Monodispersed quinacridone nanocrystals prepared by a high-temperature and high-pressure liquid crystallization method.
Monodispersed quinacridone nanocrystals were fabricated by a high-temperature and high-pressure liquid crystallization method, which proved to be an advanced technique for fabricating nanocrystals of pigment compound. The aqueous dispersion liquid of quinacridone nanocrystals was very stable. The nanocrystats had a spherical shape with an average size of 60 nm when water was used as the high-temperature and high-pressure liquid at 260 degrees C and cooling solvent. The crystal structure of the nanocrystals could be controlled by varying the experimental conditions.
