“…Wetting concept is particularly useful in studying filler localization and rubber-filler interactions in binary and ternary rubber blend systems. [15][16][17] Rubber layer L is calculated as a part of wetting concept and it provides information about the bounded rubber layer on the filler surface due to physical and chemical interactions. It is known that rubber layer L development continues until rubber-filler interactions reach to their maximum amount and it remains constant at their plateau value (L P ) after a certain mixing time.…”

“…[1,3,7,8] Besides them, indirect characterization methods have been used to characterize the rubber-filler and filler-filler interactions by utilizing different models with the help of DMA, Fouriertransform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), and nuclear magnetic resonance (NMR). [1,2,4,[13][14][15][16][17][18][19] In addition, researchers [4,18,19] have investigated a variety of approaches to understand the rubber-filler interactions and the internal structures, thus lead the development of concepts like bound rubber and rubber layer L. Since some limitations with the characterization methods have been claimed in many studies and this topic is still open for the research, it was aimed in this study to discuss the features of mostly used direct and indirect methods and concepts to characterize rubber-filler and filler-filler interactions. Moreover, it will be examined if a possible correlation between qualitative and quantitative data obtained by different characterization methods and a relation between rubber-filler and filler-filler interactions exist in the silica-filled SBR and BR polymer mixtures and their blends.…”

Since some decades, styrene–butadiene rubber (SBR) and butadiene rubber (BR) polymers have been used to prepare silica‐filled raw mixtures basing on SBR/BR binary blends for green tire technology. Utilization of high filler concentrations and various components in these complex reinforced rubber systems make the analysis of rubber–filler interactions difficult. Developing new characterization methods and carrying out some methodological characterizations are important for the material and property investigations in this field. In this study, direct and indirect characterization methods mostly used for investigations of rubber–filler and filler–filler interactions, their potential relationships to each other and the problems of characterization methods especially imaging techniques at micro and nanoscale, are discussed for silica‐filled SBR and BR systems.

“…This is seen directly by in situ measurements during mixing (Figure 10). 47,48 For fillers such as carbon nanotubes that are difficult to disperse, the conductivity is mainly observed to increase, since extensive mixing is required to incorporate the particles into the polymer (Figure 11). 49…”

This review describes electrical and dielectric measurements of rubbery polymers. The interest in the electrical properties is primarily due to the strong effect of conductive fillers, the obvious example being carbon black. Conductivity measurements can be used to probe dispersion and the connectivity of filler particles, both of which exert a significant influence on the mechanical behavior. Dielectric relaxation spectra are used to study the dynamics, including the local segmental dynamics and secondary relaxations, and for certain polymers the global chain modes. A recent development in the application of nonlinear dielectric spectroscopy is briefly discussed.

“…Recently, versatile elastomeric materials with excellent mechanical and functional properties have been developed by applying the concept of double percolation, where fillers are selectively distributed and percolated through one of the phases or at the interface of a co-continuous binary blend [ 21 , 22 , 23 ]. Compared with single-phase polymer composites, double percolation demonstrates greater improvements in mechanical, charge storage, electrical, and magnetic properties at lower filler concentrations [ 24 , 25 ]. For instance, selective localization of multi-walled carbon nanotubes in polypropylene/natural rubber blends reduces the rheological percolation threshold by 2 wt.% MWCNTs [ 26 ].…”

Morphology and Microwave-Absorbing Performances of Rubber Blends with Multi-Walled Carbon Nanotubes and Molybdenum Disulfide

This study details microwave-absorbing materials made of natural rubber/nitrile butadiene rubber (NR/NBR) blends with multi-walled carbon nanotubes (MWCNTs) and molybdenum disulfide (MoS2). The mechanical blending method and the influences of fabrication on the morphology and microwave-absorbing performance of resulting compounds were logically investigated. It was found that interfacial differences between the fillers and matrix promote the formation of MWCNTs and MoS2 networks in NR/NBR blends, thus improving microwave-absorbing performance. Compared with direct compounding, masterbatch-based two-step blending is more conducive to forming interpenetrating networks of MWCNTs/MoS2, endowing the resulting composite with better microwave attenuation capacity. Composites with MWCNTs in NR and MoS2 in NBR demonstrate the best microwave-absorbing performance, with a minimum reflection loss of −44.54 dB and an effective absorption bandwidth of 3.60 GHz. Exploring the relationship between morphology and electromagnetic loss behavior denotes that such improvement results from the selective distribution of dual fillers, inducing networking and multi-component-derived interfacial polarization enhancement.
