In the present study, the surface of multiwalled carbon nanotubes (MWCNT)s is modified by ascorbic acid (AA) (vitaminC) for their dispersion improvement in the starch matrix. Then, the starch-based nanocomposites (NCs) containing 3, 6 and 9wt% of AS modified MWCNTs (AA-MWCNT)s were fabricated via ultrasonication method. Characterization of the prepared NCs was accomplished by different techniques. The optimum MWCNT content for the generation of fine electrical conductivity was found to be about 3wt%, indicating better dispersion of AA-MWCNT with low amount of AA-MWCNT. The adsorption efficiency of starch/AA-MWCNTs NCs is examined using methyl orange (MO) as adsorbate. Finally, it is concluded that starch/AA-MWCNTs NC is an effective adsorbent for the uptake of MO dye from aqueous solution.
在本研究中，通过抗坏血酸（AA）（维生素 C）对多壁碳纳米管（MWCNT）的表面进行改性，以提高其在淀粉基体中的分散性。然后，通过超声法制备了含有 3wt%、6wt%和 9wt%AS 改性 MWCNTs（AA-MWCNT）的淀粉基纳米复合材料（NCs）。通过不同的技术对制备的 NCs 进行了表征。发现产生良好电导率的最佳 MWCNT 含量约为 3wt%，表明低含量的 AA-MWCNT 具有更好的分散性。使用甲基橙（MO）作为吸附剂来测试淀粉/AA-MWCNTs NCs 的吸附效率。最后得出结论，淀粉/AA-MWCNTs NC 是一种从水溶液中有效吸附 MO 染料的吸附剂。
