abstract = "Biocomposites are materials that are composed of a matrix and fillers both of which derived from
renewable resources. They offer an alternative to traditional petroleum-based composites and
have gained interest due to potential environmental benefits and sustaina
idea, itaconic and succinic acids and propylene glycol were used in the synthesis of a biobased
unsaturated polyester, diluted with biobased reactive diluent, dimethyl itaconate, to cure fully
biobased unsaturated polyester resin (UPR). Despite having a low environmental impact, the
mechanical properties of biobased UPRs are not considered commercially viable compared to
their petroleum-based counterparts. To lessen the discrepancy between the two, nanocellulose
(NC) was incorporated into the biobased UPR in two ways. Firstly, NC was added during synthesis,
while secondly it was added after the synthesis of UPR was completed. Both series implied the
use of three different quan s of NC (1, 2, 3 wt.%). FTIR spectroscopy, gel content analysis,
SEM, dynamic mechanical analysis, and uniaxial tensile test were used to characterize obtained
biocomposites. It was demonstrcted that when NC was added during the synthesis, it had no
effect on UPR viscosity. On the other hand, adding NC after the synthesis significantly increased
viscosity. Overall results showed that higher quantities of NC increased tensile strength, storage
modulus at lower frequencies, and decreased glass transition temperature.",
