Applicant: Fudan University

Patent No.: ZL 200910194629.3

Abstract：

The invention belongs to the field of organic functional polymer materials, and relates to an amphiphilic block copolymer with a light responsiveness group and a temperature responsiveness group as well as a preparation method and application thereof in forming stimulus-response aggregates in solution. The amphiphilic block copolymer is prepared by using the method of atom transfer radical polymerization (ATRP), and can be used for forming nanoscale aggregate materials in solution. The nanoscale aggregate materials are characterized in that the sizes of the aggregates are in nanoscale, and the aggregates are distributed uniformly and can be adjusted and controlled through light and temperature; and the controllable release of substances coated with the materials can be realized under the control of light, or temperature, or light and temperature. The nanoscale controllable release carrier material provided in the invention can widely be applied to the fields such as biomedical science, chemical catalysis and synthesis, sensor technology, and the like.
