Slovenian researches synthesized nanocellulose modified acrylic microspheres by suspension polymerization. In the first stage α cellulose was modified by acid hydrolysis and the produced nanocellulose suspension was added into the continuous phase of a suspension polymerization reaction mixture. The amount of nanocellulose varied in range from 0 wt% (reference synthesis) to 5 wt% calculated on monomer amount.hen, adhesives were coated via a transfer coating process and adhesive properties were evaluated.
A synergistic effect of lower particle sizes along with hydrogen bonding exhibited an increase in adhesive properties. DMA analysis showed that the storage modulus (G’) increased with increasing amount of added nanocellulose. At the same time a decrease in maximal tan δ values was observed which concurred with improved cohesivity, hence higher shear strength.
