Hydrophilic surface of -Al2O3 nanoparticles was treated with thiamine as a green modifier for better compatibility with poly(vinyl alcohol) matrix. In this regard, poly(vinyl alcohol)/-Al2O3-vitamin B-1 nanocomposites with different ratios of modified -Al2O3 (3, 5, and 7wt%) were prepared through ultrasonic irradiation and their properties were compared with the pure poly(vinyl alcohol). Many techniques were used to study the properties of poly(vinyl alcohol)/-Al2O3-vitamin B-1 nanocomposites. Morphology images of poly(vinyl alcohol)/-Al2O3-vitamin B-1 nanocomposites showed the good dispersion of the -Al2O3 nanoparticles in poly(vinyl alcohol) matrix in nanometer-scale. The results demonstrated that poly(vinyl alcohol)/-Al2O3-vitamin B-1 nanocomposites give better thermal stability, strain, and E-modulus than the pure poly(vinyl alcohol.
