Influence of biopolymer and the polyol newtonian fluid on properties of extrusion inks of carbon
nanotubes

xtrusion printing inks were prepared with multiwall carbon
nanotube (MWNT) and iota-carrageenan (IC), a biopolymer
thickening agent containing two sulphated groups, extracted
from red seaweeds andwith glycerine, a polyol newtonian fluid.
After adjusting for the proper viscosity of both the inks i.e. IC-
MWNT and G-MWNT, they were extruded by a syringe printer
on glass slide, IC gel films and PET transparent sheet. Conductive
tracks of the deposited printed inks were characterized with
microscope, SEM, profilometer, contact angle measurement
and conductivity determination. Conductivity of IC-MWNT track
was 9±1 S/m and that of G-MWNT was 2942±84 S/m on glass
substrate of one layer thick. This is because a smaller number
of CNT is present in G-MWNT track as confirmed by SEM study.
Profilometry showed that increased number of extruded layers
gave increased cross-sectional area. SEM study showed that
printing ink is embedded into surface of IC film, discontinuous
on glass slide and smoother on PET sheet
