Abstract
A transparent solar control film may have a single or multiple layer core that includes at least one layer of an orientated thermoplastic polymer material. Infrared radiation absorbing nanoparticles that preferentially absorb at least about 100 times more infrared radiation than visible radiation may be dispersed within the at least one layer of an oriented thermoplastic polymer layer. The transparent solar control film may have a haze value of less than about 5 percent.
