Viscosity of conductive inks with m-VROC® and microVISC™:

Viscosity of conductive inks, paints and coatings is key to establish manufacturing processes for printed electronics and display systems. The complexity of printing and coating technologies has motivated a rapid growth of the conductive inks industry. To meet the market demands, efficient, highly accurate and fast characterization methods are required.
Conventional viscometers are often unable to fully characterize complex fluids (i.e. they are not able to measure viscosity as a function of shear rate or extensional properties). On the other hand, rheometers are limited to relatively low (<10,000 1/s) deformation rates. Our microfluidic-based VROC® (Viscometer/Rheometer On a Chip) technology overcomes these limitations.
RheoSense viscometers are able to fully characterize the flow curves (viscosity vs shear rate) of complex fluids for shear rates ranging from 0.5 to 1,400,000 1/s. Additionally, we offer measurements of extensional viscosity and temperature control from 4°C to 105°C. Accurate measurements of shear and extensional viscosity at the deformation rates and temperatures relevant for the fabrication processes are essential to understand the subtleties of the different printing and coating technologies.

VROC® powered instruments, provide a solution to the challenges of conventional technologies. The high accuracy and repeatability over a wide range of deformation rates make our systems Simply Precise™ at a fraction of the sample volume and testing time!
