Polymer nanostructures can be designed with specific properties and functions, such as controlled shape, size, chemical composition, and adaptive ability to change shape or size in response to environmental cues. Precise control to organize polymer chains into uniform nonspherical symmetric and asymmetric nanostructures and at scale remains a synthetic challenge. Here, by using the temperature-directed morphology transformation (TDMT) method we show through a systematic organization of polymer chains the synthesis of well-defined asymmetric (i.e., tadpole) and symmetric (i.e., worm) nanostructures in water at high polymer concentrations. This method further allowed the production of tadpoles with controlled and uniform tail lengths, ranging from 200 to 800 nm. The organization of chains could be driven by environmental conditions to produce adaptive nanostructure systems.

通过定向链组织的均匀对称和不对称聚合物纳米结构

可以设计具有特定特性和功能的聚合物纳米结构，例如受控的形状，尺寸，化学成分以及根据环境提示改变形状或尺寸的自适应能力。精确控制以将聚合物链组织成均匀的非球形对称和不对称纳米结构，仍然是一个综合性挑战。在这里，通过使用温度定向形态变换（TDMT）方法，我们通过聚合物链的系统组织显示了在高聚合物浓度下水中定义明确的不对称（即t）和对称（即蠕虫）纳米结构的合成。该方法还允许生产具有受控且均匀的尾长范围为200至800 nm的of。
