“…A similar effect was achieved with a coating of porous PPy spheres (Li et al 2019g). To prevent polysulfide diffusion an additional interlayer of carbon fibers coated with PPy has been proposed (Li et al 2019h). Beyond physical adsorption of polysulfide the interlayer also reduced electrode polarization of the sulfur electrode.…”

Intrinsically conducting polymers and their copolymers and composites with redox-active organic molecules prepared by chemical as well as electrochemical polymerization may yield active masses without additional binder and conducting agents for secondary battery electrodes possibly utilizing the advantageous properties of both constituents are discussed. Beyond these possibilities these polymers have found many applications and functions for various further purposes in secondary batteries, as binders, as protective coatings limiting active material corrosion, unwanted dissolution of active mass ingredients or migration of electrode reaction participants. Selected highlights from this rapidly developing and very diverse field are presented. Possible developments and future directions are outlined.

“…It leads to the result that movement of the polymer molecular chain is severely restricted, and the energy required to overcome the internal friction between the segments during the segment movement is reduced, thus reducing the viscoelastic energy needed for the composite material in the glass transition zone is obtained. Because the movement of the molecular chain is limited, and a higher temperature is required, the glass transition temperature is increased [ 35 ] …”

This research uses physical mixing and twin‐screw extrusion process to prepare biomass activated carbon (BAC)/ultra‐high molecular weight polyethylene (UHMWPE) composite materials. The mechanical properties, micro‐morphology, and thermodynamic properties of the composite materials were explored. The experimental results show that the tensile strength of 65% activated carbon added to the composite material has changed from 22.93 to 97.65 MPa, which is an increase of 325.86%. According to the Scanning electron microscope (SEM) image, a schematic diagram of the internal combination of the composite material is made, the concept of a three‐dimensional network interpenetrating three‐dimensional structure is proposed, and the mechanism of tensile properties enhancement is explained. Obviously, as the carbon content increases, the storage modulus (E′) also increases, and the loss factor (tan δ) and glass transition temperature (Tg) also change. The ability of composite materials to resist pyrolysis has also been enhanced. The above results indicate that BAC as a filler of composite materials can improve various performances.

“…It is believed that biochar not only protects the environment, but also reduces the cost of polymer composites. In our previous study , we reported that the incorporation of biochar increased the processability of UHMWPE and significantly improved its mechanical properties. Moreover, the addition of charcoal could also transform a polymer from an insulating material into a conductive material, demonstrating that charcoal could be an effective candidate for improving the various properties of UHMWPE.…”

Highly filled bamboo charcoal (BC)/ultra‐high molecular weight polyethylene (UHMWPE) composites were prepared using extrusion and hot‐compression molding methods. The addition of BC remarkably improved the tensile properties of UHMWPE composites. When the BC content reached 70 wt%, the tensile strength and Young's modulus rose from 28.0 and 326.6 MPa for the neat UHMWPE to 128.9 and 2,027.7 MPa, increasing by 360 and 520%, respectively. The incorporation of BC also significantly improved the creep resistance, especially at high temperature. The creep strains of the composites with 60, 70 and 80 wt% were reduced by 70.1, 78.3, and 85.2% compared to the neat UHMWPE at 80°C, respectively. To understand the mechanism, the Burger's model was employed to illustrate the influence of BC on the creep performance of the polymer composites. The addition of BC also increased the electrical conductivity of the composites: the composite with 80 wt% BC had a conductivity of 0.53 S/cm. Moreover, the thermal stability of BC/UHMWPE composites improved apparently with the increased charcoal loading. POLYM. COMPOS., 39:E1858–E1866, 2018. © 2018 Society of Plastics Engineers
