Transparent flexible fluorescent films based on natural rubber composited with quantum dots for traffic equipment

Abstract

Abstract Quantum dots are one of the nanotechnology materials applied in various ways like flexible electronic devices and others. In this work, we study and synthesize semiconductor quantum dots (SQDs) to produce fluorescent natural rubber films by the technique called directed blending. We illustrate the appropriate ratio of mixtures employed in our method such as quantum dot colloidal solutions and natural latex as well as moles between each substance. During the process, the liquid composite and rubber adhesive is applied to the surface for creating flexible fluorescent films that can be dried at room temperature. In addition, these flexible fluorescent films can be covered with diverse curved surfaces applied probably as a traffic device like luminous traffic cones or traffic signs that glow at night. Based on the unique properties of our products, our research provides an application developed from quantum dot nanotechnology.
