Abstract
Cellulosic nanofibres were made from sulphite bleached softwood using mechanical action.
Fibre dimensions were evaluated with FE-SEM. The average diameter was found to be below
100 nm. Composites containing up to 50% of these cellulosic nano fibres and starch were
prepared using a wet film casting method. Three routes for preparation were evaluated for
their effect on mechanical performance of the resulting films. All resulting films were
translucent and showed an increase in strength of a factor of 1.5 larger than for conventional
flax-PP composites. The failure strain remained at the same level. Nanofibre inclusion did not
result in a significant effect on the oxygen barrier properties of starch films up to at least 30
wt.% fibre in starch. Furthermore, the sensitivity of starch to water was reduced. Barrier
properties against O2 and H2O were improved by addition of 4 wt.% of nanoclay. Nanoclay
addition up to 4 wt.% had no significant effect on the films strength, stiffness and strain at
failure
