在这项工作中，研究了自组装氨基酸附加的苝酰亚胺（pbi）在加工成薄膜时，其电阻率随弯曲的变化而变化。pbi在水中组装成结构，干燥后形成薄膜。这些通常脆弱的薄膜可以耐受弯曲，这取决于它们形成的聚集体。此外，薄膜在这种机械刺激下可逆地改变其电阻率。这种变化与薄膜的弯曲程度成正比，这使得它们有可能被用于定量测量机械运动，比如在可穿戴设备中。探讨三种不同的苝酰亚胺结构在溶液中的自组装对干燥薄膜的最终性能的影响。这些结构在剪切和磁场作用下排列整齐。研究发现，它们如何干燥成膜对它们在柔性导电材料中的使用有重要影响，并且证明了这种电阻率如何与它们弯曲的角度成正比。
In this work, self‐assembled amino‐acid appended perylene bisimides (PBIs) have been studied that when processed into thin films change their resistivity in response to being bent. The PBIs assemble into structures in water and form thin films upon drying. These normally delicate thin films can be tolerant to bending, depending on the aggregates they form. Furthermore, the films then reversibly change their resistivity in response to this mechanical stimulus. This change is proportional to the degree of bending of the film giving them the potential to be used quantitatively to measure mechanical movement, such as in wearable devices. Exploring how the self‐assembly of three different perylene bisimide structures in solution has an effect on the final properties of a dried thin film. These structures were characterized by aligning under shear and under a magnetic field. It was found that how they dry into a film has a major effect on their use in flexible conductive materials and it was demonstrated how this resistivity is proportional to the angle they are being bent at.
