Abstract
A nanocomposite material comprises polyethylene terephthalate (PET) as a base polymer and a nanoparticle that increases the strength of the base polymer.
Claims6
A nanocomposite material comprising:
- a polyethylene terephthalate base polymer;
- and
- exfoliated graphene nanoplatelets compounded with said polyethylene terephthalate base polymer to increase strength of the polyethylene terephthalate base polymer, wherein said exfoliated graphene nanoplatelets are present between about two percent and fifteen percent by weight of the nanocomposite material.
A method of producing masterbatch pellets, the method comprising:
- providing a polyethylene terephthalate base polymer;
- providing between about two percent and fifteen percent by weight exfoliated graphene nanoplatelets;
- compounding the polyethylene terephthalate base polymer with the exfoliated graphene nanoplatelets so as to obtain exfoliated graphene nanoplatelets dispersed in the polyethylene terephthalate base polymer;
- and, forming masterbatch pellets from the exfoliated graphene nanoplatelets dispersed in the polyethylene terephthalate base polymer.
