Abstract

Doubly polymerized ionic liquids (DPILs) have been of interest for applications in organic electronics in which achieving ”ion locking” is the goal. An understanding of chemical handles that affect the dielectric relaxation dynamics and mechanism of ion transport is lacking in DPILs. The goal of this work is to target two overarching questions: How does varying the cationic linker length in a DPIL change the mechanism of dielectric relaxation and conduction? Is there a critical amount of mobile ions that will differentiate a DPIL from simple PILs? Herein, methacrylate based DPILs that resemble the commonly studied ionic liquid, [EMIM][TFSI], are synthesized, thermally characterized using Differential Scanning Calorimetry (DSC), and dielectrically characterized using Broadband Dielectric Spectroscopy (BDS).
