“…This is in agreement with the results reported earlier by Geyuo et al [12] and Demrihan et al [13]. Mechanical properties decrease drastically after 30 phr loading [12] but when the loading level reaches limit value the activated carbon does not act as reinforcing filler [13].…”

“…Styrene-butadiene rubber (SBR) as a general-purpose synthetic rubber has been widely applied in scientific research and industrial fields owing to its high elasticity, good wear resistance, heat resistance, and aging resistance. − Molecular compositions of rigid styrene (St) and flexible butadiene (Bd) segments of SBRs are known to be well controlled by living anionic polymerization (LAP) to achieve the desired polymer properties. − Moreover, polymerized Bd units can alter microstructures, i.e., various fractions of cis and trans units, 1,2-olefins and 1,4-olefins, which offer structural diversity as a powerful research tool for the design of novel functional materials. − Since the properties of polymeric materials are largely a result of the molecular compositions of polymer chains, the well-tailored construction of polymer chain architecture through quantitative synthesis proves to be a powerful strategy for manipulating polymer properties. , …”

Well-tailored construction of liquid crystal networks (LCNs) with simultaneous molecular mobility and mechanical enhancement is desirable. Since the properties of polymeric materials are largely a result of the molecular compositions of polymer chains, in the present work, we demonstrate the tuning compositional synthesis of anionically polymerized random styrene-butadiene rubbers (r-SBRs) with well-controlled 75 wt % butadiene (Bd) contents that offer molecular mobility. Microstructural 1,2-olefins of 51.5−64.0 mol % were designed to attach 50 mol % SiH-terminated mesogenic moieties (M) along Bd units using hydrosilylation. As mechanical strength usually conflicts with high molecular mobility, an integrated design derived from the orderly LC stacking and simultaneous crosslinking in various ratios of the dynamic 2(6-isocyanatohexylaminocarbonylamino)-6methyl-4[1H]-pyrimidinone (UPy-NCO) and permanent hexamethylene diisocyanate (HMDI) along 1,4-olefins of Bd units offers necessary mechanical strength and molecular mobility, resulting in a series of dynamic LCNs (r-SBR-g-[M•HMDI•UPy]). LC textures, phase transitions, self-healing/welding, and shape memory capacities were comprehensively studied. All LCNs showed LC textures in POM around T i (42−53 °C), which definitely contributed to both mechanical performance and molecular mobility due to the 50 mol % orderly LC stacking. Ureidopyrimidinone (UPy) that forms a dynamic H-bond is beneficial for the temporary shape fixity ratio (R f ), recyclability, and self-healing/welding ability while decreasing the shape recovery ratio (R rec ) because UPy can increase breaking elongations but sacrifice the mechanical strength. However, HMDI that forms a covalent crosslink showed the contrary effect, as HMDI can effectively enhance the mechanical strength but reduce the chain mobility. It is evidenced that r-SBR45k-g-[M-0%, 2%] can hardly undergo shape recovery (R rec = 0) despite R f = 92.6%, while with regard to r-SBR45k-g-[M-10%, 2%], R rec greatly increased to 100%, but R f decreased to 46.2%. All LCNs showed a higher than 82% self-healing/welding efficiency, with an exception of r-SBR-g-[M-10%, 2%]. This indicated the cooperative effect of molecular compositions on the properties. The well-tailored construction of polymer chain architecture through quantitative synthesis proves to be a powerful strategy for manipulating properties.

“…One of the important ingredients added to the rubber, having a significant impact on its properties, is carbon black (CB) in the form of nanoscale particles. Indeed, the rubber industry has used this modification extensively to improve abrasion resistance, elastic modulus, tensile strength, viscoelasticity as well as rheological and conductive properties of elastomeric composites [17][18][19][20][21][22]. However, despite decades of such technology, the actual mechanisms by which CB nanoparticles modify the macroscale properties of rubbers are still not fully understood [23].…”

Effect of Carbon Black Nanofiller on Adhesion Properties of SBS Rubber Surfaces Treated by Low-Pressure Plasma

et al. 2020

View full text Add to dashboard Cite

Studies on the surface modification of commercial styrene-butadiene-styrene (SBS) rubber with different carbon black (CB) nanofiller content (10–80 parts per hundred parts of rubber (phr)) performed by low-pressure oxygen plasma are presented in this paper. The adhesion properties of the rubber were determined by the peel test for adhesive-bonded joints prepared with a water-based polyurethane (PU) adhesive. The chemical structure and morphology of the SBS rubber surface before and after plasma treatment were investigated by X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM), respectively. The peel tests showed that the plasma treatment significantly improved the strength of adhesive-bonded joints in the entire range of CB tested, revealing a clear maximum for approximately 50 phr of CB. It was also found that as a result of plasma treatment, functional groups that are responsible for the reactions with the PU adhesive, such as C−OH and C=O, were formed, and their concentration, similar to the peel strength, showed maximum values for approximately 50 phr CB. The occurrence of these maxima was explained using the bound rubber model.
