Preparation of Photo-Responsive Nanomicelles Loaded with Sandela 803 for Wallpaper Application

Synthetic sandela 803 are widely used for creating a clean, fresh and healthy air environment. Nanomicelles based on amphiphilic block copolymers can encapsulate sandela 803 and release their fragrance sustainably and controllably. However, incompact nanostructure and excessively sensitive controllable release limit their application. In this study, biocompatible and photo-responsive amphiphilic block copolymer PPMM10800-PEG2000 was synthesized to prepare nanomicelles for encapsulating sandela 803. The nanomicelles had dense structures due to the side chains in the hydrophobic blocks. So, the sandela 803 was hardly released in the dark. Besides, the sandela 803 could be sustainably released with slow degradation of the hydrophobic side chain in the light. Finally, these nanomicelles were applied to wallpaper to prepare the sandela 803-loaded wallpaper, and the wallpaper showed an excellent sustained and controlled released performance.
