Abstract

A nanocomposite material comprises polyethylene terephthalate (PET) as a base polymer and a nanoparticle that increases the strength of the base polymer.

Claims (12)

1. A nanocomposite material consisting essentially of:

a base polymer including polyethylene terephthalate (PET); and

exfoliated graphene nanoplatelets compounded into the PET to increase the strength of the base PET, the graphene nanoplatelets comprising from ten to fifteen percent by weight of the nanocomposite material, wherein the graphene nanoplatelets have an average diameter of 5 micrometers.

2. The material of claim 1 , wherein the graphene nanoplatelets comprise ten percent by weight of the nanocomposite material.

3. The material of claim 1 , wherein the graphene nanoplatelets comprise 15 percent by weight of the nanocomposite material.

4. A method of producing a nanocomposite material consisting essentially of:

providing polyethylene terephthalate (PET) as a base polymer;

providing an exfoliated graphene nanoparticulate material, the exfoliated graphene nanoparticulate material comprising from ten to fifteen percent by weight of the nanocomposite material;

compounding the base polymer with the exfoliated graphene nanoparticulate material to form a masterbatch product; and

injection molding the masterbatch product, wherein the graphene nanoparticulate material have an average diameter of 5 micrometers.

5. The method of claim 4 , wherein providing the graphene nanoparticulate material further comprises providing ten percent by weight of the nanoparticle material in the masterbatch product.

6. The method of claim 4 , wherein providing the graphene nanoparticulate material further comprises providing fifteen percent by weight of the nanoparticle material in the masterbatch product.
