Improving the electrical and mechanical behavior of electrically conductive paint by partial replacement of silver by carbon black

Abstract

Partial replacement of silver particles by carbon black (low cost) in electrically conductive paint was found to decrease the electrical resistivity and increase the scratch resistance of the resulting thick film, which is for use in electrical interconnections. An effective carbon black content is 0.055 of the total filler volume. By using atotal solid volume fraction of 0.1969 and asilane-propanol (1:1 by weight) solution as the vehicle, ap aint that gives at hick film with resistivity 2×1 0 −3 ⍀ ·cm has been attained.

The Internet-of-Things: Review and research directions

“…Even old things could be potentially connected. Surfaces could be coated with conductive paint (e.g., Leong & Chung, 2006); electronic polymers now allow for smart glass as the surface for mirrors (MacDiarmid, 2001;Carpi & De Rossi, 2005); plastic electronics enable circuits to be produced at relatively low cost by printing electronic materials onto any surface, whether rigid or flexible (Kaltenbrunner, Sekitani, Reeder, Yokota, Kuribara, Tokuhara, Drack, Schwödiauer, Graz, Bauer-Gogonea, & Bauer, 2013).…”

Investigation of the Performance of ATH Powders in Organic Powder Coatings

“…Fillers are normally inorganic minerals that are chemically inert and produced artificially or naturally. The addition of fillers serves two purposes: the first is to reduce the content of the polymer resin which is the most expensive part of the formulation since they are derived from petroleum; the second is to modify certain mechanical properties of the coating [6][7][8][9][10].…”
