Abstract
Electrically conductive acrylic pressure-sensitive adhesives containing carbon black Acrylic pressure-sensitive adhesives (PSA) are non electrical conductive materials. The electrical conductivity is incorporated into acrylic self-adhesive polymer after adding electrically conductive additives like carbon black, especially nano carbon black. After an addition of electrical conductive carbon black, the main and typical properties of pressure-sensitive adhesives such as tack, peel adhesion and shear strength, are deteriorated. The investigations reveals that the acrylic pressure-sensitive adhesives basis must be synthesised with ameliorated initial performances, like high tack, excellent adhesion and very good cohesion. Currently, the electrical conductive solvent-borne acrylic PSA containing carbon black are not commercially available on the market. They are promising materials which can be applied for the manufacturing of diverse technical high performance self-adhesive products, such as broadest line of special electrically conductive sensitive tapes.
Highlights
The development in the area of electronic conductive polymers with a high electronic conductivity was awarded the Nobel Prize for Chemistry in 2000 to Alan Heegre, Alan MacDiarmid, and Hideki Shirakawa
The goal of this work was the manufacturing of electrically conductive solvent-borne acrylic pressure-sensitive adhesives (PSA) with high application performances such as high tack, high peel adhesion and excellent shear strength which can be widely applied as electrically conductive self-adhesive products, such as carrier free transfer, single sided or double side tapes on an industrial scale
The electrical conductivity of the acrylic PSA layers filled with 25 wt.% and higher concentration of Vulcan XC-72 R shows a relatively high level of 16 S/ cm
Summary
The development in the area of electronic conductive polymers with a high electronic conductivity was awarded the Nobel Prize for Chemistry in 2000 to Alan Heegre, Alan MacDiarmid, and Hideki Shirakawa. A number of synthetic routes have been developed for the preparation of conjugated polymers. The diversity has been driven by the desire to examine many different types of conjugated polymers like, polyacetylenes, polyphenylenes, polypyrroles, polythiophenes, poly (arylene vinylenes), and polyanilines and attempts to improve material properties. These six primary classes of conjugated polymers have been shown to exhibit high levels of electrical conductivity in the doped state. A number of multicomponent materials, usually polymer blends and composites have been prepared in which at least one of the components is a conducting materials[1,2,3,4]
