Abstract
A scratch and ultraviolet resistant film includes a polymer-carbon composite film configured to be applied as a thin film on a substrate. The polymer-carbon composite film includes a resin such as a thermoset resin and/or a thermoplastic resin, and between about 0.25 wt. % and about 5 wt. % graphene disposed in the resin. In addition, the polymer-carbon composite film applied as the thin film on the substrate has a thickness between about 0.2 mm and about 1 mm.
Claims20
A scratch and ultraviolet (UV) resistant film comprising:
- a first polymer-carbon composite film comprising:
- a resin selected from at least one of a thermoset resin and a thermoplastic resin;
- and
- between about 0.25 wt. % and about 5 wt. % graphene disposed in the resin,
- the first polymer-carbon composite film configured to be applied as a thin film on a transparent substrate with a first side and a second side opposite the first side,
- wherein the first polymer-carbon composite film is disposed on the second side, an electrochromic film is disposed on the second side and sandwiched between the first polymer-carbon composite film disposed on the second side and a second polymer-carbon composite film, and a polyvinyl butyral film is disposed between the second side and the first polymer-carbon composite film.
A scratch and ultraviolet (UV) resistant film comprising:
- a first polymer-carbon composite film comprising:
- a polyethylene terephthalate (PET) resin;
- and
- between about 0.25 wt. % and about 5 wt. % graphene disposed in the PET resin, the first polymer-carbon composite film configured to be applied as a thin film on a transparent substrate with a first side and a second side opposite the first side,
- wherein the first polymer-carbon composite film is disposed on the second side, an electrochromic film is disposed on the second side and sandwiched between the first polymer-carbon composite film disposed on the second side and a second polymer-carbon composite film, and a polyvinyl butyral film is disposed between the second side and the first polymer-carbon composite film.
A scratch and ultraviolet (UV) resistant film comprising:
- a first polymer-carbon composite film comprising:
- a polyethylene terephthalate (PET) resin;
- and
- between about 0.4 wt. % and about 1.0 wt. % graphene disposed in the PET resin,
- the first polymer-carbon composite film configured to be applied as a thin film on a transparent substrate with a first side and a second side opposite the first side,
- wherein the first polymer-carbon composite film is disposed on the second side, an electrochromic film is disposed on the second side and sandwiched between the first polymer-carbon composite film disposed on the second side and a second polymer-carbon composite film, and a polyvinyl butyral film is disposed between the second side and the first polymer-carbon composite film.
