采用细乳液聚合法制备了载百合醛的聚丙烯酸酯纳米胶囊。然后，将PNL直接施加到皮革上。考察了表面活性剂、百合醛的用量以及搅拌速度对PNL平均粒径和载香量的影响。采用动态光散射（DLS）、透射电子显微镜（TEM）、傅里叶变换红外（FTIR）光谱和热重分析（TGA）等方法对PNL的微观结构进行了表征。采用扫描电镜（SEM）和气相色谱-火焰离子化检测器（GC-FID）对PNL涂饰后皮革的缓释性能进行了表征。DLS显示PNL的平均尺寸为67.78 nm，多分散指数为0.076。TEM表明球形PNL的尺寸在30-80 nm范围内变化。红外光谱表明百合醛被包裹在聚丙烯酸酯纳米胶囊中。热重分析表明，纳米胶囊的载香率达到36.83%。SEM和GC-FID分析表明，经PNL整理的皮革的耐屈挠性优于经百合花乳液整理的皮革。© 2013 Wiley Periodicals，Inc.

Polyacrylate nanocapsules loaded with lilial (PNLs) were prepared via miniemulsion polymerization. Then, the PNLs were applied directly to leather. The influence of the contents of the surfactant and lilial and the stirring speed on the mean size and fragrance loading capacity of the PNLs was investigated in detail. The microstructure of the PNLs was determined by dynamic light scattering (DLS), transmission electron nicroscopy (TEM), Fourier transform infrared (FTIR) spectrometry, and thermogravimetric analysis (TGA). The sustained release properties of the leather finished by PNLs were characterized by scanning electron microscopy (SEM) and gas chromatography with a flame ionization detector (GC-FID). DLS showed that the mean size of the PNLs was 67.78 nm, and the polydispersity index was 0.076. TEM illustrated that the size of the spherical PNL varied in the range 30–80 nm. FTIR spectroscopy showed that lilial was encapsulated into the polyacrylate nanocapsules. TGA illustrated that the fragrance loading ratio of the nanocapsules reached 36.83%. SEM and GC-FID indicated that the leather finished by the PNLs had better flexing endurance than that finished by lilial emulsion. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2014, 131, 40182.
