composite are considered to form ultra strong and stiff material by CNTs’
mechanical property. This thesis focus on the fabrication and
characterization of flexible conductor by the composite of mixing CNTs
and silver. The mixture was then printed on plastic by screen printing
method indifferent patterns. After we fabricated such conduction lines,
we measured their electrical properties to stress variations. At first, we
analyzed the resistivity of the composite by mixing different ratios of
CNT and Ag paste (by volume %). The results indicate that good
conductivity can be maintained when 50% of CNT incorporated in the
matrix. It is known that the conductive line suffered very large stress
when the flexible substrate was bent. The following experiments
performed the additional CNTs embedded in the conductive line can
provide better performance to enhance the structure stiffness, when the
substrate suffered horizontal tension and bending stresss. On the other
hand, we measured the resistivity of the metal line in the airtight space
with different temperature, the results show that good stability to
temperature by adding CNTs in the conductive line .
We also test the durable conductor by integrated CNTs in the
fabrication process which exhibited better reliability and conductivity to
the conventional flexible screen printed conductor .
