Research Abstract

Nano-sized cross-linked polymer networks, i.e., gel partcles with diameters in the range of tens to hundreds of nanometers, have an obscure surface due to a lot of dangling hair chains (DHC), in contrast to usual colloids. The final goal of this work is to synthesize nanogels with entrapped polymers as the second constituent and to utilize the DHCs resulting from the network and entrapped polymers as the analog of block or graft copolymers. To achieve this goal we accumulated fundamental data from various experimental studies. As a result, it has been suggested that polymer-entrapped nanogel particles exhibiting performance similar to stimuli-responsive block or graft copolymers would be prepared.
