摘　　要：The thermosensitive micellization of dextran-g-PNIPAAm in aqueous solutions has been investigated by fluorescence spectroscopy, dynamic light scattering and transmission electron microscope. The formed polymeric micelles showed different diameters of about 20 nm or 100 nm, when the solution temperature was below or above the phase transition temperature.

关 键 词：Amphiphiles micelles poly（N-isopropylacrylamide） thermosensitive copolymers.
