“…The second origin of silicon elements can be the addition of silica nanoparticles as a co‐filler to CB particles in the processing step of samples. Such binary fillers offer a combined advantage such as low hysteresis, good abrasion resistance, and reinforcement 30 . The N1s asymmetric peaks centered at 401 eV is well observed (Figure S5) for irradiated composites at different fluencies and PN 31 .…”

Interest in the phenomenon of laser ablation (LA) has gained significant attention in recent years due to its potential for machining, high‐precision drilling, and cutting materials, such as metals, semiconductors, and dielectrics. Here, LA of ethylene‐butyl acrylate (EBA) filled with different volume fractions (4%, 8%, and 20%) of CB particles is studied. Upon irradiation with the second harmonics (532 nm) of the nanosecond pulsed Nd:YAG laser, a structuration is evidenced at the sample surface in a restricted range of fluence and at high pulse number (PN) (500 pulses, 1 Hz). The laser‐ablated surface is analyzed by microtopography, scanning electron microscopy (SEM), and x‐ray photoelectron spectroscopy (XPS). Collectively, our data show a lowering in ablation threshold and depth for CB volume fractions larger than the conduction threshold (8%), indicating that visible radiation primarily induces photothermal effects. After redeposition of the ablation products at the surface, XPS indicates that high CB content in the EBA matrix induces high oxidation level of the composite surface. Furthermore, our results reveal that LA produces a significant proportion of amorphous carbon. Several parameters which affect heat accumulation and CB particle shielding are discussed. Such parameters include laser fluence and repetition rate, and CB content.

Anisotropy of the internal damage caused by imposed deformation, which is called stress-softening or Mullins effect, was investigated for a carbon-black (CB) filled styrene butadiene rubber (SBR/CB) by a sequence of two tensile measurements. A wide-width pristine sheet specimen satisfying pure shear (planar) stretching geometry was first subjected to a single loading-unloading cycle with a maximum stretch (λ m ). The rectangular subsamples were cut out from the unloaded and relaxed sheet specimen such that the long axis had an angle of θ = 0° or 90° relative to the pre-stretching axis. Subsequently, uniaxial stretching of the subsamples was conducted, and the internal damage (D 0 or D 90 ) at each angle was evaluated as a function of λ m from the difference in the uniaxial stress-strain data between the subsamples and the pristine samples. Almost no anisotropy ( f = D 0 /D 90 ≈ 1) was observed for the internal damage in the moderate λ m regime of λ m < 3. This is in contrast to a large damage anisotropy ( f ≈ 3) in the corresponding λ m regime previously reported for a silica filled SBR with silane coupling agent (SBR/Silica). The f values for SBR/CB in the high λ m regime of λ m > 3 increased with λ m and became comparable to those in SBR/Silica. The significantly large difference in the internal damage anisotropy between SBR/CB and SBR/Silica reflects the differences in the types of destructed molecular bonding for the filler networks and filler/rubber interfaces between the two elastomers.

“…Consequently, depending on the specifications, a modern tyre tread may contain 50-100 phr of silica and as little as 10 phr of carbon black in case minimal rolling resistance is required. [6][7][8][9][10] Tyre recycling is challenging because they are often made of various polymer blends, consist of up to 100 various additives, and have a cross-linked structure. Currently, only downcycling options are available for rubber waste management companies.…”

The complex structure of tyres makes them hard to recycle economically; hence, it is crucial to minimize the generation of tyre waste. Nano‐reinforcement, such as graphene, has the potential to increase the abrasion resistance of rubber and thus their lifespan as well. In this research, hybrid styrene‐butadiene rubber‐based (SBR) nanocomposites reinforced with carbon black, silica and various amounts of graphene nanoplatelets are investigated with great emphasis on their combined effects on the mechanical properties of the rubber samples. Sixty‐five phr of precipitated silica can holistically improve the properties of SBR. However, further addition of carbon black and graphene nanoplatelets to silica‐containing samples do not benefit the properties of the samples. Further studies on the compatibilization of silica with carbon‐based reinforcement are necessary. On the other hand, graphene and carbon black constitute an effective hybrid reinforcement system. The tensile strength and elongation at break of SBR are improved by almost 100% with 10 phr of graphene nanoplatelets in combination with 10 phr of carbon black. However, the abrasion resistance of samples was negatively influenced by the addition of graphene nanoplatelets whenever it was added in combination with other fillers. Silica was particularly effective in increasing the abrasion resistance of rubber.
