High conductivity textile printing water-like inks

In this study, the water-like dispersion of conductive carbon black was converted into refined oil ink.
when high conductivity is required, inks are preferably made of metal nanoparticles such as silver. However, such inks are expensive and it is often not known that textiles often undergo severe washing and wear during end-use

.
In this study, this is part of a larger study conducted by the authors, converting water-based dispersions of conductive carbon black into refined inks, which are then washed and creased to determine their durability. The researchers found that although the final pigment load in all the preparations was significantly lower than the usual pigment load in commercial conductive agents, the ink was not only stable but also highly conductive when combined with different adhesives. Ink.
the conductivity of the formulated inks was significantly higher
in addition, it was found that the conductivity of the formulated inks after washing and indentation testing was significantly greater than that of the commercially conductive inks tested. This indicates that the use of large surface areas in textile printing inks and a relatively small amount of high conductive carbon black pigments are conducive to obtaining some of the key desired properties, especially those related to the durability of the ink film.
