Abstract
The effect of chemo-enzymatic hydrophobisation of spruce
chemi thermo mechanical pulp, CTMP, on the properties of
biocomposites was studied. CTMP surface was modified with
tailor-made phenolic compounds with different alkyl chain
length substituents suited to physical properties of
plastic. Dispersion technology was developed and applied
for dosing these water insoluble substrates. The modified
fibre materials were compounded with polylactic acid
(PLA) or polyhydroxybutyrate (PHB) and the properties of
composites were studied. Modification with dodecyl
gallate (DOGA) resulted in improved dispersion of fibres
both with PLA and PHB. In addition, mechanical properties
were found to be similar or better than with reference
fibre containing materials, but depending on the
biopolymer type and its' melt behaviour. The enhancement
to mechanical properties was found to be more significant
in biocomposites in which PLA was used as matrix polymer.
