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.

与普通胶体相比，纳米尺寸的交联聚合物网络，即直径在数十至数百纳米范围内的凝胶颗粒，由于存在大量悬垂的毛链（DHC）而具有模糊的表面。这项工作的最终目标是合成以包埋聚合物作为第二成分的纳米凝胶，并利用网络和包埋聚合物产生的 DHC 作为嵌段或接枝共聚物的类似物。为了实现这一目标，我们从各种实验研究中积累了基础数据。因此，有人建议可以制备表现出与刺激响应嵌段或接枝共聚物相似的性能的聚合物包埋的纳米凝胶颗粒。
