In this paper, polyethylene glycol thioglycolate was prepared by esterfication. Spherical silver nanoparticles were formed from silver nitrate solution by liquid chemical reduction method with hydrazine hydrate as reducant. Based on the previous two steps, the nanoAg was absorbed by the polyethylene glycol thioglycolate trough the deposition. Metal nanoparticles were absorbed by polyethylene glycol thioglycolate with M-S bond to form polymer modified nanoparticle powder. The conductive inks were prepared using modified nanoparticles, other filler and laborator self-made water-borne polyurethane resin as the bonding material. Then the ink was coated on the PET film surface to mold. Catalyst, temperature and time effected esterfication. The esterfication rate was about 55% at 110°C for 3 hours. XRD indicated that the nanoAg prepared were cubic crystals, TEM showed that the size of modified nanoAg was less than 10nm. Metal nanoparticles with M-S bond effectively reduced the surface energy and had better compatibility with organic materials. Cross-cutting tests showed that adhesion between the ink and PET films was well and the conductive inks also showed good wet resistance and thermostability.

ABSTRACTWe proposed the use of Copper (Cu) and Zinc (Zn) nanoparticles as the electrodes for thin-film microbatteries in the applications of micro-scale sensors. Compared to the widely used lithium-based batteries, Cu and Zn nanoparticles are less expensive, less prone to oxidation (thus involving simpler fabrication steps) and flammability, safe to use, and only requires very simple fabrication processes.Even though the voltage output is inherently smaller (∼1V) than conventional lithium-based batteries, it is sufficient for low-voltage Integrated Circuits (IC) technologies such as 130 nm and 90 nm channel length transistor processes.Commercial paper will be used as the separator to demonstrate the battery capacity. Paper that acts as the separator is slurry-casted with nanoparticles (30-40 nm in size) on both sides. The thickness of the metal nanoparticles-coated thin films and the paper separator are 1 μm and 100 μm, respectively.The electrodes were developed to achieve high conductivity (lower than 1 (Ω·cm)-1) with smooth surface, good adhesion, and flexibility. The metal nanoparticles will be formulated to slurry solutions for screen printing or ink-jet printing for the battery fabrication. For fabrication purposes, the slurries viscosity is approximately in the range of 10-12 cPs at the operating temperature, a surface tension between 28-33 dynes/cm. During the fabrication process including printing/coating and sintering, reductive environment is required to minimize the oxidation. AFM (Atomic Force Microscopy) and EDS (Energy Dispersive Spectroscopy) results will be employed to demonstrate the surface morphology as well as the percentages of metal oxides. Batteries will be tested with and without an ionic liquid for comparison. Humidity effects on the battery performance will also be discussed.Different geometries that are designed to make the batteries with higher voltage or charge will be proposed. Characterization results will include the open-circuit voltage, dielectric property, charging and discharging curve, capacitance and capacity, AFM of the surface test, EDS of the electrodes and the SEM (Scanning Electron microscopy) of the particles.Ourresearch suggest that conductive paper can be scalable and could make high-performance energy storage and conversion devices at low cost and would bring new opportunities for advanced applications.
