Progress in 2D/3D nanomaterials incorporated polymer thin films for refractive index engineering: a critical review.

To develop materials with improved optical qualities and tunable refractive indices that can be utilized to control the behavior of light or electromagnetic radiations, polymer thin films have been used. High refractive index (RI) nanoparticle-incorporated polymer thin films are usually made by combining high RI inorganic nanoscale structures with a transparent, accessible polymer matrix. Hybrid nanocomposites, which combine the various benefits of inorganic and polymer components, offer a wide range of fascinating possibilities for advanced optoelectronic production and optical engineering such as advanced display device encapsulants; microlens components for complementary metal oxide semiconductor image sensors; plastic lenses for eyeglasses; camera, pick-up, and projector lenses; superior performance modules for sophisticated display devices. The development of polymers with a high refractive index (n) during the last ten years is discussed in this review, which also emphasizes the design idea to raise n values and Abbe's number (v) of polymers. The physics of predictable and controllable refractive tailored films is presently comprehended. Film applications in unconventional fields are explored. An outlook for the science and technology of such types of 2D/3D nanomaterials integrated polymer thin films concludes the review. [ABSTRACT FROM AUTHOR]
