Cellulosafibrer är attraktiva förstärkningsadditiver för polymerkompositer, men deras hydrofila natur skapar svag fästning till de flesta polymermatriser — ett problem som direkt påverkar mekaniska egenskaper och processbarhet. Forskare vid Hamburgska universitetet har utvecklat en metod baserad på SET-LRP för att pfropfa akrylatmonomerer på cellulosafibrer, vilket ökar kompatibiliteten. Genom att testa flera akrylatkedjor med olika längd och polaritet — butylakrylat, stearylakrylat, dokosylakrylat och di(etylenglykol)etetyleterakrylat — kartlade teamet hur monomerstrukturen påverkar slutresultatet. Kompositer blandades med ABS och analyserades via SAXS, DSC, FESEM och kontaktvinkelmätningar innan de 3D-skrivs via FDM. Resultaten visar hur ytmodifiering kan justeras för specifika tillämpningar. För tillverkare av cellulosaförstärkta termoplaster öppnas möjligheter att optimera fibermatrisfästning utan att byta baspolymer, vilket förkortar utvecklingscykler och sänker kostnader.
