Publication number: 20170003424Abstract: Infrared and ultraviolet reflecting films and methods for producing the films using metal oxide particles such as TiO2 or ZnO fibers that have been decorated with magnetically responsive particles such as super paramagnetic iron oxide nanoparticles (SPIONs) and a curable matrix. The size, position and orientation of the magnetically responsive fibers can be controlled. The orientation of the fibers can be controlled with the application of a magnetic field and the oriented fibers can then be fixed into position by curing the polymer matrix. Multiple layers with selected configurations of fiber sizes and orientation can be formed into laminates. The range of infrared wavelengths and the range of irradiance angles can be widened with successive layers of increasingly angled fiber sections, fiber section spacing and section sizes.Type: ApplicationFiled: July 7, 2016Publication date: January 5, 2017Applicant: THE REGENTS OF THE UNIVERSITY OF CALIFORNIAInventors: Masoud Rahman, Pieter Stroeve, Ruxandra Vidu
