| dc.description.abstract | Graphene is one of conductive material that has been studied widely other than silver in
the printed electronics industry. This material is considered as “wonder material” which
has excellent properties in conducting electricity. Due to these properties advantageous of
graphene, a new research study had been conducted regarding the electrical and
mechanical properties of Graphene Nanoplatelets (GNPs) conductive ink in various print
patterns. The way properties of graphene affecting the current flow of ink had become one
of the objectives of this study with respect to hardness and sheet resistivity ink. On the
other hand, this study aimed to determine the most excellent pattern and width that good
in conducting electicity. Based on the existing formulation of graphene-based conductive
ink, this study combined three different materials which are Graphene Nanoplatelets as a
filler, epoxy resin as a binder, and polytheramine as a hardener. Samples of the ink were
patterned into four (4) different types, which are a straight-line, zigzag, sinusoidal, and
square pattern, and three (3) different widths, which are 1 mm, 2 mm, and 3 mm. In this
study, to achieve the objectives, two tests were conducted, which are the sheet resistivity
test by using a four-point probe and hardness test by using a nanoindenter. At the end of
this study, sample of ink that have low sheet resistivity and high hardness has good
properties among others samples and vice versa. Besides that, the best pattern that had
the high performance of graphene was determined and discussed. The findings of this
study will be used in the future and be very helpful in improving the performance of the
existing conductive ink, which can efficiently conduct electricity at a low cost of
production. | en_US |
