Abstract
A nanocomposite material comprises polyethylene terephthalate (PET) as a base polymer and a nanoparticle that increases the strength of the base polymer.
Claims8
A masterbatch product suitable for injection molding, comprising a base polymer including a polyethylene terephthalate (PET);
- and graphene nanoplatelets that are compounded with the base polymer to form the masterbatch product suitable for injection molding, wherein the graphene nanoplatelets comprise from two to fifteen percent by weight of the masterbatch and the graphene nanoplatelets have an average diameter of 5 micrometers.
A masterbatch product suitable for injection molding, comprising a base polymer comprised of polyethylene terephthalate (PET);
- and graphene nanoplatelets that are exfoliated and have an average diameter of 5 micrometers and that are compounded with the PET to form the masterbatch product, such that the graphene nanoplatelets comprise between ten and fifteen percent by weight of the masterbatch product.
A method for forming a masterbatch product suitable for injection molding, comprising:
- obtaining a polyethylene terephthalate (PET) base polymer;
- providing exfoliated graphene nanoplatelets having an average diameter of 5 micrometers;
- wherein said exfoliated graphene nanoplatelets comprise from two to fifteen percent by weight of the masterbatch product;
- compounding the base polymer and graphene nanoplatelets to create the masterbatch product.
