal stability and wettability. Compared to the PE separator, the thermal stability of the PE@SiO 2 -PCPA composite membrane is greatly improved, showing a higher decomposition temperature (426°C) and a smaller heat shrinkage rate at 160°C. Moreover, the Li/LiCoO 2 battery assembled with the PE@SiO 2 -PCPA composite membrane shows an excellent initial discharge capacity and a remarkable capacity retention (171.5 mAh g À 1 , 86.1 %) at 4.4 V after 200 cycles at 0.5 C, which much higher than the PE membrane (165.2 mAh g À 1 , 61.4 %). This study provides a potential application for membranes with low cost, high thermal stability, and good wettability in the field of lithium-ion batteries.
