A Double‐Helix Metal‐Chain Metal‐Organic Framework as a High‐Output Triboelectric Nanogenerator Material for Self‐Powered Anticorrosion

Abstract

The development of novel metal organic framework (MOF) friction power generation materials with high stability is important. This paper reports the first example of a double-helix metal chain organic framework with a network structure (ZUT-8). ZUT-8 shows high chemical stability, functional adjustability, and excellent output performance of friction power generation, which is superior to traditional coordination polymer materials. The cathodic protection system with ZUT-8 can prevent metal corrosion significantly. The output performance can be improved effectively by enhancing the conjugate effect of the linker. The theoretical calculation results showed that an increase in the degree of conjugation could significantly reduce the band gap, thereby affecting the friction power output signal. This study opens the door to constructing MOF materials with a double-helix metal chain and will promote their potential applications in self-powered electrochemical cathodic protection.

Research of electret air filter: A review

“…76 By controlling the contact separation or relative sliding between two materials with opposite frictional properties, mechanical energy can be converted into electrical energy. [77][78][79] The combination of TENG with air materials provides a continuous charge, which solves the problem of charge dissipation. TENG have three advantages over triboelectricity: (1) they can harness energy from the environment, eliminating the need for an external power supply for the air filtration system 80,81 ; (2) they operate without generating air power, resulting in zero ozone emissions 82 ; and (3) strong electrostatic attraction can efficiently eliminate particles ranging from nano-to micron-sized.…”
