Abstract
Cellulose nano- and microfibrils (CNF/CMF) grades vary
significantly based on the raw materials and process
treatments used. In this study four different CNF/CMF
grades were combined with kaolin clay pigment particles
to form nanoporous composites. The attained composite
properties like porosity, surface smoothness, mechanical
properties and density properties depended strongly on
the raw materials used. In general, higher kaolin content
(~80 wt%) led to controllable shrinkage during drying,
which resulted in improved dimensional stability of
composites, compared to a lower kaolin content (~50 wt%).
On the other hand, the use of a plasticizer and a high
amount of CNF/CMF was essential to produce adequate
elasticity for the composites. The performance of
transistors when fabricated on the nanoporous composites
was strongly dependent on the raw materials used. The
formation of the semiconductor layer was affected by the
porosity, roughness, hydrophobicity, polarity and
absorption properties of the top-most layer at the
composite. The developed natural fiber-based substrates
may be applied to novel value-added applications in
intelligent products, such as sensors and simple
displays.
