This paper reports green nanocomposites made by blending polyvinyl alcohol (PVA) with cellulose nanofiber (CNF) isolated from recycled deinked copy/printing paper (DIP). The reinforcement effect of DIPCNF in the nanocomposites is compared with other CNFs isolated from native cotton and hardwood by means of TEMPO-oxidation. The prepared PVA-CNF nanocomposites are characterized in terms of morphology, chemical interaction, structural, thermal and mechanical properties. X-ray diffraction and Fourier transform infrared spectroscopy confirm the reinforcing ability of cellulose nanofibers into PVA. By blending CNFs into PVA matrix, the thermal stability of the nanocomposites is improved and DIPCNF shows similar enhancement effect with COCNF and HWCNF. The prepared nanocomposites exhibit 50% Young’s modulus improvement by adding 6% of CNF and DIPCNF exhibits similar enhancement of the mechanical properties to COCNF and HWCNF in the nanocomposites. This indicates that the use of DIPCNF is beneficial for environment protection, resource retaining and save energy in comparison with COCNF and HWCNF.
