Abstract
Metal oxide-polymer composites and methods of preparation.
Claims25
A particulate composition comprising a substrate comprising a metal oxide component and an aluminum oxide component;
- and a metallocene olefin polymerization catalyst component coupled to said substrate.
A composite comprising a nano-dimensioned substrate comprising a metal oxide component, an aluminum oxide component and a metallocene catalyst component;
- and a polyolefin component coupled to said substrate.
A commodity material composition comprising a polyolefin component and a nano-dimensioned substrate component dispersed therein, said substrate component comprising a metal oxide component, an aluminum oxide component and a metallocene catalyst component.
A method of preparing a metal oxide-polyolefin nanocomposite, said method comprising:
- providing a substrate comprising a nano-dimensioned metal oxide component and a metallocene olefin polymerization catalyst component coupled thereto;
- and
- contacting said substrate with an olefin component, said contact for at least one of a time and in an amount sufficient to at least partially polymerize said olefin on said substrate, to provide said nanocomposite.
A method of using an aluminoxane component to moderate phase energy densities of a metal oxide-polyolefin nanocomposite, said method comprising:
- providing a metal oxide component, said metal oxide selected from binary and ternary metal oxides and said oxides comprising a dopant;
- contacting said metal oxide component and an aluminoxane component for a time at least partially sufficient to provide an aluminum oxide coating on said metal oxide component;
- contacting said coated metal oxide with a metallocene olefin polymerization catalyst component, to provide a nano-dimensioned substrate;
- and
- contacting said substrate with an olefin component, said contact for at least one of a time and in an amount sufficient to at least partially polymerize said olefin on said substrate.
