Abstract Biologically and environmentally resorbable electronic devices support application possibilities that cannot be addressed with conventional technologies. This paper presents highly conductive, water-soluble composites that can be printed to form contacts, interconnects, antennas, and other important features that are essential to nearly all systems of this type. An optimized material formulation involves in situ polymerization to yield a polyanhydride containing a dispersion of molybdenum microparticles at appropriate concentrations. Comparisons of essential physical and electrical properties of these materials to those of composites formed with other polymers and other metal microparticles reveal the relevant considerations. Various functional demonstrations of screen-printed test structures and devices illustrate the suitability of these conductive inks for use in water-soluble electronic devices. A key advantage of the material introduced here compared to alternatives is its ability to maintain conductance over significant periods of time while immersed in relevant aqueous solutions. Studies involving live animal models establish the biocompatibility.

金属微粒——聚合物复合材料作为可印刷、生物/可吸收导电油墨

摘要 生物和环境可吸收电子设备支持传统技术无法解决的应用可能性。本文介绍了高导电性、水溶性复合材料，这些复合材料可以印刷以形成触点、互连、天线和其他几乎所有此类系统都必不可少的重要特征。优化的材料配方涉及原位聚合以产生含有适当浓度的钼微粒分散体的聚酐。将这些材料的基本物理和电学性能与其他聚合物和其他金属微粒形成的复合材料进行比较，揭示了相关的考虑因素。丝网印刷测试结构和设备的各种功能演示说明了这些导电油墨在水溶性电子设备中的适用性。与替代品相比，这里介绍的材料的一个关键优势是它能够在浸入相关水溶液中的很长一段时间内保持电导。涉及活体动物模型的研究建立了生物相容性。
