Functional devices that manage thermal transport require film structures composed of numerous individual SWCNTs, and the device performance is directly linked to the thermal transport properties of the SWCNT films. In particular, composite SWCNT films blended with multiple types of SWCNTs have the potential to control thermal transport owing to their pseudo-heterogeneous interfaces. However, their properties, including their lattice thermal conductivity, sound velocity, and phonon mean free path (MFP), have not been well investigated. In this study, we investigated the thermal transport properties of composite SWCNT films with pseudo-heterogeneous interfaces that were prepared using SWCNT inks by varying the blending ratio of two SWCNTs (CNT-A and CNT-B). The SWCNT inks were characterized using rheometry and rheoimpedance measurements. SEM images of the composite SWCNT films revealed that the two types of SWCNTs formed independent bundles. Therefore, pseudo-heterogeneous interfaces were obtained between the bundles of each SWCNT. The sound velocity increased for SWCNT films with pseudo-heterogeneous interfaces. However, the thermal conductivity increased linearly with the blending content of CNT-B. The measured phonon MFP of the composite SWCNT films was lower than the linear fitting value that considered only the homogeneous interfaces. This phenomenon occurred because phonon scattering and trapping were enhanced at the pseudo-heterogeneous interfaces in the composite SWCNT films. These findings improve our understanding of the thermal transport in materials with different interfaces.</div></div>","PeriodicalId":11266,"journal":{"name":"Diamond and Related Materials","volume":"159 ","pages":"Article 112925"},"PeriodicalIF":5.1,"publicationDate":"2025-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145332468","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The In-doped BOB demonstrated superior photocatalytic performance in the degradation of Rhodamine B (RhB) compared to pure BOB.

The observed enhancement is due to the synergistic effects of In doping and the formation of the S-scheme heterojunction. Furthermore, In-doped BOB/MCN demonstrated excellent stability. The S-scheme charge transfer pathway was validated through extensive characterization techniques, including XPS and EPR, which confirmed the effective separation of photoinduced charge carriers and the retention of highly active redox electron-hole pairs.

The abundant functional groups of NH₂@MoS₂ coupled with unique layer structure prevents the agglomeration of MXene, facilitates hierarchical porous structures formation, and promotes the specific surface area from 2.65 m²/g (MXene) to 8.27 m²/g (MXMo-6).

A method for forming liquid dispersion for uniform homogenization of carbon nanomaterials within the composite volume has been developed. It was established that exposure of the composite to laser irradiation with a wavelength in the near-infrared spectral range and intensity of 15 kW/cm² leads to a 13-fold reduction in resistance to 8 ± 2 kΩ due to the formation of SWCNT/RGO hybrid nanostructures. It was obtained that the formation of conductive networks in the PDMS matrix resulted in increased defect density due to the formation of bonds between carbon nanomaterials. The study of the dependence of the applied force on the elongation of the formed composites with different compositions showed that the sample based on the PDMS/SWCNT/RGO composite possessed the highest strength. The elastic modulus value of the fabricated PDMS/SWCNT/RGO composite electrodes (180.0 ± 5.3 kPa) correlates well with the elastic modulus of skin. The study of the influence of mechanical pressure on the impedance of the formed electrodes showed that an increase in pressure (0–100 mmHg) leads to a decrease in impedance across the entire frequency range of 10–1000 Hz. The PDMS/SWCNT/RGO composite electrodes demonstrated high stability of impedance-frequency dependence in the same frequency range during prolonged contact (7 days) with a sweat-simulating suspension compared to conventional Ag/AgCl electrodes. In addition, the high stability of the PDMS/SWCNT/RGO composite electrodes was confirmed by a 14-day recording of impedance changes during their on-skin placement. During ECG measurements, it was found that the signal quality recorded by PDMS/SWCNT/RGO composite electrodes was comparable to that from Ag/AgCl electrodes, while the amplitudes of main peaks were sharper. The biocompatibility of PDMS/SWCNT/RGO composite electrodes was demonstrated in studies of connective tissue cell viability on their surface. It was established that the cell count on PDMS/SWCNT/RGO composite corresponded to the cell count on the control sample. Thus, the developed PDMS/SWCNT/RGO composite electrodes can be used for wearable devices, including continuous ECG monitoring for at least 7 days.
