2020年8月13日 · The CNT-PDMS composite has been widely adopted in flexible devices due to its high elasticity, piezoresistivity, and biocompatibility. In a wide range of applications, CNT-PDMS composite sensors were used for resistive strain measurement.

2023年1月7日 · As a widely used material in TENG electrodes, polydimethylsiloxane (PDMS) shows attractive characteristics, such as electron affinity, flexibility, and facile fabrication. To achieve...

2018年1月22日 · In this study, we propose a simple, fast, and cost-effective fabrication method for a homogenously hybridized CNT/polydimethylsiloxane (PDMS) composite with high conductivity, stretchability,...

2023年9月29日 · Here, we report a design approach based on the collaboration of double structure and electrical characteristics that can improve sensor sensitivity at high pressure. The surface microstructural and internal porous structure of the dielectric layer provide a more comprehensive deformation range for the sensor from a mechanical perspective.

6 天之前 · The sensitivity of modern flexible sensors based on reduced graphene oxide (rGO), CNT and PDMS has seen significant improvements, now extending to 4.4% N –1 in the low force range (<10 N), 1.8% N –1 in the medium force range (10–30 N) and 0.19% N –1 in the high force range (30–100 N) but its thickness is ∼2 cm. In addition ...

2024年6月11日 · Inspired by the self-cleaning property of the surface microstructure of lotus leaves, we have designed a superhydrophobic flexible sensor of L-CNT@PDMS by a template method and a laser direct writing technique. Single-walled carbon nanotubes (CNTs) were incorporated into poly (dimethylsiloxane) (PDMS) to prepare a CNT@PDMS elastomer.

2025年3月27日 · The prepared CNT/GNP-PDMS composite film was cut into a rectangle of 10 mm × 20 mm, and then the microstructure/planar structure pressure sensor based on oriented conductive network was obtained, as shown in Fig. 1 b. Specifically, firstly, the CNT/GNP-PDMS microstructured material was assembled by docking with the planar structured material.

4 天之前 · The cavity was framed to hold the CNT/PDMS composite [21,22]. The process is shown in Figure 2. 2.2. CNT/PDMS Composite Preparation 2.2.1. Materials. The electrodes were fabricated using SWCNT-COOHs, which were purchased from Nano Research Elements (Haryana, India) with specifications shown in Table 1. Functionalized SWCNTs were chosen for ...

The functionalization of carbon nanotubes (CNT) with different functional groups influences its colloidal behavior in polydimethylsiloxane (PDMS) and enhances the interfacial interaction between the CNTs and PDMS. This paper addresses the investigation of the effect of CNT functionalization on pressure sensing behaviour of CNT-PDMS nanocomposites.
