Abstract
A composite film may include a discontinuous silver-based functional film, and a PVB over-layer overlying the discontinuous silver-based functional film. The composite film may have an R/sq value of at least about 30 Ohm/sq.
Claims20
A composite film comprising:
- a discontinuous silver-based functional film;
- and
- a PVB over-layer overlying the discontinuous silver-based functional film, wherein the composite film comprises an R/sq value of at least about 30 Ohm/sq.
A laminate comprising:
- a first substrate;
- a discontinuous silver-based functional film overlying a the first substrate;
- a PVB over-layer overlying the discontinuous silver-based functional film, and
- a second substrate overlying the PVB over-layer,
- wherein the laminate comprises an R/sq value of at least about 30 Ohm/sq.

A method of forming a composite film comprising
- providing a silver-based functional film attached to a first surface of a sacrificial film;
- conducting a first lamination of a PVB over-layer onto a second surface of the silver-based functional film, wherein the silver-based functional film is between the PVB over-layer and the sacrificial film;
- and
- conducting a delamination of the silver-based functional film from the sacrificial film to form a discontinuous silver-based functional film attached to the PVB over-layer to form a composite film.
