▎ 摘　　要

NOVELTY - Preparing nylon 66 photonic crystal fiber of protein stone structure or inverse opal structure comprises preparing opal-structured nylon 66 photonic crystal fibers by directional electrospinning technology and using electrospinning solution containing polystyrene microsphere latex and nylon 66, or preparing the nylon 66 photonic crystal fiber of the protein stone structure by a sacrificial template method to prepare the nylon 66 photonic crystal fiber of the inverse opal structure. USE - The method is useful for preparing nylon 66 photonic crystal fiber of protein stone structure or inverse opal structure used in electronic intelligent skin, catalysis, filtering and solar cell. ADVANTAGE - The fiber: has high color saturation, both excellent mechanical properties and waterproof properties, excellent shape by attaching to three-dimensional (3D) structures, and excellent application prospects in the field of textiles or intelligent electronic skin. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a nylon 66 photonic crystal fiber with protein stone structure or inverse opal structure obtained by the above mentioned method.
