Aromatic wallpaper was developed in order to provide fragrant atmosphere for inter space with new properties and added value. Micro-encapsulation technology is an effective method to control release of fragrance. If wallpaper is treated with micro-encapsulated fragrance, longer scent holding time is expected. This article reported the detailed preparation processes and analysis of two sorts of wallpapers with gas chromatography-mass spectrometry (GC–MS) and electronic nose (E-Nose). The morphology of blank wallpaper and the aromatic wallpaper were characterized by scanning electron microscopy (SEM). The aroma content of fragrant wallpapers was investigated by head-space solid phase-micro-extraction (SPME) and GC–MS. The employ of an electronic nose to measure the intensity of fragrant release from the wallpaper was also conducted. The release experiments indicated that aromatic wallpaper had the eminent and stable sustained release property. What’s more, the sustained release time of aroma could reach more than 3 months. Meanwhile, the aroma intensity and the comfortable degree were associated with sensory valuation to confirm which one is the best fit for human feelings.
