Silver nanoparticles were synthesized using varied mixtures of PAA as the capping agent. Humectant, a viscosifying agent, was added to achieve an ink-like rheology. TEM images were used to determine the size distribution of the nanoparticles at multiple stages of synthesis to explore the relationship between the nanoparticle morphology and electrical properties. Ink samples were doctor-bladed onto a glass substrate and annealed at various temperatures for three hours. The resistivity of each ink sample was measured as a function of annealing time, temperature, and mechanical stress. The resistance was measured at multiple time points using a four-point probe connected to a constant-current generator. Additionally, ink was applied to flexible substrates to measure the resistivity as a function of mechanical stretching. <br/><br/>
