Complex 3D geometry and high conductivity have generally been mutually exclusive characteristics for conducting polymers. For instance, poly(3,4-ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), a benchmark polymer, typically exhibits 1 to 2 orders of magnitude lower in 3D-printed forms compared 2D-processed thin films, due its sensitivity processing conditions. Here, we investigate the main causes this reduced conductivity, which are found be (1) ink formulation strategy (2)...
Rationally designed, 3D-printed architectures can effectively decouple the mechanical and electrical properties of conducting polymer hydrogels.
The conductivity and charge transport mobility of conjugated polymers (CPs) are largely correlated with their degree crystallinity, rendering the crystallization CPs an important endeavour. However, such tasks can be challenging, especially in absence sidechain functionalization. In this study, we demonstrate that incorporation a small amount oligomers, specifically tetraaniline, induce parent polymer, polyaniline, through single-step self-assembly process. resulting crystals compositionally...
Abstract Materials are more easily damaged during accidents that involve rapid deformation. Here, a design strategy is described for electronic materials comprised of conducting polymers defies this orthodox property, making their extensibility and toughness dynamically adaptive to deformation rates. This counterintuitive property achieved through morphology interconnected nanoscopic core–shell micelles, where the chemical interactions stronger within shells than cores. As result,...
A direct template based on vertically oriented tetraaniline provides a new, general route towards nanopillar and nanotube arrays for wide variety of materials. The can also be patterned at micron-resolution.
