“…Colloidal photonic crystals (PCs) have attracted great interest due to their special light manipulation properties [1,2], and have showed promising applications in various fields such as chemical and biological sensors [3,4], optic devices [5], coating materials [6], and catalytic supports [7]. Particularly, polymer colloidal PCs have demonstrated important applications ranging from photonic papers [8], full-color displays [9] and UV protection [10], to responsive optic devices.…”

Abstract:A facile fabrication of photonic crystals (PCs) with an eye pattern similar to peacock tail feathers has been demonstrated by self-assembly of colloidal particles in a sandwich mode. The sandwich mode is formed by superhydrophilic flat substrate sandwiching the poly(styrene-methyl methacrylate-arylic acid) (Poly(St-MMA-AA)) latex suspension (2 wt%) by the hydrophobic one. The patterns are characterized by optical microscopy images, reflection spectra, and the relative scanning electronic microscope images. This work will provide beneficial help for the understanding of the self-assembly process of colloidal crystals.

“…The swelling of NHC contribute to the red shi of the reection peak, and the swell ratio can be calculated by the reection peak change. For the NHCA, the reection obeys Bragg and Snell's law (1): 10,40…”

“…In addition, being a good solvent for many organic compounds, ethanol is ubiquitously used as solvent for many commercial pharmaceutical and healthcare products (e.g., antiseptic mouthwash and liquid medicines). However, the detrimental side effects of ethanol that greatly impede traditional fuel systems and gasoline engines (especially for aircraft fuel systems) and children health have aroused strong interest in developing inexpensive ethanol sensors for pilots and other people that need ethanol‐free products . Unfortunately, currently available ethanol sensors, which are mostly electrically operated, are usually expensive, bulky, requiring calibration, and exhibiting limited measurement range .…”

Here novel chromogenic photonic crystal sensors based on smart shape memory polymers (SMPs) comprising polyester/polyether-based urethane acrylates blended with tripropylene glycol diacrylate are reported, which exhibit nontraditional all-room-temperature shape memory (SM) effects. Stepwise recovery of the collapsed macropores with 350 nm diameter created by a "cold" programming process leads to easily perceived color changes that can be correlated with the concentrations of swelling analytes in complex, multicomponent nonswelling mixtures. High sensitivity (as low as 10 ppm) and unprecedented measurement range (from 10 ppm to 30 vol%) for analyzing ethanol in octane and gasoline have been demonstrated by leveraging colorimetric sensing in both liquid and gas phases. Proof-of-concept tests for specifically detecting ethanol in consumer medical and healthcare products have also been demonstrated. These sensors are inexpensive, reusable, durable, and readily deployable with mobile platforms for quantitative analysis. Additionally, theoretical modeling of solvent diffusion in macroporous SMPs provides fundamental insights into the mechanisms of nanoscopic SM recovery, which is a topic that has received little examination. These novel sensors are of great technological importance in a wide spectrum of applications ranging from environmental monitoring and workplace hazard identification to threat detection and process/product control in chemical, petroleum, and pharmaceutical industries.
