氰基聚合物光子晶体薄膜的制备及其稳定性.

Polymeric photonic crystals with sensitive functional groups such as carboxyl, hydroxyl and ester have been widely used in the field of sensing. While achieving high sensitivity for small organic and biomolecule detection, these sensors are also susceptible to complex environmental factors, such as organic solvents, acid-base and ionic strength. Different from using other materials to fill or encapsulate to stabilize the structure of photonic crystals, this work fabricated a flexible inverse opal photonic crystals with high stability based on the chemical inertness and stability of cyanide group, and explored their acid and alkali resistance, organic solvent resistance and high temperature resistance. The results show that this kind of cyano-based thin films overcome the limitations that the polymeric photonic crystals were easy to be damaged and affected by the detection environment. They would provide a good theoretical and experimental basis for the further development and application of photonic crystals in the field of sensing. [ABSTRACT FROM AUTHOR]
