Embodiment 1

[0064] At a temperature of 20° C., an aqueous emulsion containing temperature-responsive monodisperse poly-N-isopropylacrylamide latex particles (with a particle diameter of 250 nm) at a concentration of 20 wt % was placed in an ink cartridge of an inkjet printer. After printing and drying on the glass substrate by an inkjet printer, the monodisperse poly-N-isopropylacrylamide latex particles form a periodically arranged three-dimensional colloidal photonic crystal film on the glass surface, which consists of responsive monodisperse poly(N-isopropylacrylamide) latex particles. N-isopropylacrylamide latex particles are stacked, with temperature responsiveness and computer-designed patterns. The band gap of the patterned photonic crystal is 610nm. As the temperature changes from 10°C to 40°C, its photonic bandgap will change from 610nm to 370nm, and the photonic bandgap will have a blue shift of 240nm.

[0065] When the particle diameters of the monodisperse poly N-isopropylacry...

Embodiment 2

[0068] At a temperature of 30° C., an aqueous emulsion containing humidity-responsive monodisperse polyacrylamide latex particles (with a particle size of 200 nm) at a concentration of 15 wt % was placed in an ink cartridge of an inkjet printer. After printing and drying on the polyethylene film substrate by an inkjet printer, the monodisperse polyacrylamide latex particles form a periodically arranged three-dimensional colloidal photonic crystal film on the surface of the polyethylene film, which is composed of monodisperse polyacrylamide latex Beads are stacked, with humidity responsiveness and computer-designed patterns. The bandgap of patterned photonic crystal is 430nm, and its photonic bandgap will change from 400nm to 580nm as the humidity changes from 20% to 100%, and the photonic bandgap has a red shift of 180nm.

[0069] When the particle diameters of the monodisperse polyacrylamide latex particles used are 100nm, 300nm, and 400nm, the photonic bandgaps of the prepar...

Embodiment 3

[0072] At a temperature of 40° C., an aqueous emulsion containing pH-responsive monodisperse polyacrylic acid latex particles (with a particle size of 300 nm) at a concentration of 5 wt % was placed in an ink cartridge of an inkjet printer. After printing and drying on the polypropylene film substrate by an inkjet printer, the monodisperse polyacrylic acid latex particles form a periodically arranged three-dimensional colloidal photonic crystal film on the surface of the polypropylene film, which is stacked by monodisperse polyacrylic acid latex particles made with pH responsiveness and computer-designed patterns. The band gap of the patterned photonic crystal is 700nm. As the pH value changes from 3 to 13, its photonic band gap will change from 400nm to 920nm, and the photonic band gap will have a red shift of 520nm.

[0073] When the particle diameters of monodisperse polyacrylic acid latex particles are 100nm, 200nm, and 400nm, the photonic bandgaps of the prepared films ar...

Abstract

The invention relates to a method for preparing patterned colloid photon crystalline membrane with responsiveness by using inkjet printing technology, and the prepared membrane and the application of the membrane. By the combination of an inkjet printer and a computer, and design of patterns by the computer software, the patterned colloid photon crystalline membrane with responsiveness in the invention is prepared by assembling the monodisperse latex particles of responsiveness printed by the inkjet printer or assembling the monodisperse latex particles printed by the inkjet printer and a responsiveness function system. The preparing method has the characteristics of simple technology, low cost and no special requirements to equipment. The photon band gap of the patterned colloid photon crystalline membrane can realize the changes of the ultraviolet zone, the visual light zone and the infrared zone with the excitation of external side. The patterned colloid photon crystalline membrane obtained by the method in the invention can monitor the changes of external environment, and has wide application prospects in fields of sense, detection and the like.

Description

technical field [0001] The invention belongs to the technical field of preparation and application of colloidal photonic crystal films, and in particular relates to a method for simply and rapidly preparing responsive and patterned colloidal photonic crystal films by inkjet printing technology, and the prepared films and potential applications of the films. Background technique [0002] Since the concept of photonic crystals was proposed in 1987, after more than 20 years of development, it has become a research hotspot of common concern in the fields of physics, optoelectronics, materials science, chemistry, and nanotechnology. Based on the various special properties of known photonic crystals, its application fields cover many fields such as light, electricity, catalysis, sensing, display, and detection. In the usual patent literature, colloidal photonic crystal films are mainly used in filters (such as CN: 01105105.1, CN: 98110990.X), optical switches (CN: 02160207.7), opt...
