| description | The invention belongs to the technical field of high polymer materials, and discloses a pH and temperature dual stimuli-responsive structural color film and a preparation method and application thereof in optical anti-counterfeiting. The method comprises the following steps: by utilizing an improved method, under the catalytic action of ammonia water, adjusting various factors to prepare monodisperse silicon dioxide colloidal crystal microspheres with different particle sizes; the preparation method comprises the following steps: adding hydroxyethyl methylacrylate, a polymer monomer A and a polymer monomer B into an initiator and a cross-linking agent by utilizing a sacrifice template method, uniformly mixing to obtain a pre-polymerized solution, filling a photonic crystal template with the pre-polymerized solution, carrying out illumination induced polymerization, and removing the template to obtain the pH and temperature dual-stimulation response structural color film. The obtained film material can be used |
