技術應用

The new material can be used to make nanoelectronics and electronic devices such as sensors, organic field effect transistors (FET), photovoltaic cells, biomolecular imaging and detection, and energy storage devices such as fuel cells, batteries, super capacitor, etc. For example, the efficiency of CNT FET devices with polymer supramolecular structures is 100 times higher than that of standard polymer thin film FETs.

詳細技術說明

Two carbon allotropes, carbon nanotubes (CNTs) and graphene, have valuable mechanical, thermal, and electrical properties. The lack of a simple and versatile system to disperse and functionalize CNTs and graphene for commercial use often prevents these valuable properties from being utilized in the fabrication of various electronic devices. This technology describes a new nanomaterial containing: 1. at least one CNT or graphene structure with an outer surface, and 2. a large number of crystalline polymer supramolecular structures (including a conjugated polymer) which are non-covalently secured to the outer surface of the CNTs or graphene structure. The supramolecular structures of crystalline polymers look like tentacles protruding from the outer surface of the CNTs or graphene structure.

*Abstract

Method to functionalize CNTs and graphene, while maintaining valuable mechanical, thermal, and electrical properties, by non-covalently attaching (at least partially conjugated) polymers to CNTs or graphene structure. Functionalized CNTs and graphene can then be used in the fabrication of various electronic devices such as sensors, energy storing devices, and field effect transistors (FETs).
