The objective of this investigation was to meliorate the physicochemical properties of corn starch-based polymeric nanocomposites (PNCs) by accommodating different levels of thiamine chloride assigned as vitamin B1 (VB)-treated carbon nanotubes (CNTs). The PNCs were acquired by solution casting method as a green method. The effect of CNTs@VB amounts on different properties of the PNCs including; hydrophilicity, structural properties, Cd(II) removal as well as optical traits was surveyed. Transmission electron microscope and field-emission scanning electron microscope images exposed that the CNTs@VB were fine distributed in the starch matrix. X-ray diffraction spectra of the PNCs displayed characteristic peak of the nanotube and also a decline in polymer crystallization after CNTs@VB incorporation. Compared with the intact starch, the PNCs indicated an improvement in thermal stability. The removal percentages of Cd(II) were amplified with raising adsorbent dosages to 0.08 g.
