The broader impact/commercial impact of this project is centered on its ability to significantly enhance the conductive ink applications in the printed electronics market. Printed electronics is dominated by high viscosity silver pastes for screen-printing applications. However, these pastes are extremely high cost, require high annealing temperatures, and do not achieve the high conductivities with its metal content. Electroninks? particle-free silver pastes open the possibility of using of a low silver weight percentage paste that can achieve high conductivities at low temperatures enabling a range of new applications in printed electronics. This Small Business Innovative Research (SBIR) Phase I project will focus on optimizing novel silver ink formulations that have a low weight percentage of silver (10-20%) that achieve much higher conductivity (50-90% of bulk silver) than current silver pastes (5-10% of bulk silver) at temperatures that are compatible with low-cost substrates (150ºC). Electroninks will focus on novel silver precursor chemistries that allow full gelation of otherwise low-viscosity inks for screen-printing applications.

该项目的更广泛的影响/商业影响集中在其显著增强导电油墨在印刷电子市场的应用的能力。印刷电子产品主要是用于丝网印刷应用的高粘度银浆。然而，这些浆料的成本极高，需要较高的退火温度，而且其金属含量不能达到高电导率。电子墨水？无微粒银浆使人们有可能使用低银重量百分比的浆料，这种浆料可以在低温下实现高电导率，从而在印刷电子产品中实现一系列新的应用。这个小型企业创新研究(SBIR)第一阶段项目将专注于优化新型银墨配方，这些配方含有低重量百分比的银(10-20%)，在与低成本基材(150°C)兼容的温度下，具有比目前的银浆(体积银的5-10%)高得多的导电性(50%-90%的散装银)。电子油墨将专注于新的银前驱体化学物质，使丝网印刷应用中的其他低粘度油墨完全凝胶化。
