摘要

Most hydrogels are prepared with using synthetic polymers that are nonecofriendly materials. Also, hydrogel nanocomposites are mostly prepared in the multi-step processing through costly techniques. Here, starch as a natural, biodegradable, hydrophilic, and inexpensive material was used for fabrication of a copper ferrite starch nanocomposites hydrogel. This was synthesized using alkali starch solution along with copper and iron salts through coprecipitation method at low-temperature led to the one-step gelatinization and retrogradation. The various characteristics of the nanocomposites hydrogel were examined including morphology and chemical structure besides magnetic, antimicrobial, and swelling behaviors. Further, the remaining ashes were considered as a simple method to estimate organic matter and inorganic nanoparticles content of hydrogel nanocomposite. The results indicated successful fabrication of a green hydrogel with magnetic and antibacterial features through a very simple method. The obtained ecofriendly hydrogel can be used in various applications such as controlled drug delivery, cancer hyperthermia, waste-water treatment, and many others. (c) 2020 Wiley Periodicals, Inc.
