Applications for nanotubes are numerous in all sectors where composites are needed. Successful applications require chemical modifications and these can be done using the offered technologies. With economical production of carbon nanotubes and their incorporation into advanced materials, the invented technologies will open a whole new world of possibilities for an array of industrial applications.
How it works
Carbon nanotubes have the best mechanical, electrical and thermal properties of any known material. They hold great promise for many technologies and applications. Technologies presented here provide an economical way to scale up chemical modifications of single, double and multi wall nanotubes (SWCNT, DWCNT and MWCNT) for integration into thermosets, thermoplastics and elastomers. Our solutions provide a number of methods for attaching functional compounds to carbon nanotubes. For example, attached compounds can be block polymers to adjust plasticity. Furthermore, side walls of carbon nanotubes can be chemically modified to form a polymer-coated CNT. The polymer shell of the modified CNT can covalently connect to another polymer, allowing for effective integration into a variety of advanced composite materials. These methodologies are the first to modify CNTs and allow for their integration into composites without modifying their mechanical and electrical properties, without isolation of intermediaries and without addition of any catalysts to form the polymer shell.
