Dispersion Effect of Cellulose Nanofibers on Mechanical Properties of Poly(2-Methoxyethyl Acrylate)-γ-Poly(Acryl Amide)

Abstract

We prepared the composite materials of poly(2-methoxyethyl acrylate)-γ-poly(acryl amide) (PMEA-γ-PAAm) with cellulose nanofibers (CNF). CNF can be dispersed successfully in PMEA-γ-PAAm matrix. Dispersion effect of CNF on mechanical properties were investigated using tensile test and rheometer. Young’s modulus of the CNF composite fairly increased in comparison with the original PMEA-γ-PAAm. In addition, the rubbery plateau region was clearly observed in the viscoelastic spectra of CNF composite. It is concluded that the CNF and acrylic polymer including acryl amide group form an interaction which plays a pseudo-crossliking role.
