Title: METHOD FOR DISPERSION AND IMMOBILIZATION OF FINE PARTICLES
Abstract:
Provided is a method for dispersion and immobilization of fine particles, in which a freeze-drying method capable of providing a higher dispersion stability is used. The method comprises: a freezing step in which a suspension is dripped onto a cooling substrate to form and freeze a thin film; and a drying step in which the thin film is subjected to vacuuming and dried. The method is characterized by adding a polyhydric alcohol to the suspension to lower the vapor pressure and thereby cause drying.
