Abstract
The present invention provides a method for the effective dispersion of carbon nanotubes into a polymer matrix. Through a combination of dispersion through sonication, in situ polymerization, dissolution, and film casting, transparent polymer carbon nanotube composites are produced.
Claims22
A method of preparing a polymer-carbon nanotube composite, the method comprising:
- providing an inhibited monomer composition
- deinhibiting said monomer;
- dispersing carbon nanotubes in the deinhibited monomer;
- adding an initiator to the resulting dispersion;
- polymerizing the monomer in the presence of the dispersed nanotubes to form a composite;
- and
- dissolving the resulting composite in a solvent.

A method of preparing a polymer-carbon nanotube composite, the method comprising:
- deinhibiting a methyl methacrylate monomer;
- placing single-wall carbon nanotubes into the deinhibited monomer, forming a nanotube mixture;
- sonicating the nanotube mixture for a duration sufficient to disperse the nanotubes in the monomer;
- placing the dispersed mixture into a reaction vessel;
- adding a 1-phenyl-2-hydroxy-2-methyl-1 propanone initiator to the reaction vessel;
- bubbling nitrogen gas through the mixture for a duration sufficient to allow for a nitrogen environment in the mixture;
- polymerizing the monomer in the presence of the dispersed nanotubes to produce a composite;
- and
- dissolving the resulting composite in methylene chloride.
