A Versatile Approach for the Preparation of Thermosensitive PNIPAM Core-Shell Microgels with Nanoparticle Cores

摘要

Thermosensitive microgels made of N-isopropylacrylamide (NIPAM) crosslinked with N,N-methylenebisacrylamide (BIS) are well-studied systems.Due to the change in size induced by external stimuli such as temperature,pH and ionic strength these colloidal particles belong to the group of so-called smart materials.They combine properties of classical colloids (e.g.crystallization) with the properties of a responsive polymer system.
