摘要：
The apparent size increase of poly(N-isopropyl acrylamide) ( PNIPAM)-based polymericmicelles upon heating was usually ascribed to their volume growth or aggregation in aqueous solution. Herein we designed a photo-cross-linkable PNIPAM-based copolymer and proposed another thermo-responsive behaviour - fusion, which is disclosed by transmission electron microscopy (TEM) after in situ fixing morphologies at desired temperatures.
