![]() The performance of OMIECs for use in organic electrochemical transistors (OECTs) is benchmarked by their ability to amplify small voltage signals. At the core of OMIEC device operation is the conversion of ionic currents from an external electrolyte to modulations in the electronic carrier density of a conjugated polymer (CP) 8. These devices benefit from a combination of excellent electronic properties (hole mobilities of 1 to 10 cm 2 V −1 s −1) and high ionic conductivities (up to 10 −2 S cm −1) 7. Organic mixed ionic-electronic conductors (OMIECs) have emerged for applications in bioelectronics where their properties can be exploited for sensing 1, neural recording 2, complementary logic 3, energy harvesting 4 and storage 5, and memory 6. We show that the timescale of hole-limited doping can be controlled by the degree of microstructural heterogeneity, enabling the design of conjugated polymers with improved electrochemical performance. Using operando optical microscopy, we reveal that electrochemical doping speeds in a state-of-the-art polythiophene can be limited by poor hole transport at low doping levels, leading to substantially slower switching speeds than expected. Here, we show that this basic assumption does not hold for conjugated polymer electrodes. In semiconducting electrodes, electrochemical doping is assumed to be limited by motion of ions due to their large mass compared to electrons and/or holes. ![]() While the mixed conductors enabling these technologies are widely used, the dynamic relationship between ionic and electronic transport is generally poorly understood, hindering the rational design of new materials.

Additionally they are not subject to dual use or military defence, not subject to ITAR and are EAR 99, not subject to export control limitations. See the tape below for the range of polyimide tapes we currently offer. LINQTAPE™ PIT-Series polyimide tapes typically come in 33 meter (36 yard) length rolls of varying widths. The range of polyimide tapes we offer has grown over the years as customers requested anti-static versions of adhesives, adhesives that left no residue after removal or very thin layers of adhesive. In applications where silicone can absolutely not be used, or in applications that require a higher room-temperature adhesion is needed, CAPLINQ offers an acrylic adhesive version of polyimide tape. ![]() The base material itself has the same high-temperature resistance, and dielectric properties described above, but the adhesive type and properties play an important role in the selection process of a polyimide tape.įor high-temperature applications, silicone is the adhesive of choice for polyimide tapes because it has the highest temperature resistance and maintains its adhesion the most when exposed to higher temperatures. LINQTAPE™ PIT-Series polyimide tapes start with a LINQTAPE polyimide film base and then an adhesive layer is applied to it. High-Temperature Resistant Polyimide Tape ![]()
