Abstract
An article of a plastic substrate and a bond layer of a plasma polymerized cyclosiloxane having select unsaturation and a method of forming same.
Claims28
An article comprising:
- a plastic substrate;
- and
- a bond layer on a surface of said plastic substrate, said bond layer comprising a plasma reacted cyclosiloxane, said cyclosiloxane having at least one C2 to C10 alkenyl group attached to a silicon atom.
An article comprising:
- a thermoset or thermoplastic substrate;
- and
- a bond layer on the surface of said substrate, said bond layer comprised of a plasma reacted cyclosiloxane, said cyclosiloxane having one C2 to C6 alkenyl group attached to a silicon atom, said cyclosiloxane being a cyclotrisiloxane, a cyclotetrasiloxane or a cyclopentasiloxane.
A multilayer article comprising:
- a polycarbonate substrate;
- and
- a bond layer on the surface of said polycarbonate substrate, said bond layer comprising plasma reacted heptamethyl(vinyl)cyclotetrasiloxane.
A method of forming a multilayer article comprising:
- providing a plastic substrate;
- and
- plasma reacting a cyclosiloxane onto a surface of said plastic substrate to form a bond layer, said cyclosiloxane having at least one C2 to C 0 alkenyl group attached to a silicon atom.
A method of forming a multilayer article comprising:
- providing a thermoset or thermoplastic substrate;
- and
- plasma reacting a cyclosiloxane onto a surface of said substrate to form a bond layer, said cyclosiloxane having one C2 to C6 alkenyl group attached to a silicon atom, said cyclosiloxane being a cyclotrisiloxane, a cyclotetrasiloxane, or a cyclopentasiloxane.
A method of making a multilayer article comprising:
- providing a polycarbonate substrate;
- and
- plasma reacting heptamethyl(vinyl)cyclotetrasiloxane onto a surface of said polycarbonate substrate to form a bond layer.
