Dispersed Detonation Nanodiamond Composites

Summary

Researchers at Vanderbilt University have developed a revolutionary method for incorporating nanodiamond particles into an existing polymer matrix. The resulting composite materials have greatly enhanced mechanical and chemical properties that can be tailored during this process.

Addressed Need

• Polymer composites have a wide variety of applications due to the ability to chemically optimize material properties to fit the intended use

• Scientists are constantly looking for ways to extend the limits of these various properties, such as strength or stiffness, or to expand the utility of these materials

• Conventional methods for creating enhanced polymer composites, such as fiber reinforcement, are too expensive for the small mechanical enhancements that they provide

Technology Description

This novel technology consists of a materials system wherein nanodiamond particles are dispersed in a polymer matrix, resulting in a nanocomposite material with significantly enhanced mechanical properties. The synthesis of this material system takes place in three parts. First, a dispersion of deaggregated nanodiamond is obtained, then the surface chemistry of the nanodiamond particles is optimized to ensure compatibility with the target polymer. Finally, carrier solvents involved in the process are removed by a vacuum distillation process. Incorporating these nanoparticles enables tunable improvements to be made to the chemical and mechanical properties of the polymer.

Unique Features and Competitive Advantages

• Diamond nanoparticles are very effective at improving a polymer’s stiffness, strength, chemical resistance, thermal conductivity, glass transition temperature, and UV-stability

• Using this technique, stiffness and strength enhancements can be achieved without sacrificing other important parameters, such as ductility

• There is a nearly limitless range of polymer systems in use today, and this technology has the potential to benefit the large majority of them

Technology Development Status

This technology has been successfully applied to multiple polymer systems, and the utility of this technology has been proven
