In this study, the synergistic effect created by adding Graphene (GE) nanoplatelets and carbon black (CB) fillers to the rubber matrix was used to determine the high stretchable sensor properties. GE and CB-filled rubber nanocomposite (HcN) strain sensors have been shown to detect and trace crack initiation and crack propagation of different sizes under cyclic loading. Tests were performed with four different crack sizes (0, 2.5, 5, and 10 mm) at five different strain levels (0%, 5%, 10%, 15%, and 20%) to determine the strain sensing performance of the specimens. The electrical response of HcNs under loading was measured with the four-point probe technique and recorded with a high-performance data acquisition system. The progression of external cracks created by scalpel on HcNs was examined by measuring electrical resistance changes caused by cyclic strain loading between 0% and 20%. The electrical response of 4 phr and 8 phr filled HcNs behaved qualitatively similar to each other, while 1 phr filled HcNs showed a significantly different response in terms of quality and quantity. In 4 phr GE-filled specimens, the resistance increase was changed steadily depending on the crack length, and unstable conditions occurred at 5 and 10 mm crack lengths at 1 and 8 phr GE filler ratios. The flexible and stretchable elastomer-based conductive strain sensing sensors, developed with the synergistic interaction of well-dispersed carbon-based fillers in the matrix, can detect and record damaged conditions caused by cyclic loading in many application areas.

“…In Figure 6A-D, it is seen that all blends had similar G 0 values in the high-frequency region, while they differed in the low-frequency region depending on the blend composition. Therefore, in accordance with the literature, [43,44] modulus values in the low-frequency region were considered in the structural and viscoelastic analysis. In the examination of the modulus values in the low-frequency region, it is seen that the blend samples which were prepared by COC(E140), COC(8007) and COC(6013) showed frequency-dependent behavior while the samples containing COC(6017) at rates higher than 50% in wt% showed frequency-independent modulus behaviors, which were similar to those revealed in rheological analyses of polymer composites containing solid fillers above the percolation threshold.…”

In this study, blends of cyclo-olefin copolymers (COC) that had different monomer compositions and poly(Acrylonitrile-Butadiene-Styrene) (ABS) were prepared and variations in their morphological, rheological, and dynamic mechanical properties were investigated. In the morphological analyses, it was seen that all blends with 50/50% composition had a co-continuous morphology, while droplet-matrix morphology was observed for the other compositions. Melt-state shear modulus and viscosity increased with the addition of ABS for the blends prepared with COC derivatives containing 40% and ⁓68% norbornene content by weight, while there was no significant change in the modulus values of those prepared with the COC derivative containing ⁓76% norbornene by weight. On the contrary to other blends, it was observed that the modulus values decreased with the addition of ABS in the blends prepared with COC with 82% norbornene content. Evaluation of the SEM images and Cole-Cole plots indicated that COC-rich blends were more compatible than the ABS-rich blends in the case COC with lower norbornene content was used in polymer blends, while ABS-rich blends became more compatible with increasing norbornene content of COC.
