Abstract

ABSTRACT Hydrophilic surface of α-Al2O3 nanoparticles was treated with thiamine as a green modifier for better compatibility with poly(vinyl alcohol) matrix. In this regard, poly(vinyl alcohol)/α-Al2O3-vitamin B1 nanocomposites with different ratios of modified α-Al2O3 (3, 5, and 7 wt%) 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)/α-Al2O3-vitamin B1 nanocomposites. Morphology images of poly(vinyl alcohol)/α-Al2O3-vitamin B1 nanocomposites showed the good dispersion of the α-Al2O3 nanoparticles in poly(vinyl alcohol) matrix in nanometer-scale. The results demonstrated that poly(vinyl alcohol)/α-Al2O3-vitamin B1 nanocomposites give better thermal stability, strain, and E-modulus than the pure poly(vinyl alcohol. GRAPHICAL ABSTRACT

绿色工艺合成聚乙烯醇/α- al2o3 -硫胺素纳米复合材料:热、力学、接触角和形貌研究

采用硫胺素作为绿色改性剂对α-Al2O3纳米颗粒的亲水性表面进行处理，以提高其与聚乙烯醇基体的相容性。为此，采用超声辐照法制备了不同改性α-Al2O3比例(3、5、7 wt%)的聚乙烯醇/α-Al2O3-维生素B1纳米复合材料，并与纯聚乙烯醇进行了性能比较。采用多种技术研究了聚乙烯醇/α- al2o3 -维生素B1纳米复合材料的性能。聚乙烯醇/α-Al2O3-维生素B1纳米复合材料的形貌图像表明，α-Al2O3纳米颗粒在聚乙烯醇基体中具有良好的纳米级分散性。结果表明，与纯聚乙烯醇相比，聚乙烯醇/α- al2o3 -维生素B1纳米复合材料具有更好的热稳定性、应变和e模量。图形抽象
