Abstract

Poly(methyl methacrylate) (PMMA)-cellulose nanofibers nanocomposite were prepared by an immersion precipitation method using various nanofiber contents. Solvent exchange was used to disperse the cellulose nanofibers in dimethylacetamide (DMAc) so that they could be easily mixed with PMMA solution. Atomic force microscopy images show that the thickness of the nanofibers dispersed in DMAc is around 2–3 nm. The nanocomposites obtained were translucent. The thermogravimetric and differential scanning calorimetry analyses show that with increasing cellulose nanofiber content the thermal stability and the glass transition temperature (Tg) of polymer matrix shift to higher temperature. The tensile modulus and strength increased with increasing nanofiber content. Dynamic mechanical analysis profiles show that the presence of cellulose nanofibers affects the storage modulus of PMMA nanocomposites over the whole range of temperatures studied. © 2012 Wiley Periodicals, Inc.
