首次用激光扫描共聚焦显微镜(LSCM)观察了半透明聚(N-异丙基丙烯酰胺)凝胶的内部结构。观察到的图像反映了凝胶中的介观内部结构，这是由于文本中描述的网络聚合物的“固定浓度波动”。由激光共聚焦显微镜拍摄的一系列横截面图像构建的凝胶的三维内部结构表明，凝胶具有双连续的结构域结构，由聚合物网络中致密和稀疏的区域组成。
Internal structures of translucent poly(N-isopropylacrylamide) gel were for the first time observed by laser scanning confocal microscopy (LSCM). The observed image reflected the mesoscopic internal structures in the gel due to the "fixed concentration fluctuations" of network polymers as described in the text. Three-dimensional internal structures in the gel constructed from a series of the cross section images taken by the LSCM revealed that the gel had a bicontinuous domain structure consisting of regions dense and sparse in polymer networks.
