TREND: What Morphologies Do We Want? - TEM Images from Dilute Diblock Copolymer Solutions
Hong Zhao, Qianjin Chen, Liangzhi Hong, Lei Zhao, Jianfang Wang, Chi Wu*
Various exotic morphologies of block copolymers in solutions have been reported only based on TEM imaging. Do they really exist in solutions or are they just some kinetically frozen structures formed during the TEM sample preparation? Fairly speaking, more and more people realize that it is necessary to use cryo-TEM to ascertain different morphologies of block copolymers in solutions. However, when a modern cryo-TEM is not accessible, a combination of different methods, such as LLS, freeze-drying, and TEM should be used.
