Abstract：The rapid magnetic chromogenic photonic crystal film with thermal polymerization method was prepared by embedding glycol (EG) droplet containing Fe3O4@PAA photonic nanochains into polydimethylsiloxano (PDMS) matrix.FT-IR,SEM,optical microscope and fiber optical spectrum were adopted to characterize and analysis the obtained product.The results indicate that nanochains in the droplet can orientate along the direction of magnetic field which endow the photonic crystal film brightness tunable property.The obtained photonic crystal film has excellent optical performance under 100 Gs when the chain length of nanochains is 5 μm and mass concentration is 1.77 mg/mL and the reflection spectrum of photonic crystal film can reach saturation within 2 seconds,which show rapid magnetic chromogenic properties.
