Abstract
Polymer nanofibers are valuable materials that are of great importance because they are inexpensive and they display high strength. In this study, nylon-6,6 (N6,6)/graphene oxide (GO) nanofibers were developed and characterized. GO was synthesized from graphene using the known Hummer’s method. GO is obtained by reaction of the graphene with strong oxidants and was characterized using Fourier-transform infrared spectroscopy (FT-IR) and scanning electron microscopy (SEM). The characterizations showed that the graphene was suitably oxidized. GO was added to N6,6 to produce N6,6/GO nanofibers at loadings of 0.5, 1.0, 1.5, and 2.0 wt% through the melt mixing method. The batch adsorption model for Cr (VI) adsorption was applied as a function of time, initial Cr (VI) concentration, adsorbent dosage, and pH to examine nanofiber activity. N6,6/GO a exhibited high adsorption capacity for Cr (VI) at pH 2.0. The maximum adsorption capacity for Cr (VI) ion was found to be 47.17 mg/g of N6.6/GO using the related isotherm curves and equations. When the equilibrium data were examined, it was concluded that Langmuir adsorption isotherm was more suitable.
Highlights
There is a grade demand to use corrosion-resistant and solvent-resistant low-density organic materials for simple installation and industrial purposes
It was interesting to ascertain that nylon 6,6 could be rearranged to amidoxime functions and they have good complexing properties toward metal ions in the aqueous phase (Pantchev et al 2007)
graphene oxide (GO) was produced from graphene nanoparticle via conventional Hummers method
Summary
There is a grade demand to use corrosion-resistant and solvent-resistant low-density organic materials for simple installation and industrial purposes. Polyolefin, polyester, polyamide, and vinyl are some examples of imperative groups of organic semi-crystalline polymers. It is well-known that semi-crystalline polymers are liable for the crystal phase charge transfer, that is, mechanical and non-viscous mechanical behaviors capable of applying incredible physical force depends on this phase response (Pouriayevali et al 2013). For this reason, it is important to enter into details about the crystal phase of semi-crystalline materials used in industry. Polyamides (nylon) as a group of semi-crystalline polymers joined with nanomaterials have received great
