Piezoelectric Nanogenerators Based on Metal-Organic Skeleton (Mof-5) and Multiwall Carbon Nanotube (Cnt) Composites for Intelligent Human-Machine Interaction

Published: Jan. 1, 2024

Carbon nanotubes (CNTs), as one-dimensional conductive non-metallic materials, exhibit excellent electrical properties. However, the degradation of properties due to defects in modified carbon and agglomeration interfacial effects hinder their broader applications. MOF-5, a type isoreticular metal-organic framework (MOF), features highly porous structure presence metal active centers, offering superior catalytic activity. Their high crystallinity good provide necessary conditions for synergistic utilization piezoelectric nanogenerators (PENGs). Nevertheless, there has been lack precedent PENG system MOF nanotube composites, primarily challenges integration into suitable polymer matrix.
