Abstract
The present invention provides a chemically bonded carbon nanotube-polymer hybrid and the nanocomposite thereof, having the following advantages: functionalizing carbon nanotubes and also effectively having the carbon nanotube covalently bonded with a wide variety of polymers, even for stable and non-reactive polymers, such as commercially available polymers and high performance engineering plastics. The nanocomposite material according to the invention, compared to its matrix polymer, has higher mechanical strength, conductivity, proton conductivity, and heat stability.
Claims13
A method for forming chemically bonded carbon nanotube-polymer hybrid, comprising:
- providing a polymer;
- performing an ozone-mediated process to the polymer to form at least one reactive moiety at the polymer;
- and
- providing at least one carbon nanotube, wherein the at least one carbon nanotube is chemically bonded to the at least one reactive moiety of the polymer to produce the nanotube-polymer hybrid.
A method for forming nanocomposite, comprising:
- providing at least one first polymer, wherein said first polymer is processed by an ozone-mediated process to form at least one reactive moiety on the polymer chain of said first polymer;
- providing at least one carbon nanotube, wherein said carbon nanotube is chemically bonded to the polymer chain of the first polymer by reacting with the at least one reactive moiety on the polymer chain of said first polymer to form a nanotube-first-polymer hybrid;
- and
- providing at least one second polymer, wherein a polymer matrix of said second polymer is dispersed with the nanotube-first-polymer hybrid.
