Planar and Three-Dimensional Printing of Conductive Inks
Printed electronics rely on low-cost, large-area fabrication routes to create flexible or multidimensional electronic, optoelectronic, and biomedical devices. In this paper, we focus on one- (1D), two- (2D), and three-dimensional (3D) printing of conductive metallic inks in the form of flexible, stretchable, and spanning microelectrodes. Direct-write assembly is a 1-to-3D printing technique tha...
متن کاملMicrofluidization of Graphite and Formulation of Graphene-Based Conductive Inks
We report the exfoliation of graphite in aqueous solutions under high shear rate [∼ 108 s-1] turbulent flow conditions, with a 100% exfoliation yield. The material is stabilized without centrifugation at concentrations up to 100 g/L using carboxymethylcellulose sodium salt to formulate conductive printable inks. The sheet resistance of blade coated films is below ∼2Ω/□. This is a simple and sca...
متن کاملElectrical Interconnection by Means of Conductive Adhesives and Inks
The research aims at developing electrical interconnection technologies for the microelectronics industry. On the one hand, a substrate is needed with a conductive pattern. Currently, this is mostly done by an etching technology, which means a lot of expensive metal is wasted. In this sense an additive alternative would be attractive, which is why I’m looking into the possibilities of printing ...
متن کاملScreen Printing of Highly Loaded Silver Inks on Plastic Substrates Using Silicon Stencils.
Screen printing is a potential technique for mass-production of printed electronics; however, improvement in printing resolution is needed for high integration and performance. In this study, screen printing of highly loaded silver ink (77 wt %) on polyimide films is studied using fine-scale silicon stencils with openings ranging from 5 to 50 μm wide. This approach enables printing of high-reso...
متن کاملReversible shear gelation of polymer–clay dispersions
Reversible, shear-induced gelation of semi-dilute aqueous colloidal dispersions consisting of monodisperse discoid particles (Laponite) and weakly adsorbing polymer (polyethylene oxide) is studied through a combination of small angle neutron scattering and oscillatory shear. When shaken the samples undergo a dramatic transition from a low viscosity fluid to a self-supporting, turbid gel. This c...
