Covalent Graphene-Metal-Organic Polyhedra Hybrids: Triboelectric Nanogenerators for Next Generation of Wearable E-Skin Technologies. SMALL (WEINHEIM AN DER BERGSTRASSE, GERMANY) 2025:e2503772. [PMID: 40304171 DOI: 10.1002/smll.202503772] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/24/2025] [Revised: 04/18/2025] [Indexed: 05/02/2025]
Abstract
The development of stretchable energy-harvesting devices that convert mechanical stimuli into electrical energy is crucial for advancing self-powered electronic skin (e-skin) technologies. Triboelectric nanogenerators (TENGs) show promise but suffer from low stretchability, limited conductivity, and poor mechanical durability. Here, we report a new generation of TENGs designed via the molecular chemistry of metal-organic polyhedra (MOPs) covalently bonded to functionalized 2D nitrogen-doped graphene sheets (NG@MOP). The resulting NG@MOP hybrids, featuring aromatic regions and surface amine groups, link to anionic nickel-based MOPs, [Ni8(HImDC)12]8-, through amide bonds. This hybrid exhibits a large surface area, hierarchical micro-mesoporous channels, and structural defects, improving mechanical resilience. Incorporating NG@MOP into a polyurethane matrix produces a highly stretchable, biocompatible film withstanding over 500% strain. The composite delivers excellent triboelectric output, generating 417 V and 10.8 µA at 5 wt % loading. Applied as a wearable e-skin, the device maintains functionality under extreme deformation, demonstrating a strain sensitivity of 13 mV per degree of motion. It efficiently detects subtle body motions such as bending and stretching, showing strong potential for wearable motion sensing and real-time health monitoring.

NANOMATERIALS (BASEL, SWITZERLAND) 2025; 15:145. [PMID: 39852760 PMCID: PMC11767271 DOI: 10.3390/nano15020145] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/31/2024] [Revised: 01/17/2025] [Accepted: 01/18/2025] [Indexed: 01/26/2025]
Abstract
The exploitation of high-performance third-order nonlinear optical (NLO) materials that have a favorable optical limit (OL) threshold is essential due to a rise in the application of ultra-intense lasers. In this study, a Cu-based MOF (denoted as Cu-bpy) was synthesized, and its third-order NLO and OL properties were investigated using the Z-scan technique with the nanosecond laser pulse excitation set at 532 nm. The Cu-bpy exhibits a typical rate of reverse saturable absorption (RSA) with a third-order nonlinear absorption coefficient of 100 cm GW-1 and a favorable OL threshold of 0.75 J cm-2 (at a concentration of 1.6 mg mL-1), which is lower than that of most NLO materials that have been reported on so far. In addition, a DFT calculation was performed and was in agreement with our experimental results. Furthermore, the mechanism of the third-order NLO properties was illustrated as one-photon absorption (1PA). These results investigate the relationship between the structure and the nonlinear optical properties of Cu-bpy, and provide an experimental and theoretical basis for its use in optical limiting applications.

Abstract
This study presents a novel approach utilizing solvothermal techniques to synthesize zeolitic imidazolate framework (ZIF‐4) particles. Various properties of the ZIF‐4 particles are investigated to shed light on the structural and morphological characteristics. These ZIF‐4 particles act as a positive triboelectric layer in the fabrication of a triboelectric nanogenerator (TENG) designed for powering electronic devices. The solvothermal‐assisted synthesis ensures the controlled and efficient production of ZIF‐4, optimizing its characteristics for enhanced performance in the TENG. The generated TENG, based on ZIF‐4 particles, determines promising capabilities in converting mechanical energy into electrical power. The highest power of TENG is obtained to be 18 μW at a load resistance of 50 MΩ. This work contributes major insights to the search for sustainable and effective power solutions for electronic gadgets. It emphasizes the potential of ZIF‐4 as a crucial triboelectric material, demonstrating its importance in the advancement of TENGs.

Abstract
New stable frictional materials based on metal-organic frameworks (MOFs) are greatly desired for applications in self-powered systems. This work reports an ionic MOF material with efficient charge separation mediated by charge induction. ZUT-iMOF-1(Cu) is chemically stable and its triboelectric output performance surpasses those of traditional MOF materials. The short-circuit current of the iMOF triboelectric nanogenerator is 73.79 μA at 5 Hz. The output performance remains stable over 50 000 cycles of continuous operation. The charge and power densities peak at 123.20 μC m-2 and 3133.23 mW m-2. Owing to its high output performance, ZUT-iMOF-1(Cu) effectively prevents metal corrosion in cathodic-protection systems. Theoretical calculations show that increasing the charge-separation effect promotes the frictional electricity generation behaviour. This study provides research suggestions for ionic MOF frictional materials and will promote their application in self-powered electrochemical cathodic-protection systems.
