摘要: The synthesis of poly-2-hydroxyethyl methacrylate inverse-opal hydrogel (IOHGPHEMA) was realized by capillary-force-induced in situ polymerization a polystyrene colloidal crystal template. created IOHGPHEMA films show brilliant blue-violet color when they are immersed deionized water and reach swelling equilibrium. stop band the can be tuned within entire visible wavelength range immersing them into different chemical solutions, such as aldehydes, ketones, amides, dimethyl sulfoxide, alcohols. extent reflective peak shift not only depends on number hydrogen donors but also chain length structure chemicals their concentration. Since have reflectance spectra structural colors response to compounds same series, this provides potential way visually detect homologues other with similar properties. This simple, yet effective, method ...
