The flexible, strong, and tough white-light-emitting (WLE) hybrid films are highly demanded in large-scale displays, including TV sets, monitors, and electronic interactive devices. In this work, a kind of WLE hybrid film was fabricated from hyperbranched poly(amido amine) (HPAMAM) and nanoclay with the incorporation of riboflavin (VB2) and rhodamine B (RhB). The fluorescence emission of HPAMAM was partially absorbed and effectively transferred into green and red color, which combined into a bright white light with the residue blue fluorescence. Due to the alignment of nanoclay inside the HPAMAM matrix, in addition to the strong interaction among the HPAMAM molecules and that between HPAMAM and nanoclay, this hybrid film shows to be strong and tough. The mechanical strength is about 20 MPa and the elongation is about 30%. It is convinced that this hybrid film is promising in flexible large-scale displays.
