1. 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.
