With rapid advances in flexible electronics, transparent conductive electrodes (TCEs) have also been significantly developed based on conventional indium tin oxide (ITO)-based material systems that exhibit low mechanical flexibility. Here, we exploited ITO-platform incorporated a transparent molecular adhesive, 4-aminopyridine (4-AP), to improve mechanical flexibility remarkably. The 4-AP barely affected optical transmittance and sheet resistance, it improved interfacial adhesion between the substrate and ITO. Under various mechanical tests, ITO/4-AP/poly(ethylene terephthalate) (PET) exhibited improved mechanical flexibility compared to ITO/PET. Furthermore, ITO/4-AP/PET was utilized for a flexible Joule heater having spatial uniform heat generation, voltage-dependent temperature control, and mechanical flexibility under repeated bending tests. This molecular adhesive could overcome the current limitations of material systems for flexible electronics. |
