“…Another research team (Yang et al [ 27 ]) proposed a study similar to the above studies but modified the strategy for manufacturing of CNT/G/PDMS composites. They used a combination of solution blending (in THF) and sonication processes assisted by the mixture of cetyltrimethylammonium bromide (CTAB), p-octyl polyethylene glycol phenyl ether (OP-10) compound dispersant, and sodium dodecyl sulfate (SDS) anionic surfactant.…”

This review is dedicated to versatile silicone rubber composites based on carbon nanotube/graphene (CNT/G) hybrid fillers. Due to their unique mechanical, electrical, thermal, and biological properties, such composites have enormous potential for medical, environmental, and electronics applications. In the scope of this paper, we have explored CNT/graphene/silicone composites with a different morphology, analyzed the synergistic effect of hybrid fillers on various properties of silicone composites, and observed the existing approaches for the fabrication of hybrid composites with a seamless, assembled, and/or foamed structure. In conclusion, current challenges and future prospects for silicone composites based on CNTs and graphene have been thoroughly discussed.

“…Although many researchers have studied the polydimethylsiloxane (PDMS) composites with either CNTs or graphene fillers, there have been few studies on properties of silicone composites containing CNT–graphene hybrid materials [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 , 26 ]. In particular, Hu et al [ 16 ] investigated the dispersion of G/CNTs hybrid fillers in silicone rubber.…”

“…However, the composite fabrication techniques employed in these studies have some significant drawbacks for biomedical applications. In particular, the production of G/CNT hybrid fillers has been carried out mainly through a solution blending method involving the use of solvents (tetrahydrofuran [ 16 , 17 , 18 , 19 ], hexane [ 20 , 21 ], acetate [ 23 ], toluene [ 24 ], etc. ), which can affect the toxicity of ultimate composites and contribute to the deterioration of their electrical and mechanical properties.…”

Biocompatible, Electroconductive, and Highly Stretchable Hybrid Silicone Composites Based on Few-Layer Graphene and CNTs

In this paper, we report a cost-effective and scalable approach to produce highly homogeneous graphene and CNT-based silicone composites with potential applications in diverse fields of research, including biosensors and wearable electronics. This approach includes the fabrication of hybrid fillers based on few-layer graphene and CNTs by water solution blending and manufacturing of graphene/CNT/PDMS composites through calendering in a three-roll mill. The influence of processing parameters, the graphene/CNT ratio, and hybrid filler loading was thoroughly investigated, and the optimal parameters for producing hybrid composites with superior electrical and mechanical properties were found. It was also confirmed that the graphene/CNT hybrid system exhibits a synergistic effect of non-covalent interactions between graphene sheets and CNT sidewalls. This synergistic effect prevents the aggregation of graphene sheets, facilitates the dispersion of graphene and CNTs in the silicone matrix, and contributes to the superior properties of hybrid composites compared to composites with either of these fillers alone.

Abstract3D printing electronics provides great potential to build structural objects with multiple functionalities, with the assistance of shape design and the shear force on the filler orientation. In the study, nano–microanisotropic sensors with oriented fillers assure its linear sensitive properties, where the sensors are 3D‐printed based upon the carbon fiber (CF)‐ and multiwalled carbon nanotube (MCNT)‐filled polydimethylsiloxane (PDMS). The synergistic effect of CF and MCNT modifies the printability, mechanical properties, and sensitivity of printed sensors. The introduction of anticatalyst and catalyst guarantee the printable mixtures with a stable printability in a long term (>15 days). Assisted by the shear flow, the fillers own the orientation ration of 78.53%, which further contribute to the linear sensing behaviors under the tensile strain of 0–20% and compressive stress of 0–20 kPa. Frequency‐domain signals and visual demonstration on the cyclic stretch test reveal that the double peak is originated from the hysteresis of the strain to applied stress. Anisotropic electromechanical behaviors of the resistors will inspire to quantitatively analyze multidimensional strains in practical applications. The fingerprint inspired resistors with multiple sensing signals further demonstrate the convenience of the printing process on the design of wearable electronics.
